Recently, an article at Guns.com caught my attention about the side-charging upper receiver that will be released by QuarterCircle 10. Side-Charging handles are said to be novelties designed more for guns that will be used in close quarter battles, but what I do really fancy are the QuarterCircle AR pistols that are able to use Glock calibers, from 9mm to .45 ACP.

QuarterCircle 10 specializes in AR pistol lower receivers, barrels, and bolts that will utilize pistol calibers. We are actually more familiar with conversion kits designed to turn pistols into carbines such as the CAA Ronin, Magpul FPG, and the Hera Arms CPE as these already have airsoft versions and we're looking forward for the QuarterCircle 10 AR Pistols to be available as well. The advantage of AR pistols and carbine conversion kits over regular pistol is that they offer a more stable platform for shooting with pistol magazines and the perhaps shoot over longer ranges.

According to the company, real steel shooters will need a special bolt to fire the Glock magazines as these have smaller feed lips than the Colt-style magazines and there needs material to be taken out to properly feed the rounds.

As for the upcoming side-charging upper receiver,  it allows the shooter to remain in firing position while charging the AR pistol with the non-reciprocating charging handle. It also has a trap door in the rear to keep dirt out of the upper receiver. This is the first time that QuarterCircle 10 will be releasing an upper receiver

Well, the good thing for airsoft is that we only use 6mm (okay, okay, 8mm too) BBs, so we're not worried about the different calibers for the Glock magazines, though there will be some who might want the .45 ACP-style Glock gas magazine. And there are also 50-round Glock Gas Magazines in the market  and in airsoft this means that they can outgun a shooter with an M4 gas blowback given that most of the M4 magazines are at 30-32 rounds with the exception of the King Arms M4 Gas Magazine which has a capacity of 50 rounds.

If an AEG/AEP version also comes out, I wouldn’t mind too as there will be options for Glock-type AEP Magazines. I just hope an airsoft manufacturer reads this story and might be interested in having a tie-up with QuarterCircle 10 for an airsoft AR version of their products.
