This is a middy length short stroke gas piston carbine, with an XCR style 4 position gas regulator, integrated flip up front sights, and Cold hammer forged Nitride barrel.
Hopefully I can have an M6A3 and XCR-M for B-day gifts in June. The American Arms makers are really stepping up. The new site is slick as well: http://www.lwrci.com/
Thats a nice M6A3 you got there. Im waiting for an upper to come in a few days and now I want to plan a new build with an LWRCI. Sheesh I have a problem.
