I have a CMMG 4.5" build with a .22 Spectre 2 suppressor.
Out of curiosity, what kind of accuracy are you guys getting with similar builds? I am going to zero mine soon for 20 yards with a Vortex Crossfire 2 1-4 scope. Just want to get an idea of what to expect. 
Thanks |

I bet you'll be surprised how accurate it is. I have a CMMG 6.5" barrel on a pistol and at 50 yards with a red dot and not even trying I put mag after mag into an area smaller than the palm of my hand with Federal bulk pack ammo

My 4.5" cmmg barrel and suppressor are all over the place (6" group) at 10 yards. Still fun to shoot though.

Something is definitely wrong. 10 yards is almost close enough to reach out and touch with your hand. If you meant 100 yards then that isn't quite as bad but still could be better with some different ammo |

Are either of you guys that are running the cmmg barrels having feeding issues? Have you tried ejecting a live round after it fed to check and see if it is getting torn up? I have a cmmg 4.5 inch barrel / collar combo that I can't get to feed reliably enough to attempt a Zero of the sights. I've eliminated every variable but the barrel / collar. Cmmg is shipping me a new collar (great customer service so far). Out of a 25 round mag, about 4 or more will fail to feed. If I eject a live round the bullet tips are bent sideways, and some of the lead is scraped onto the casing. I wonder if this is happening with you guys to a lesser extent, just not enough to cause a FTF.

I have a 4.5" barrel from member Redtazdog(sp) and can break clays at 75yds, with a reflex dot sight, with boring accuracy. Something is up with the ones that won't group.

My taccom 4" shoots very well. I've never sat down and shot groups but I can break clays and 50. It will easily keep a mag dump on a 10" plate and that is just screwing around.

I had a 6.5" and the accuracy was very impressive. I cut it down to 4.5" and it's not nearly as accurate now, although still a ton of fun and it now keeps everything subsonic.

I polished my feed ramp to a mirror finish with a felt wheel on a dremel and some polishing compound. Didn't change any angles, just shined it up. Made a big difference. Quote HistoryQuoted:

These inaccuracy stories are not cool.
I told my wife that the 4.5" CMMG barrel is what I wanted for Christmas this year. I hope I didn't make a big mistake on supressor host choice :( |

I tried my 4.5" cmmg without the suppressor today and the groups tightened up. It appears that the suppressor is to blame. No baffle strikes either.

I have and come to think of it, my buckmark's accuracy was off too. I hadn't thought about it being the suppressor since I changed barrels at the same time. I need to get a rest and do a more controlled test.

Any updates OP?
I received a replacement collar from cmmg last week and made it out today. Gun runs 100 percent now. Going to try and make it back out tomorrow to shoot from a rest and see if I have any strange accuracy issues like others in the thread. |

I'll be testing mine in the morning with cci mini mag, standard velocity and federal bulk. Curious what accuracy I get now. Brand new 4.5" cmmg barrel and ss bolt kit.

I'd be ok with that, considering I threw my PA dot on my setup yesterday and was seeing 2+ inch groups from a rest @ 25 yards. Same dot on an off the shelf 15-22 of mine, from the same rest resulted in one large hole.

I ran into this same issue and was able to resolve it. Ironcically my 4.5" barrel grouped fine with my can, but when I put that same can on my 16" barrel it was all over the place. Turns out the threads were too long on my M&P15 -22. Standard length AR15 threads are too long for a 22 can and cause the bullet to be unstable. Gemtech makes an adaptor which reduces their length. I bought one and problem solved.
I wasn't having baffle strikes either. It took me a little while to figure out what was causing it. Hopefully that's all that's wrong with yours. Quote HistoryQuoted:

I put mine on paper recently. 4.5" CMMG with sparrow. 25 yards with a PA red dot and you can cover 10 shots with a quarter easily. This is with cci sv and blazer. Oh yeah I also have the fun switch on my registered receiver. Most fun set up you can shoot!
