Thread: The WORST Firearm You Ever Owned

Not a worst firearm ever owned but a near miss.
I bought an AR 22lr upper (CMMG Evo) off Trademe with 3x 15rnd mags.
I was so excited until I used it and found it couldnt go 5 rounds (sometimes less) without a fail to feed, fail to extract or jam a live round vertically into the underside of the charging handle.
After a few nights of cursing and scouring the internet - I found that the solution was to polish the feed ramp and the bolt rails and give the chamber a gentle buff.
It now runs flawlessly (much to my relief).
If the internet is to be believed even CMMG admitted that this was common and the finish was horrible as they cut QC to get more units out the door.
Happy now but without a tidy up it was an absolute dog.
