CMMG Reviews 

You will not find better service after the sale. Their products of which I have several are top shelf and rarely need service when properly maintained but should something fail as all things do at some time or another, they are quick to respond and solve the problem. Read their mission statement and their commitment to the 2A. Great company made up of great people.

I've always been a huge fan of cmmg as the very first AR15 i ever purchased was the cmmg mk9 way back 2017, I still have that gun and it still runs like new, I've since built many different ar15s and most of them have cmmg lower parts installed, that said I have bought and wear often cmmg shirts I think I have four or five now but ordering from cmmg is easy from parts kits to shirts to today when I ordered the new cmmg mute-ish 22 cal suppressor complete with a Keychain that threads onto it , when I got the txt link a few days ago ,I knew I was gunna have to get myself one of them , it will be my ninth can so far but it literally took five min from start to order confirmation , I would have to invent something bad to say about cmmg. Truth is they're are a solid company ran by solid people and make a superior products. Thank you

This is the trigger that should have came standard with the CMMG MK47 mutant as its obvious that most 7.62x39 ammo is steel based. Me having to buy it because of light primer strikes in a firearm with under 2000 rounds through it is trash.

It’s been over two weeks since I placed an order. Placed the order on 9/11 and it’s now 9/26. I just received an email that only part of my order has shipped, but the tracking number provided doesn’t say which carrier you are shipping with. I have check USPS, UPS, and FedEx, none of them recognize the tracking number provided.

I can’t get anyone on the phone and I’m waiting for an email response. I have no other choice but to give you all 1 star at this point. Word of advice, don’t ask for a rating so early into the process, especially when the customers haven’t even received the parts that were ordered.

I love your products I am a customer for life so far. I have recommended ya'll a couple times now. I know I will be buying more from ya'll for sure.

Complete and easy transaction. Great products.

Love CMMGs products. Wouldve been nice to have tracking. Ordered on 14th and still have not received any notification from my FFL it has arrived.

Super fast shipping. Item looks great.

Was easy to order. Delivery was sooner than expected.
However it did not fit my m5 lower n upper. The "wings"were too wide for the receiver. They were not angled as far out as the OE.
I fitted it using a dremel n it feels n runs great now. The metal is extremely hard n resists wear. It seems much stronger n better quality than original.
If you have a m5 lower n the thick upper, this will require significant fitting to be shaped like the one on an m16a2.

Very easy to use site.order delayed by 1 day but not a big deal to me. Product appears to be of good quality,will know better once it is installed.

Great product, fast service.

Quick delivery. I did find them cheaper afterwards but I was excited after ordering my first suppressor I didn't look anywhere else. The treads were perfect and the shims made it easy to time.

Fast, friendly customer service and a very easy website to navigate. Shipping was quick and received my items within 7 days of ordering.

Very prompt and always courteous replies. Answers all questions I have clearly. On customer service alone, I will always refer CMMG to others.

Time from order being placed to order being shipped was very long.

Great AR-15 22LR conversion kit! Love it!!

Shitty service. Not even a phone number to contact. Ordered a mk57 upper to replace the original mk57 upper that blew a case inside. So contacted them via email, because they dont have a damn phone number to reach out, they told me I could return it and they would check it out. But when I sent them tons of pictures of the inside of the upper they are trying to say it is the ammo. So I decided screw it I'll just order another so I dont have to deal with the BS with them. You would think being they are the manufacturer they would keep in stock, but apparently it takes 15-30 days to complete a damn order. I should have just ordered one off of buds gun shop for like 200 bucks less and it would have been here already.

The parts were ordered and delivered very quickly.
