Years ago I bought a CMMG AR-15 from Outpost Armory. When I got to the range I had to drift the rear sight all the way to the left stop to get the danged thing to hit paper at 100 yards.

Like any other 22LR/AR on the market, run good ammo. I took my latest 9mm AR to the range yesterday and kept having doublefeed and stovepipe issues: My initial thought is to polish the feed ramp and check the extractor - any other items I should check? The build is: CMMG MK9 lower PSA 10.5 upper & ramped bolt KAK tube, PSA 9mm buffer weight, mi. The CMMG RDB system kills ejector springs in 9mm / 40SW and 10mm. That said, CMMG finally released the FE (Fixed Ejector) versions in February of 2025 but only for 9mm and 45. The ultimate tactical accessory, the new Tactical Bacon from CMMG ® is simply amazing. Kept in an aluminum can for a shelf life of 10+ years, the CMMG ® Tactical Bacon is more affordable than other pre-cooked bacon producers, who offer no tactical packaging for their product. It looks like the CMMG or PSA but with a trigger guard like a nice billet receiver would have.
