Ain't Broke, Don't Fix It?
14.7" CMMG M4 Profile Barrel
I bought my CMMG back when people had a much higher opinion of them. I’ve been in the Army for about 4 years now, so I haven’t put near as many rounds down its throat as I’d like. But after I get back from “over there” in January I’m pretty much out of the Army & I’m looking into shooting a lot more often “for pleasure”.
Back when I bought it I broke it in with 180 rounds of XM193, then 500 rounds of Wolf Polymer for a total of 680 rounds. I never had a single malfunction of any type.
Since I’ve been deployed, I’ve become an avid lurker here on the site. And I was lucky enough to find "the Chart", so I already upgraded to a BCM BCG & H Buffer. The upgraded stuff is waiting for me when I get home.
Long story short is this. CMMG is notorious for having 5.56 marked barrels but tight .223 ish chambers. Not only could this cause problems with my Wolf stockpile, I just plain don’t like having to worry about that kind of stuff!
Easy solution right? Send her on down to ADCO and get the chamber reamed for $30. But I haven’t had any problems with it eating my Wolf yet.
• Am I being overly paranoid?
• Should I wait till I have a problem, even though I believe in prevention?
• I know people say no, but “can reaming have any negative effects at all”?
• Should I just say screw it and buy a BCM or Daniel Defense barrel and call it a day?
Hey, thanks a lot. This place has been awesome!

We few, we happy few, we band of brothers;
For he to-day that sheds his blood with me
Shall be my brother; be he ne'er so vile,
This day shall gentle his condition;
And gentlemen in England now-a-bed
Shall think themselves accurs'd they were not here,
And hold their manhoods cheap whiles any speaks
That fought with us upon Saint Crispin's day.
