Robinson Armament XCR-L in 5.56/.223. in like-new condition. The XCR basically combines the best features of the AK-47 and the AR-15. The XCR is a piston driven semi-automatic rifle that was designed to compete in the military's SCAR (Special Operations Forces Combat Assault Rifle) competition, and thus is very similar to the FN SCAR rifle. It has an olive drab green monolithic and m-lok compatible upper, a beefy AK style bolt and extractor, a length and height adjustable and folding stock that retains firearm functionality even while folded, ambidextrous controls, a nonreciprocating side charging handle with forward assist, easily adjustable 7 setting gas block, and the XCR quick change barrel/caliber system. The XCR is compatible with standard AR magazines and grips. This rifle has a factory installed 14.7 inch barrel with a factory pinned and welded muzzle brake, and thus an overall barrel length of just over the legal 16 inch requirement (was a $90 upgrade). This sale will include the original factory rifle case/tactical bag, one 30 round magazine, and the XCR instruction/maintenance manual. It will also come with a Robinson Arms AR Stock Adapter that allows for the folding stock to be easily replaced with almost any other AR style buffer tube/stock
