^Second this. LWRC combines the best of both by using a piston to drive the accurate and familiar M4 (AR-15/M-16) platform. Add the high quality parts they use standard and you have accuracy and dependability w/o hours of maintenance. Mine's an M6A2, and it is my go-to. Now, as for perfection of application, make it a 6.8 and you truly have a carbine that is fully superior to both platforms in almost every way. But the military hasn't taken the step to go there... (too much 5.56 NATO around to wholesale change it I suppose). Will my ACR completely replace my M6A2 as my go-to? Only time will tell on that one...Try LWRC! Noveske is an awesome weapon too, but I would pick an M6A3 from LWRC.
