Working with CMMG from the beginning was a breeze. I purchased the 10mm Banshee and am completely satisfied with it. Great quality, works with all types of ammunition, handles well. I later added a Banish suppressor (.45 cal) and the gun works flawlessly. Great customer service and advice from the company.

I have had two of the CMMG 22 LR conversion kits and eight 25 round magazines for over 10 years. They have performed flawlessly in multiple guns. If you have an AR-15 and you don't have one of these you are missing out!

Building my own PCC using a CMMG AR-9mm upper and my own lower. If you've tried this for yourself, you know already that getting uppers and lowers to play nice with each other and run reliably isn't as easy as just pinning them together. CMMG support has gone above and beyond helping me figure out the best bolt and buffer weights. We're not done yet, but well on our way, once again, thanks to CMMG support. The AR-9mm upper is a superb piece of workmanship as well. CMMG is truly a 5-star company!
