I have a basically new LWRC short stroke piston upper for sale sitting on a Spikes Tactical Crusader lower with ALG ATC trigger (~4.5 Lb pull). This is a complete LWRC upper, not a custom build. It’s got the LWRC quad rail before they went to that weird proprietary handguard. Looking at the photos you’ll see there’s no evidence this rifle has ever been fired. Even the firing pin still has the original grease.
***EOTech NOT INCLUDED, but can add for the right offer.
