Sureshot Armament Group has teased a couple of images of a prototype PCC that they are planning to launch soon. I reached out to Valentin Vlasenko, the founder, co-owner and chief engineer of SAG, who kindly told me some details related to the mechanism of operation and other design features of this upcoming pistol caliber carbine.
This PCC utilizes a gas-delayed blowback mechanism of operation. There is a gas port drilled in the barrel that vents gasses to a separate gas chamber pressurizing it and pushing against the piston. The piston is attached to the bolt carrier group, however, instead of pushing the BCG back the piston pulls it forward thus delaying the opening of the action. Once the pressure in the bore and the gas chamber drops to a safe level, the force pushing the bolt back and inertia overcome the forward pressure of the piston and throw the BCG back thus cycling the action. One of the advantages of the gas blowback action over the direct blowback is the possibility to use lighter weight reciprocating parts. Probably, the most well-known firearm utilizing a gas-delayed blowback mechanism is the Heckler & Kock P7 pistol.
This Sureshot Armament Group PCC has a polymer lower receiver. The company plans to have two iterations of the lower receiver designed to take Glock or Vityaz magazines. The bolt head is removable which will allow changing the caliber by installing a proper bolt head and barrel. The trigger mechanism and the pistol grip are borrowed from the AR-15. The lower receiver is connected to the upper via two pins.
The upper receiver of this PCC features a top Picatinny rail. The handguard design shown in the pictures will be changed and the upper receiver on the production version will be compatible with Remington ACR handguards. This PCC will also have an ambidextrous reciprocating charging handle.
According to Valentin, one of the reasons of developing this PCC was to make a good quality pistol caliber carbine at an affordable price. They are targeting to have an MSRP of €850 which by current conversion rates is roughly equal to $960.
We’ll keep following this project and report about its development and launch. Stay tuned!
