I’ve owned 8 cmmg firearms over 10+ years, and all have been excellent. Most importantly, they’ve been incredibly reliable. Everyone of my home defense firearms that stays ready to go is a cmmg, specifically a dissent in .300 and a banshee in 9mm. I can’t actually recall a single malfunction from any of them.

I invested in a 5.7 CMMG upper to go with a SBR lower I owned. It’s super great quality and beautiful and also I’d definitely do it again any day and recommend as a 5star quality business and super great customer service. They even replaced my 5.7 AR magazines that had a recall update no charge.
By Shane B.
Products are top notch and customer service was great. Bought a few items from the site itself and other vendors and they are all good. The only time that I had a bad product (brought a barrel but was not threaded but was advertised as threaded) customer service was quick to respond and act.

What I needed at a good price.

CMMG makes great innovative products. The website is informative. I would consider adding a blog comment on using FRT devices on the Banshee model in particular, tips and traps, since this is an obvious pairing for many users. I think videos addressing various known issues are great, too.

I emailed customer service about a feeding problem and they suggested a tuning kit. I ordered one and got it quickly and it solved the problem.

Loved getting the email about the new Zeroed Banshee and pre ordering it couldn't have been easier. I currently own a Banshee and have been very impressed with it.

Great company, great products. I love the idea of a tucked suppressor. You guys listened to your customers.
