Bushmaster Gas Piston ORC BCW3F 16M4 GP NS Complete Specs and Full Gun Specifications

The Bushmaster Gas Piston ORC bring new levels of reliability to the "AR" type rifle platform by eliminating carbon build up, gas leaks and heat within the Upper Receiver. The Gas Piston System operates by tapping gas pressure off the barrel much like the systems found on AK-47s and FALs. This Gas Piston O.R.C. (Optics Ready Carbine) is designed for shooters who intend to add optics such as holographic sites, scopes, or red dots. Functions with a wider range of ammunition - less gas pressure - lower cyclic rate. Offers improved reliability and control - with cleaner operation and reduced recoil. Keeps carbon build up and powder residue from reaching - and fouling the Upper Receiver and Bolt Carrier. A Detented Plug in the Gas Block allows easy cleaning of the Systems' Hard Chrome Plated Piston. Receiver Length Picatinny Optics Rail with Two 1/2" Optics Risers. Six-position adjustable telestock. Shipped in a Lockable Hard Case with Operator's Safety Manual, 30 Round Mag, Yellow Safety Block and Black Web Sling.
