This is a collection of posts on another forum about the CMMG BB AR15 I ordered a couple of weeks ago:
Just picked up the CMMG Bargain Bin 1/7 twist chromed bore
hand picked AR that I ordered a little over a week ago. They come coated with plenty of oil.
First impressions are that it is a NICE carbine! I might actually feel bad about getting the first few scratches on this one. I am going to hop on the band wagon of people saying these hardly look like something that has been knocking around in a crate or barrel somewhere. The only mark I could find was on the flash hidder.
Mine has a CMMG lower, M4 cut feed ramps and well staked gas keys.
I'm heading down to the man cave and run a feww patches down the bore, slap the EOTech on and put a few mags through it. More pic's to follow.
****If there is any areas you want to see close up let me know and I'll do my best.
UPDATE 1:
As I said in the Ordered a CMMG Bargain Bin Thread, it came in today so I thought I would post my first impressions.
After running a few patches through the barrel (it was dirtier than I expected...the only part dirty BTW) I headed out back to put some rounds through the new acquisition. While down in the basement I took an EOTech 512 (long battery compartment) off a middy and put it on the CMMG carbine. I loaded everything in the back of the truck and head out to the range. I ran down to set up the backer-board and target then head back to the bench.
The mags I used were a mix of 2 USGI, one old and one new, 2 Pmags, one older style and one newer without windows. I am new to the P-Mag game and it is my understanding there a few generations. All the P-Mags I have are the non-windowed versions, a few do not have the ability to have the cover snap on the bottom but most of them will take the cover on the bottom.
The ammo I used was a mix of different manufacturers and styles. Federal XM193, PMC 55gr FMJ, American Eagle 55gr FMJ, PMC 62gr steel core, Federal XM855 and Igman SS109. Yes I know it says American Eagle XM855 on the box. This was packaged in a Federal marked case, American Eagle box and loaded in Lake City brass. As far as the Igman goes, I bought this stuff years ago so if anyone can shed some light on it that would be great. It is black tipped with a red primer sealer.
First off, once I sit down I realize trying to shoot for accuracy isn’t going to happen this evening. The sun was setting directly behind the backstop. If anyone has a work-around for this when using an EOTech I would love to hear it.
I figured this would be a function test only at this point. I get set up, chamber a round and press the trigger…BANG…WAP. I got hit in the arm by the EOTech.
When I had it on the middy it would allow the battery compartment to hang over the handguard. When I mounted it on the carbine I guess I didn’t realize the handguard was a titch higher so the mount didn’t completely lock down. I moved it back, tightened it up and tried again…this time no problems.
Once tight, I was able dial it in well enough to hit paper plates at 100yrds and with the sun directly in my eyes I felt pretty good about it. I loaded 10 rounds in each mag and fired some rapid and some slow without a single hiccup. The only thing I didn’t care for was the trigger reset, it seemed a bit “clicky”. I have 2 stage Rock Rivers in my other AR’s some maybe that is the difference. All the trigger group pins stayed in place which is more than I can say for the Bushmaster. All the mags dropped free and the bolt catch worked everytime.
I put 200 rounds through it tonight and
hope to run more tomorrow with the sun at my back so I can get a better idea what kind of accuracy it’s capable of. I would buy another in a heartbeat, the market might go down a bit more, but it might not.
I have 719.00 into this one at this point since I opted for the handpicked version. This breaks down to 650.00 for the chromed bore, 1/7 twist, carbine, 25.00 for the handpicked option, 24.00 shipping and 20.00 FFL transfer fee. I also bought a rear Troy BUIS for 75.00 which should be here tomorrow.
I will post accuarcy results when I get a chance to get back out.
UPDATE 2:
I had a little bit of time this morning so I headed out to the range with the Bargain Bin AR. I found a local guy who had a Trijicon TA11D on an ARMS mount that I picked up pretty reasonable and thought I’d give it a try. I had also put smaller hand guard from my Bushmaster on so I could get the EOTech and the backup sights on the flattop at the same time.
I don’t have a true “rest” and I haven’t made up sandbags yet so I was using my Lead Sled…not the best set up when using an AR.
It took a bit of getting used to when using the illuminated triangle on the ACOG, I think I like the TA01 with the crosshairs better. It could also be the Shoot-n-See targets, the orange center seems to bleed into the illuminated triangle. I have also come to the conclusion that the trigger leaves much to be desired, I plan on doing something about that. It took about 10rds to get it somewhat on target and even then it seemed to settle in a bit low to my point of aim.
Here are the results of shooting 5 different types, weights and makes of ammo (I forgot to grab the Bosnian stuff). Since I sighted it in using the X-Tac 62 gr Green Tip, thats what I shot first. I shot 10rds of each type, at each target, from 100yrds.
Next was PMC Bronze 55gr (I am starting to REALLY like this stuff, it shoots well in the Bushy too) it's the only 55gr stuff that grouped well.
Then the Federal XM855 62gr Green tip (the best grouping for me today)
****I have two more pic's in the post below since I exceeded the 15 pic limit******
Lessons learned...
I need to come up with a better rest for sighting in AR's or anything with a pistol grip for that matter.
I think I am more of a crosshair guy when it comes to scopes, that triangle in the TA11D is pretty dang bright, there must be a way to dim it a bit.
The trigger on the Bargain Bin is a bit rough but it might smooth out with use.
The CMMG as not had a single FTF or FTE with 330rds through it.
I didn't have any Key-holing at 100yrds with the 55gr stuff and didn't have time today to move everything back to 200 yrds but hopefully soon.
Here the cost break down:
650.00 Chrome 1/7 twist
25.00 hand picked option
24.00 shipping
20.00 FFL transfer fee (I caught him on a good day, normally 25)
719.00 total
I would/will be buying another soon! I might go with a "luck of the draw" just to compare to the handpicked version.
