UPDATE on CMMG .22lr conversion
UPDATE on CMMG .22lr conversion. I returned my unit to Brownells, explained that the spent cartridge would not eject and other problems. Brownells 100% satisfaction no-matter-when-you-bought-it is the BEST. Not only did they replace the unit with no questions, they even had one of their Tech guys actually TEST FIRED a new unit before they shipped it. This took a couple of extra days but I didn't mind. Brownells even sent me a check for my return shipping automatically! This is customer service at it's finest!
The new unit simply dropped it like you would expect it to and cycled just fine. The new unit was tight, unlike the first one, when removed and in your hands. The phosphate finish was not overdone like the first one and the overall final finishing was much nicer.
At the range, the mags fed well (same Big Dog mags I had to clean up though to work, these were not replaced) and the CMMG unit functioned almost perfectly through 100 rounds with only one failure to fire (bad round as the firing pin hit hard) and one failure to eject (again maybe the cheap Federals I used).
So, my conclusion, I must have gotten one made either on a Monday, made by a newbie or a monkey did it, because there was a noticeable difference between the two units.
Nonetheless, the replacement unit is a very nice and I'm glad I purchased it. So is my son! And Brownell's has made me a customer for life!

Great Customer Service CMMG!
My old CMMG kit has served me well for about 5k rounds. I had a little trouble removing it after my last range trip. I found that the chamber adaptor was cracked. I e-mailed CMMG's customer service to let them know. Garson shot me an e-mail back within minutes asking what kit I had (black or silver), and my address. UPS delivered a new chamber adaptor to my door 2 days later. 2 thumbs up for CMMG and their customer service. :happy:
CMMG Unit Damaged Upper Receiver
The Stainless CMMG .22 Conversion Unit that I recently purchased has damaged my upper receiver. After shooting, I literally had to forcefully
yank out the unit and discovered a 1.25 inch cut on the left side of the S&W M&P 15A receiver extending rearward from the chamber.
Would really appreciate recommendation from AR 15 savvy moderators. Don't plan to re-install unit anytime soon.
