The accuracy and lightweight performance of Proof Research meets the innovation and rugged dependability of JP Enterprise's PSC-12 upper receiver. This complete PSC-12 comes with the JPBC-4 low mass bolt carrier group, 17.25" MK III free floating modular hand guards, adjustable gas block, side and top charging handle, and 3-Port compensator. Assembled by JP and ready for your AR-10 DPMS style lower. This upper is chambered in 6.5 Creedmoor and has a 22" barrel with a 1:8 twist rate. CAMGAS: With the release of its new patent-pending Caliber Matched Gas System (CAMGAS) barrels, PROOF Research has eliminated the issues traditionally associated with building 6.5mm and .260 rifles on 308AR/AR-10 platforms. Until now, AR-variant shooters looking for ballistic advantages from either of these calibers were faced with excessive bore pressures that necessitated makeshift solutions such as clipping buffer springs, adjusting buffer weights, and/or relying on adjustable gas blocks, to keep their rifles functioning properly. PROOF’s R&D team has solved the overpressure issue with gas systems tuned specifically to the cartridge/barrel-length combination. “By moving the gas port, the pressure in the bore is given time to reduce to that comparable of a .308 Winchester with a rifle-length gas system, which is what the 308AR/AR-10 system was designed around,” said Greg Hamilton, PROOF’s research-and-development weapons specialist who’s also a 3-Gun and PRS competitive shooter. “The recoil impulse is noticeably smoother, which helps keep you on target while taking advantage of a more efficient projectile. Case extraction is also easier, with less case-head smearing, so the brass is in much better condition for reloading.”
