Pretty sure Spec is shooting at 25 yards.
Not bad Spec. I'm taking the CMMG M4LE to the range tomorrow. I'll post results. Dave |
|
Oops, it was 25 Yards. Those would be great targets at 50.

Rifle looks GREAT. The scope fits right in. Wish I had a nice quiet, small range like that.
Even when I go to Dade City, 55 miles away it's first come first serve,, packed. Groups are consistent with what I'm getting, sept you opt for 10 round instead of 5. So, I suspect you're shooting better than I am. Last picture, Nice Splat. Dave |
|
That was a butterfly. It was shooting so well I couldn't resist.
I'm going to drop a 2 stage trigger in it. We will see if the groups will tighten up more. I had one of those stupid moments at the range. Guy shows up in a camo boonie cap and a C.I.A. polo shirt on[>:// A couple younger guys come over with a 10/22 they have questions about. Mr. C.I.A. pulls out his wallet. Here we go. He starts telling these guys about all his "C.I.A. ops. So I was already annoyed. Finally the guys leave. He starts talking to me. Starts trying to tell me his Ops stories. I've heard all this crap before. I handled it well though. I gently told him about all the guys I've met in my adventures who claimed to be SEALS, SF, Recon ect...and I felt it was a dis service to the guys that actually did the job, like my old partner and best friend. Suddenly, someone gave him the shirt and he actually worked as a jailer, but of course also worked for the State Department. So I was ready to leave, reached down to pick my rifle up and found the scope was loose! Stupid! I didn't check it. So a lot of groups I shot were with the scope loose in the rings. But the ones I posted were a good representation of how the ammo shot. Just wish I would have done it earlier than after 600 rounds.By then I was ready to go. Dave |
|
Just to add, I ran my 16" 5.56 upper on the CMMG lower today. Everything checked out just fine.
|
|
I think we're having all the fun shadowcop. Hopefully some of these uppers will be going to the range with
other ARFCOM Members soon. Then we'll have a flurry of range reports to add. Spec |
|
John said the uppers are going out as fast as they build them. With the value and quality that they are, it doesn't suprise me.
I'm looking forward to seeing some groups from other members too. The two stage combat trigger is sweet. 4.5lb. clean break. It feels like a shorter two stage than the RRA. Being a Combat trigger, it has a needed heavier pull than a match trigger. I believe they will offer two versions. The Combat 2 stage with 4.5lb. pull (available now) and a 2 stage Match trigger with 3lb. pull. The brass bushings are a nice touch. I've got to find some more Winchester 555. It's all gone here. Fortunately the rifle shoots Fed Bulk just fine. Even with the inconsistant loads. I'm not sure whart CMMG does to these that makes them run so well, but I'm glad they figured it out. Nothing more frustrating than going to the range and having to work on the rifle to get it running. Cut this spring, polish this, trim that, change this, ect... My CMMG conversion and dedicated CMMG M4 LE .22 has run absotutely great. I like plug and play. |
|
CMMG sent a fully upgraded stainless bolt. It has all the final options including the
cotter pin. I'll be shooting it tomorrow if the world doesn't end before then. I'll try to take some 555. We'll see how that works out. Spec |
|
No doubt, the 555 will run great. I'm looking forward to the results.
|
|
Guys, the Winchester ammo your talking about, does it only go under the name of 555? I see it as only 525. Is there a difference? Thanks
|
|
The 555 and 333 is sold at WalMart. It's a copper wash hollow point. 36 gr. I don't know if it's the same as the 525.
It's Winchesters version of the Fed 550 bulk pack, also sold at WalMart. Except it's very consistant. |
|
It is a 36 grain copper plated hp. I am getting it from Cabelas. When all the rage was Fed big box, I loaded up on those. My son and I could hear different sounds, i.e., pop vrs the poof. But they still worked well enough to have a great time. Thanks
Just ordered my second major component from Bravo Co. They are selling blem flattops for 69.00. Thought that was a good deal. |
|
It's probably the same round. If it's consistant and copper washed, it would be good to go for me.
|
|
I'll let you know what mine does with the CMMG 2 stage trigger I just installed.
I found some Winchester 555 and 333 over in Kentucky. I'll check around tomorrow and see if I can find some match ammo. |
|
Went to the range.
The CMMG 2 stage is nice. It has a heavier pull than n RRA 2 stage but the CMMG is more of a Combat 2 stage. 4.5lb. pull. I shot Winchester 333 and Eley EPS Match. I shot some groups about 1-1.5" at 50 yards. It was very windy. I was also having some scope issues so I'm not posting any pics yet. Aggrevating day at the range. Good news is, I shot another 483 rounds with not one failure. I'm at about 1650 rounds now with no failures other than the Remington Subs. Accuracy has been very good for a blaster barrel. This rifle really likes the Winchester 333 and 555 bulk. Good news for me! |
|
The trigger I'm using is a standard DPMS Single Stage that I did the set screw mod to.
I've used so many heavy triggers that my carry weapons are set to 8 lbs so I don't shoot myself in the leg getting one out. Don't know how I'd do with a real trigger job. Your 1-1.5" at 50 yards sounds pretty good, wind especially. I've had more failures than you but I always warm up with Federal Bulk.... |
|
What kind of failures have you had? I didn't even think about it until the drive home. Not one failure. It makes shooting so much more enjoyable.
You also have one of the very early set ups too. So far this .22 has been as reliable as any of my AR's. I'll be back there in a couple days. Another problem I've been fighting is trying to shoot the rifle off the bench with a high cap mag. It just makes keeping the same cheek weld hard for me. I ordered a 15 round mag today. That will be one less struggle. Dave |
|
I reached 2000 rounds today without a single malfunction.
Shot some Eley XSP with very good results. 5 rounds touching. Winchester 333 still shooting dime sized groups at 25 Fed Bulk is just aggrevating. Nice 5 shot group then 2" off. Bang, bang, pop, bang, pop Never get anything consistant with it. I still couldn't get on the 50 yard range. Maybe Monday. |
|
Basically, I have 2000 plus or minus a few rounds through the upper.
99.9% of the failures have been ammo related and possibly the couple ( The 0.1% ) that got caught in the upper were too (Weak Loads). I've been experimenting with a lot of variables and prototype stuff. Different mag springs, followers, forward assists. I'm not really doing any troubleshooting because CMMG is mirroring what I'm doing here. I've been getting new parts every few days. CMMG just wants to confirm that I get the same results they do. They're trying to ensure that the customers will be 100% Satisfied / Thrilled with what they receive. I believe the verification process of all the peripheral Evolution Parts is nearing completion. Everything I received seemed to work fine. So much so that I think they played a joke on me with a miss matched bolt and rail so I'd complain about something. Maybe they thought I could do something magical and it would work for me. I haven't had a lot to complain about. Hardest thing so far was getting the BHO Mag Spring worked to a point it would accept the full round count... Personally I think I would load 15 to 20 rounds and call it good. Even with the spring set, loading 21-25 is hard on the hands. The spring has to be tough to work the standard AR-15 Bolt Latch. Dave |

Dave While the mags can certainly be loaded to 25 rounds, for maximum service life of the mag, we will recommend 20. BTW, have a SST mag loader at the stamping shop now. We have tried a couple polymer ones but they didn't fare so well when going past 22 rds. We can't wait to get this stuff going. It is progressing nicely. The tough part has been getting this drop in unit to work with the wide variety of firearms out there. |

Spec, I would expect some failures with what you are experimenting with. I'm not running the mods you are. But that is what I like about CMMG. They won't release the stuff until they know it's right.
I think I'm going to have to clean the rifle. I want to be sure the accuracy problems are ammo related and not due to the crown being carbon up or crud in the bcg. At the same time, when the shots were making quarter sized groups with Fed Bulk and then going to 2" at 25 yards, I ran the Eley and had the best group I ever shot with it. Group was under 1/2" at 25 yards. I'm also wondering if the different scope was throwing me off some. It's a 3-10 power scope. Parallax is probably set to 100 yards. So it would be easy for shots to be off at 25. I'll keep working at it. I have a 8-25 scope with an adjustable objective I may use. I just hate pulling it off my target .223. This has truly been the most reliable .22 rifle I've ever shot. Dave |
|
I've got a new style conversion unit to try out. This is going to be very interesting.
I have accuracy data on the rifle I want to use. This is the smoothest conversion bolt assembly I've seen. It's stainless steel but there's some brass and space age plastic parts too. The latter is in non critical to function areas, of Course. Spec |
|
That's very close to what we're seeing, Winchester 555 hasn't been the most accurate
ammo in my Sierra Upper. You shoot well for being one of us FOG's Try some different ammo and you may stumble across what yours prefers. You will be amazed at the groups you'll shoot then. They'll be smaller than that dime. Fed Bulk, Winchester 333, 555 are great for killing Coke Cans but aren't the most accurate...CCI Standard Velocity might work well in these.?????? Dave |
|
Mine likes the Winchester. Mini mags work well too. I di need to get some CCI Standards if I can find them.
The groups with Eley Match were great. Too expensive for my taste. |
|
I guess I got a peach of a CMMG .22lr convo kit - I've ran two bricks of 'terrible' Federal 39gr, and only had one failure (ammo related still).
Glad to see that these are running well. |
|
I've got about 4000 rounds of Fed Bulk left. It runs real well, just not accurate and very inconsistant. If the rifle feeds the crappy Fed bulk, I know it will feed good ammo.
You would think Federal would have figured out by now that their Bulk packs set on the shelf while Winchester is always out. |

Dave I picked up some mini mags I am going to try and if I can find some standard velocity CCI I am going to try some too. I have just been shooting the 555's because Wallyworld had a lot of them and they run great. BTW Last time I was at the range I had a guy come up to me and asked what the hell kind of rifle I was shooting because he had a Colt .22lr AR and he couldn't shoot more then 6 or 8 rounds through it without it jamming and I was shooting mag after mag through mine without any problems at all |
|
I know I keep repeating myself but the CMMG has been the most reliable semi auto .22 I've ever shot.
If you want to see what it will do, get some Eley Match. If I had better glas, I velieve I could come close to putting them in one hole. I was using a Mueller Sport Dot that has a 1 mil dot. All tounds were touching. |
|
Even though my Sierra doesn't prefer Winchester's 333's / 555's, it's still lethal enough to kill
100% of the Coke Cans at 25 yards...The Sierra Upper is just as shadowcop mentioned. Reliable and the accuracy is really pretty good with the better target ammo. Very comparable to other companies entry level uppers. It's more than adequate for all but matches where accuracy is everything. That being said, CMMG will eventually offer a high end barrel for the Evolution System, just another way to cover all the bases. Dave |
