Received this in my inbox today. Very exciting. The dual-charging PSC-12™ upper assembly features all the utility and advantages of its predecessor, the PSC-11™, available now for large-frame AR platforms. On the heels of the JP side-charge system's success on our other rifles, the PSC Series not only offers a unique new take on this feature by incorporating both side-charge and traditional top-charge systems into a single upper receiver, but also by making this innovation cross-compatible with existing DPMS LR-308 lower assemblies. The PSC-series combines the great features and performance of virtually our entire rifle line into a single package designed for the all-out tactical market with its redundant charging systems, dust cover and forward assist. In addition, the PSC-12™ is also available as a complete rifle built on a modified version of our LRP-07™ billet lower with the full selection of stock, grip and trigger options available.Base Rifle Specifications:[table][tr][td] Receiver: [/td][td]Machined-from-billet 7075-T6 upper receiver with left-side charging system and modified LRP-07™ forged lower[/td][/tr][tr][td] Receiver Finish: [/td][td]Matte Black Teflon finish over hard coat anodizing on aluminum components[/td][/tr][tr][td] Barrel: [/td][td]JP Supermatch™ 416R air-gauged, button-rifled, cryogenically treated barrel[/td][/tr][tr][td] Barrel Finish: [/td][td]Polished stainless[/td][/tr][tr][td] Muzzle Treatment: [/td][td]JP Compensator[/td][/tr][tr][td] Caliber: [/td][td].308[/td][/tr][tr][td] Buttstock: [/td][td]A2 or ACE-ARFX[/td][/tr][tr][td] Grip [/td][td]Hogue pistol grip[/td][/tr][tr][td] Hand Guard: [/td][td]JP Modular Hand Guard System[/td][/tr][tr][td] Gas System: [/td][td]JP adjustable[/td][/tr][tr][td] Operating System: [/td][td]JP .308 Low Mass Operating System (LMOS™)[/td][/tr][tr][td] Trigger [/td][td]JP Fire Control Package available in weights of 3.5 - 4.5 lbs.[/td][/tr][tr][td] Accessories: [/td][td]JP accessory pack including operator’s manual, one magazine, GasGunBasics™ DVD and more[/td][/tr][/table]
