Review of the QC10 GLF.45 ACP AR Pistol by Quarter Circle 10
The popularity of pistol-caliber ARs has increased significantly over the past several years, and it seems that practically every manufacturer of an AR is entering the market. Most of those have, up until recently, been 9mm-chambered.
Although it may seem like a recent fad, some people have been engaging in this activity for a while. In reality, since 2011, Quarter Circle 10 has produced uppers and lowers specifically designed for pistol-caliber ARs in a range of calibres. Fortunately, Quarter Circle 10 manufactures entire pistols and carbines, and I recently got my hands on the company’s QC10 GLF in.45 ACP if you don’t want to build your own pistol-caliber AR.
Texas native
Cattle and guns are synonymous with Texas, which is where the moniker Quarter Circle 10 comes from. No, it might not be easy to say, but the name of this Texas-based business originates from a cattle ranch that was founded in 1854. That’s a lot of rich history, and it leaves the current business with a lot to live up to.
According to its own description, Quarter Circle 10 produces pistol-caliber carbine products. “Made for, not changed” is the company’s motto, which refers to the fact that it has always made parts specifically for pistol-caliber ARs rather than adapting rifle-platform AR receivers to accept pistol-caliber magazines.
Although the corporation has its headquarters in Texas, Tucson, Arizona, produces the lower receivers, and other parts are also produced in the United States. A black Type III hardcoat anodizing has been applied to the machined billets of 7075-T6 aluminium used to make the uppers and lowers. The lowers are fitted with buffer assemblies made for pistol-caliber weapons and put together using mil-spec lower part kits. The business adds an SB Tactical SOB brace and a straightforward A2-style pistol grip to the bottom for the QC10 GLF.
A large-frame Glock lower (like the one used in the test) can fit the.45 ACP and 10mm, and Quarter Circle 10 also offers lowers designed to fit 9mm Colt and HK MP5 magazines. Smaller-framed Glock magazines can be used with 9mm,.40 S&W, and.357 SIG firearms. There are also models being developed that can use Sig Sauer P229/P226 and Smith & Wesson M&P magazines. The serial number and production information are stamped on the right side of the lowers, and selector markings are stamped on both sides. The lowers have simple lines and few stampings.
A Closer Examine
The upper receiver of the blowback pistol has thicker walls than those of a typical rifle-caliber AR to boost rigidity and robustness. A wider ejection port is also seen for large-caliber handgun casings like the.45 ACP. Although a 7.5-inch barrel is also available, my QC10 GLF pistol came with a 5.5-inch barrel that was topped with an A2-style flash suppressor. A 5-inch KeyMod handguard that is free-floating and with QD sling attachment points on both sides surrounds it. Additionally, it makes use of a BCM Gunfighter extended charging handle and a dedicated.45 ACP bolt carrier group. One 13-round Glock magazine and a protective box holding the pistol’s top and lower parts are included in the package.
The QC10 GLF pistol costs $1,646, little more than a few other pistol-caliber ARs, but you get a weapon designed specifically for the.
45 ACP without any changed rifle components, mag well adapters, or similar accessories. While maintaining complete AR capabilities, such as the bolt locking back after the final round is fired, which you don’t always see on less expensive guns, the gun is as trim and compact as it can be. The only additional features I might want to see are a hand stop and a single-point sling adaptor, especially with the short 5.5-inch barrel. Both are simple aftermarket additions.
Range Setup
On a chilly, partly cloudy, 65 degree summer day, Jim and I went to the range. Along with my Huntertown Arms Guardian 45 suppressor, LabRadar chronograph, and a variety of weights and types of.45 ACP ammo, I had everything I needed for the range in my range bag. I chose the Holosun 510C reflex sight for the QC10 GLF, which is a wonderful accessory for an AR pistol or carbine chambered in pistol calibre. Its ring-and-dot reticle is quick to acquire and accurate enough for fine adjustments. It is battery-backed and solar-powered, and it is made to be left on so that it is always ready when you need it. I had a mix of 13-round Glock magazines and 13- and 26-round SMG Tactical magazines to feed the beast, so to speak.
The QC10 GLF is incredibly enjoyable to shoot. The platform scarcely moved when fired due to the overall size of the handgun and the AR buffer. You may greatly manage this package by adding the BATFE’s explanation from the previous year that it is once again acceptable to shoot your braced handgun from the shoulder as long as you don’t alter the brace from its original configuration.
Following-up Report
Overall, the pistol was highly reliable, especially when using standard-weight.45 ammunition. In actuality, the 165- to 230-grain loads did not experience any halts. The PolyCase Inceptor ARX load did initially result in a few failures to eject, but those appeared to disappear with future runs. These 118-grain bullets exited the 5.5-inch barrel at little over 1,400 fps, cycling the blowback mechanism of the pistol much more quickly than it was presumably intended to. With both PolyCase loads, the recoil and report were not unpleasant, but they were more noticeable than with the heavier. ACP 45 loads.
The precision of the QC10 GLF was very good. The majority of loads were printing at approximately 1 inch at 25 yards, with even the most basic Federal American Eagle 230-grain FMJs printing at less than an inch, showing that Quarter Circle 10 is doing everything properly with this setup. Even though the high-velocity polymer RNPs weren’t as popular with the QC10 GLF, they were still averaging less than 3 inches. Oddly enough, the greatest groups of all the loads from many shooting sessions came from the much lighter ARX load, which produced some amazing sub-1-inch, one-ragged-hole groups. The Holosun 510C also turned out to be a fantastic fit for the pistol, allowing for quick, accurate fire when moving or putting rounds on target while still being able to deliver pinpoint hits from a bench or a steady standing position.
“Covert Ops”
Just bare with me for a moment. One of the more intriguing weapons of World War II was the British De Lisle carbine. It was a.45 ACP chambered modified Enfield bolt-action rifle that took 1911 magazines and had a relatively large inbuilt silencer. It was a really powerful piece that was applied in covert operations. I’ve always had suppressed thoughts. Although my test weapon is not a carbine, the AR-based QC10 GLF is a contemporary interpretation of the 45 ACP carbine that used handgun magazines. I combined it with my 45-caliber Huntertown Arms Guardian suppressor to create my own modern-day De Lisle.
The new TRS Comp pistol from Nighthawk Custom is a full-sized, government frame 9mm double stack built around a match grade barrel and a monolithic slide. It’s built to compete and starts at $4,599.
The TRS Comp comes standard with a recon rail under the barrel and a dimpled rear cocking design that offers ample traction when racking the slide. It also sports unique dimpled frame and slide textures that match the grip pattern.
Integrated Compensator
The TRS Comp is Nighthawk Custom’s first full-size pistol designed around a double stack frame. It features a 17+1 capacity and incorporates Nighthawk’s Fire Hawk compensator, which boasts a precision-designed port that reduces muzzle flip for quicker follow up shots.
This model also features a unique dimpling texture found throughout the slide and grip, which provides ample grip while being snag-free during holstering. The TRS Comp uses a 14K gold bead front sight that does an excellent job catching light, coupled with a Heinie Ledge Black rear sight for quick target acquisition.
The pistol also features Nighthawk Customs’ Interchangeable Optic System (IOS), which is a dedicated dovetail machined onto the slide and allows for optic mounting with adapters. This system allows for an interchangeable series of sight options to quickly switch rear sights in a matter of seconds.
Interchangeable Optic System
Nighthawk Custom’s Interchangeable Optic System allows a user to switch from a plate with a traditional rear sight to a red-dot optic in seconds. This feature is especially beneficial for concealed-carry practitioners who want to train with a red-dot but still carry a traditional rear sight.
Nighthawk’s unique IOS system involves milling the top rear section of their slide to interface with an interchangeable series of sight options, including a Trijicon RMR and other red-dot sights. This low-profile system also incorporates a suppressor-height rear sight as a backup to the optic’s front sight.
The TRS Comp features a match grade 5.00′′ barrel on a government sized frame with a monolithic slide, a full-length dust cover and an integrated single-port compensator. This combination reduces muzzle flip and delivers faster follow-up shots on the range, a must-have for competitive shooters.
The TRS Comp is finished in black nitride for a sleek, durable look. The lightweight aluminum trigger possesses a serrated flat face and a gold bead front sight does an excellent job catching light, providing quick target acquisition. A Heinie Ledge Black rear sight completes the package.
Match Grade Barrel
One of the most important features of any match pistol is a properly fitted barrel. A true match grade barrel will have zero play in the muzzle or at the hood, and it should glide into battery smoothly without any drag or snag on the slide.
This is achieved by carefully fitting the barrel to all of the chamber hood contact surfaces and the lower locking lug. Once this is done it will have a true target fit and shoot groups that rival a 1911 handgun.
The TRS Comp is the first Nighthawk Custom model to be designed around a double stack frame, offering 17+1 capacity and using their integrated compensator, the fire hawk. The compensator has a precision port that reduces muzzle flip and helps shooters stay on target for follow up shots.
Unique Dimpled Texture
The TRS Comp is the newest addition to Nighthawk’s line up. It is a high-end double stack 1911 that packs a 17+1 punch, as well as a lot of style and class. It also happens to be the most accurate and durable gun in its caliber. It also comes in a variety of colors and finishes, from matte black to high-shine chromium. Its crown jewel is the aforementioned patented integrated compensator, which may be the best thing to happen to your sidearm in years. It is a real head turner, especially for those who don’t usually opt for the sexy gun. The aforementioned gizmo is accompanied by a precision designed port in the rear of the slide that reduces muzzle flip without sacrificing a hefty amount of power. The aforementioned gizmo features a matching name badge aft of the slide, as well as a match-grade 5″ barrel and a full-length dust cover with accompanying nifty-fun accessory rail.
The PC Charger is a pistol chambered in 9mm, and it can take Glock magazines. It is very popular and has become more of a sought-after gun than the original carbine.
Many owners of the PC Charger equip it with a brace to give it stability. This makes it a lot more shootable.
Ruger PC Charger
Ruger’s PC Charger is a pistol-caliber carbine (PCC) that combines the fun and utility of an AR style pistol with the reliability and accuracy of a high capacity AR. Designed to take both Ruger Security 9 and Glock magazines, the PC Charger is a highly customizable weapon that makes a great range gun or home defense tool.
Adding a brace to the PC Charger increases its stability and makes it more shootable. The brace can be attached to the MIL STD 1913 rail on the back of the pistol.
The SB Tactical FS1913 Brace is one of the best PC Charger braces available today. It is made of a polymer material that offers quick deployment and a lightweight profile.
This brace is perfect for a shooter who is new to pistol braces, and is looking for a compact and inexpensive option. It is also a good choice for people who are already familiar with the design and use of a buffer tube.
AGP Arms
The AGP Arms brace kit for the Ruger PC Charger is the best way to upgrade the standard stock and barrel. The brace is the logical extension of AGP’s acclaimed pistol grip Gen 2 stock and handguard, allowing users to customize their pc charger to their own specifications. The brace is the brainchild of a dedicated team of military and law enforcement personnel, many of whom have been in the trenches for longer than most of us will ever know. Featuring a modern twist on a classic design, the brace is an understated delight. Its most prominent feature is a cleverly engineered gearbox that enables the user to rotate the entire gun by hand, and then lock it into place using a single pin. The aforementioned pin is mounted in the rear of the gun, where it is tucked under a protective cover for safekeeping. In keeping with the aforementioned design, the brace is also anodized black for a look you can be proud of.
SB Tactical
SB Tactical is the inventor of pistol stabilizing braces. They were started in 2012 by Army veteran Alex Bosco after he designed a brace for his disabled friend so he could continue to shoot.
SB Tactical was the first to introduce adjustable pistol stabilizing braces. This was a big win for the industry and gun owners alike.
After getting pre approval from the ATF, they began selling pistol braces for AR/AK style firearms, CZ Scorpions, H&K MP5 designs, 1913 rails, and more.
The SBA3 is one of the best pistol braces on the market and offers 5-position adjustable adjustment, ambidextrous QD sling attachment points, and a Velcro strap to connect to your arm for one-handed shooting.
The SBA4 is another great choice and offers a sturdy M4-style strut, 5-position adjustable, and an integral QD sling socket. This is an excellent option for a Ruger PC Charger gun with a Glock drum, but it also works well on any pistol without a buffer tube.
Midwest Industries
Midwest Industries is a family owned and operated company that manufactures quality parts, uppers, lowers, rails, barrels, furniture and muzzle devices for AR platforms and many other firearms. They also have a number of innovative products and services that make them a great choice for those looking to upgrade their firearms.
Probably the most useful item that they manufacture is their Combat Rail Handguard in hard coat anodized 6061 aluminum. It features eight functional M-LOK slots and two anti-rotation sling swivels. Its hefty price tag might be a turn off, but its high performance and robust construction is well worth the outlay.
What you might not have known is that they also make the pc charger brace aka the FS1913. Basically the same as the name aforementioned but a lot more durable and the brace actually folds to a compact size for easy transport. They even include a nice looking sling with an integrated bottle opener to boot.
Mini Mamba is a famous YouTube Star who has earned a fortune as a professional. He has a net worth of $1-5 Million at the age of 11 years old.
Mambas are venomous snakes of the family Elapidae, which also includes coral snakes and cobras. They live throughout sub-Saharan Africa.
Black mamba
Black mambas are venomous snakes that are found in Africa. They can grow to up to 14 feet in length and are one of the longest venomous snakes in the world.
They are very fast and aggressive, and their venom is particularly deadly for humans. It takes only about 20 minutes for a bite from a black mamba to kill a person.
They live in grassland, savanna and rocky slopes of southern and eastern Africa. They are primarily diurnal and prey on small rodents. They have excellent vision and a highly developed sense of smell.
Green mamba
Green mambas are found in coastal areas of eastern Africa including Kenya, Mozambique, Tanzania and South Africa. These snakes are venomous, which makes them extremely dangerous to humans.
They are a diurnal species, which means they are active during the day. They also spend a great deal of time in the trees and rainforests of western Africa, where they live amongst the forest canopy and thickets.
This snake preys on birds, lizards and small mammals. Its venom isn’t as powerful as the venom of the black mamba or the red mamba, but it can still kill.
Green mambas breed during the rainy season. Females lay eggs, which hatch in about 10-12 weeks. Males seek out and compete for females by following a scent trail or by wrestling or dancing. These combats aren’t biting, but rather a way for the two snakes to establish dominance over each other.
Red mamba
The red mamba is a species of snake that lives in Africa. It is related to the black mamba and can be found in various countries throughout the continent.
It is a medium-sized snake that can grow to be 2 m long. They are mainly found in tree hollows and termite mounds.
They are very venomous and kill their prey quickly. Their venom is highly toxic and can affect the breathing, heart and muscle function of the victim.
They can also paralyze their prey, which they then swallow. They feed primarily on birds and small mammals.
Yellow mamba
The mamba is an African snake. There are four species: black mamba, green mamba, red mamba and yellow mamba.
The Eastern green mamba (Dendroaspis angusticeps), formerly known as the white-mouthed mamba, is a venomous snake that lives in coastal regions of East Africa. It is found from Kenya south through Tanzania, Malawi, and eastern Zambia.
The eastern green mamba is a shy snake that avoids humans when possible and only strikes if provoked or cornered. Its habitat is fragmented in parts of its range and it is listed as Vulnerable by South Africa due to habitat destruction and deforestation.
Blue mamba
Mambas are notorious for their speed and aggression, and they come in a wide variety of species. They are a common sight in Africa’s rainforests, and all have deadly venom.
Of the four types of mambas, the most venomous and dangerous is the black mamba. Known for its lightning-fast speed, erratic behavior, and painful bite, it can strike multiple times in a matter of seconds.
Its venom is highly neurotoxic and cardiotoxic, with fasciculins present to paralyze the muscles of a bite victim. The venom can kill a victim within hours of a bite.
