Hey guys this is my first gun ďreviewĒ after lurking on here for a while armed with the great info from this forum. Iíve joined the AR22 crowd and am quite pleased with the outcome of sourcing parts together and building one myself. Itís my first AR and itís just great to practice so cheaply. After itís assembled I had Bain & Davis in San Gabriel (Great customer service!) test fire it and itís good to go so I took it to the range to zero it and planned to have some fun. I ran into some issues and I want to see what you guys think.

Setup:

CMMG Revolution Upper with 22LR Panels
CMMG 16Ē LW 22LR Barrel
CMMG Stainless bolt and collar
New Frontier Armory LW-15 Polymer Lower (No centerfire upper yet so no BB)
CMMG BHOA
Magpul MOE Rifle Stock with A2 buffer kit
Daniel Defense rear fixed sight and UTG front sight
CMMG 22LR Magazine Black skeletonized Gen 2?

Since the Revo upper is ambidextrous there are screw-on plastic/polymer panels on both sides for different setups. Half of the left panel blew off several feet behind me and missed my face when a round blew up inside. Note the Crack by the crew. I've put it back in place temporarily. The white blotch on the crack is after whacking it back into place.

Here is the panel that blew off

It was a nasty Remington Thunderbolt. I figured I shoot various brands to test it out. It was about the 20th round of Thunderbolt that malfunctioned.

I proceeded to skip the Federal Lightning and Blazer rounds and went straight to the Mini Mags after reattaching the panel and no failures after that.

I am not here to trash CMMGís design since I think itís just the el cheapo Remington. Although if the panel was aluminum I donít think it will blow off the upper since there was no internal damage other than a glitter sized flake of brass that was stuck on the inside of the upper that came off with a touch of the finger. Would this be a warrantee issue? If itís just the cheap ammo then Iíll just eat the cost of buying another panel but what when a bad round does explode wouldnít regular uppers handle it without any issues since itís all aluminum? Maybe CMMG might consider that option just in case.

I have yet to sight it in yet since I was having trouble adjusting the front sight correctly but figured it out after I got home. The rear sight adjusted fine.

Gripping aside, this thing shoots sweet! Despite not being sighted in, itís a tack driver for a beginner in ARís like me. There was one FTE of the Rem before the blow up and after that no FTE/FTF of the 50~ rds of CCIís. Not feeling recoil was very nice since Iím coming from shooting 30-06. Follow up shots are easy to shoot very fast. Magazine works well although it only holds 9 rds at the moment. Perhaps some break in is required. Cut spring maybe?

Overall I like this setup a lot, very lightweight, balanced and nimble weighing in at 5.29lbs. The finish of the parts all match very well despite being from various manufacturers and different materials. Iím really impressed with the fit and finish of it all. The polymer fire control group has a positive feel. Safety has a nice click and the trigger is light and breaks clean with no creep, very impressed.

It still needs a muzzle deviceÖ Iím not a fan of the pronged flash hiders so I prefer a brake for looks only. Iím having a hard time finding a brake that has the mounting diameter of .600 so itíll be flush with the barrel. I like the shape of the JP Bennie Cooley brake and the AAC Shorty. Other this, once I get it sighted in itíll be even sweeter.

Contact CMMG about the panel.
I had a discussion not long ago about this very potential issue.
An AT upper is designed to blow up or down in case of a OBD.
I was concerned about the side panels and what might happened in the event of an OBD.
So there is the result.
I'll stick with my mil spec uppers.

OBD's are generally caused by crud build up on the chamber/bolt face. Keeps the bolt from fully closing.
This can happen quickly with dirty ammo like the Remington.
Keep it clean.

Yeah, I'd call CMMG. I also agree that the panel blew because it was plastic and likely wouldn't have done that if it were aluminum and that CMMG should replace the panel under warranty. I blame CMMG for the panel breaking, and I blame remington for the crappy ammo.

But man... when are people going to stop shooting thunderbolts?

"Why does my gun get dirty faster shooting thunderbolts"
"Why does my barrel have lead build up shooting thunderbolts"
"Why does my gun blow up shooting thunderbolts"

Not trying to bag on you specifically, I just wish enough people would stop buying the things so remington would get a clue and straighten out their act.

give us a buzz Monday and we will replace your panel. With an OOB the panel may give, as in your case, with no damage to receiver.

As soon as we hear from you we will get one on its way to you.

Thank you guys. It was about the 20th round of Rem and it cause enough build up to do this? This stuff is horrid! I'll stick with CCI from now on. I figured I give it a shot lol. No offense taken, Merc. I should have known better.

CMMG, thanks for the the quick response. I noticed the right panel is bulging in the middle where there was no gaps before. Perhaps that can be replaced also?

For cheap shooting, I recommend the Winchester or Federal 36 gr. copper wash bulk pack sold at Walmart for about $20. 550 rounds

Just so you guys know, I also have a Revolution upper or my Tango build with several hundred rounds through it and no issues. So it's not the norm.

Everything seems to be moving slow right now. I'll see if I can get it expedited.

Stay away from Remington ammo. Just my .02. 36 grain Winchester Hollow points are what I use.

Remington .22LR ammo isn't good for ANY gun in my experience

I know I am resurrecting a very old thread but I also own a left-hand .22LR Revo upper. I've not shot it much but it has worked perfectly.
I've considered selling it so just took a look on the web and it appears that CMMG no longer builds Revo's. Does anyone know why they stopped production?
Thx,
B

Looks like CMMG standardized their product line down to 3 keymod FF rail configs with different barrels, an M4 and M16 looking model, and then one with m4 handguards and a railed gas block. Seems pretty similar to their 5.56 offerings. Products come and go, looks like what's left is probably what was selling.
