"Excellent fit and finish on this upper. I placed it on a dpms lower with no problems. Added all my extra goodies with no hang ups. Just waiting to get some range time!"

"I bought a Bushmaster A2S carbine used and attempted to install a rifle length handguard and low profile gas block on it.. I ended up going to a gunsmith who, in short order told me that he'd broken my upper.. What to do? Enter CMMG.. This upper is absolutely fantastic.. Perfect fit and spectacular quality.. Love the weight AND the looks too.. I would recommend this upper to ANYONE.. It is EXACTLY what I'd hoped for and is definitely worth the price.."
