CMMG Ar-15

What other ar15 brand are bargain bin cmmg rifles comparable to?

 

I think but please check for yourself that the non bargain bin CMMGs sell for $1000 to over $1200.

Their bargain bin rifles come from swapping or selling uppers and lowers separately over the year. Sometime every year(s) they go through the storage and put together their extra lowers and uppers thus making a complete rifle which they call their bargain bins.This is what I was told when I called them.

I have two. Their fit and finish is as good as anything I have encountered and their warranty is lifetime; unlike some of the other manufactures. So does that make them better than brand x with a year warranty *Bushmaster comes to mind* not necessarily.

CMMGs are mil-spec ARs and mine have fired any ammo I have placed in them. I am not a purest though. I just want something that works for me at a good price and other than the logo I don't care if they come from "Bugger" King.

are yours new cmmg's or bargain bin ones?

 

Both of mine were hand picked +$25 chrome lined +$50 Bargain Bin specials. None of mine came with any scratches or marks on them. They worked out of the box and I have had no problems with either. You do not have to get the Chrome lined barrels I only did because I will pass them on to the kids and can't guarantee their cleaning methods.

 

CMMGs are generally pretty good stuff. If the rifle indeed meets those specs then you are buying a very solid gun. If you plan to shoot a whole lot of rounds through it, make sure to take a look at the bolt carrier group and make sure the gas keys are properly stakes, proper components are used for the extractor, etc...you can find out what to look for if you search AR threads on here. If you feel nervous about the bolt you could always buy a full-auto BCG from Bravo Company to keep as backup. CMMG is solid though, you won't regret it.

 

Just a WAG since each one varies but for the baseline $600 BB - something on par with DPMS. I would spend a couple hundred more and select the parts I wanted. No doubt you can get a good deal with the bargain bin but I'm picky so will pay more. A brand new CMMG is an average AR and who knows what you'll get out of the bargain bin. You can get so much more with the extra money.

 

the upper is near-milspec. All it is missing is HPT on the barrel (high-pressure testing). It is MPI'd and uses proper barrel steel according to advertisements, although there is apparently controversy over whether or not that is true. No one has come forward with metallurgy test results to disprove CMMG's advertisements, though.

Their carriers are now all staked properly, but their bolts suck. Make sure you replace the bolt with a good one. The bolt is the only real issue with CMMG, that keeps them from being a top-tier AR manufacturer. If they would put better bolts with their gun, then only a select few brands would surpass them for quality versus price (namely, BCM and Daniel Defense).

With that said, I got my CMMG way back when. I got it with a full-auto carrier and asked them to upgrade to LMT's much, much better bolt. I have since replaced the BCG with a BCM one. My CMMG has not ever missed a beat, the barrel stays cool, the machining is ridiculous (especially the feed ramp cuts), finish is great, and it is superbly accurate (under 2 MOA or so with PMC and UMC).

Better buys out there for the money, but with a better selection of bolts, CMMGs will do anything.

The Bargain bins are made of mish-mashes of parts. The barrels are usually nitrided and probably aren't subjected to proper testing. Lower brands are mixed, finish is meh, and they have no warranty on them. However, no one has reported a problem with them. I'd put them on par with something like Del-Ton for being a great value buy.

 

I bought a CMMG bargain bin 18" barrel AR-15. It looked great !!! Unfortunately it would not shoot Radway Green SS109 and Silver Bear .223 ammo. The extractor ripped the rim off the case and left the spent round stuck in the chamber. I sent it back and CMMG did not fix the problem. I sold it......

 

I bought a 18" hand picked bargain bin early this year, it was a CMMG lower and looked flawless, At the range I noticed a rough chamber and then had a gas ring failure which locked the bolt solid. I shipped back and the they replaced a out of spec bolt carrier and polished the chamber and had it back to me inside of a week. I've since put about 500 rounds through it with zero issues. I've found it to be as accurate as I can shoot (about 4 moa with iron sights or aimpoint)

 

Here is a post on my recent CMMG BB, it's post number 57

I have put just over 500 rounds through it so far and it hasn't had a FTF or FTE yet. Upper and lower mate up tight and all the pins stay in place, even when bump firing. I have a Colt 6920 that I bought unfired from a guy and if I hadn't got such a good deal I would have let it go. The upper on the Colt has what looks to be wire wheel marks under the anodizing, not something I would expect from a 'high end" gun.

On the other hand, the CMMG looks great. I am going to order another next week so it arrives when I get home from some business travel.

HTH's

 

I've only put about 300 rounds through my CMMG. The upper is all CMMG, the lower is RRA. So far, I've only fired M193 and 55 gr reloads w/ the LC brass, but operation has been flawless. It's more accurate than I am, as I am only shooting with irons.

I bought it because of the quality of materials used, and the testing. Personally, I was happy with mag-particle testing. A pressure test would be nice too, but it wasn't as critical to me.

 

I've had 2 BB's for a couple of years now. It's fit and finish and function have been flawless. If your intention is simply for a range toy, the price is hard to beat.

 

do you know if CMMG's BB rifles have mil-spec steel barrels? If they do, then 650$ plus shipping is one BAD ASS deal. Almost makes me regret spending 750$ on my Spikes upper and DSA lower.

 

In a word, yes. This whole 'mil-spec' thing is mostly nonsense.

Example: MIL-B-11595E, the specification BCM claims to use on their barrels.

Let's see what the spec says: http://www.everyspec.com/MIL-SPECS/MIL+SPECS+(MIL-B)/download.php?spec=MIL-B-11595E.014406.PDF

Page 3: This spec is for barrels made of 4150 steel. So yes. Are these barrels made to a certified process standard to meet this spec? No, probably not. They'd likely pass all the tests required by the spec, but since they don't follow the spec word for word, they don't claim to build "to specification."

 

Think a barrel made out of 4150 is a tad bit better than 4140. Probably not gonna wear either one out at my advanced age but it makes me feel warm and fuzzy.

 

Better *if* you're running full auto. 4150 will tolerate heavy, sustained fire for longer than 4150. For normal to heavy semi-auto fire users, there's practically zero benefit 4150 provides over 4140. But if it makes you feel happier, more power to ya.

 

the main difference than the milspec standard and regular 4150 is the vanadium count. Milspec steel according to the TDP has a 'slightly' higher vanadium count in the steel.

CMMG has not published the exact percentile make-up of their barrels. Not many others have, either. But they still claim they meet the certification, and the people who say otherwise haven't given cause to believe otherwise.

 

CMMG sold me a rifle with an out of spec chamber. They wouldn't make it right either. I won't buy anything from them again.

Just remember.....Spikes guarantees their stuff........The CMMG bargain bin has no warranty at all.

 

I own a CMMG upper Double Star lower AR15 and I could not be happier. for $599 I got a rifle with 1 scratch where a tool had been on the flash suppressor. I hand picked it from Black Rifle in Columbia MO

 

Great article on ARs

Fixed the thread sorry.

 

How does CMMG stack up against the "chart"? I'd spend $200 more and get a decent Milspec rifle from Spike's with a lifetime warranty.

 

"bargain bin" and "AR15" shouldn't even be in the same sentence.

In any case, you get what you pay for.

 

thanks sky that's a good link

 

Taken from the bargain bin order page on CMMG's website:

As-is implies no warranty service. The fact that they (allegedly) shipped a rifle that had an out of spec chamber could be a different issue. If their site says it's been head spaced and test fired then they are responsible for that aspect of it, but if it was damaged in shipping they are not responsible and you would have to take that up with the carrier. The burden of proof would be yours.

FWIW, I have a CMMG factory (not bargain bin) rifle and it runs like a top.

BTW: I am not a lawyer, and nothing I say/type/write/etc is meant to be taken as legal advice. Thank you.
