Thanks, bro. I’ve been shooting black rifles for about 6 years. I don’t pretend to know everything, so I ask alot of questions. I appreciate the info. As my knowledge on the subject progressed, so has my choice in carbine. I started with BM, then went to S&W M&P, and now I have a BCM middy. I’m being anal and want to do everything right.
I forgot to add “Carrier/Gas key getting loose”.
I understand. Everyone wants a weapon to run as reliable as possible, for their intended uses. Don’t worry about asking questions. We are all here to help.
Gale McMillan builder of the most accurate barrels on earth. Designer and maker of the McMillan Tactical Tac-50 the rifle used to make the longest confirmed sniper shot in history. A kill shot from over one and a half miles away. Whose rifle barrels held seven world records at the same time and far more during the course of his life. He says, that barrel break in is a total waste of time and may cause damage to the barrel, from excessive improper cleaning. He says he has little experience with chrome lined barrels and they may benefit from have some rounds fired through them to smooth out any imperfections from the chrome plating process.
After cleaning & lubeing your weapon, barrel included of course BushMaster recommends running several hundred rounds and only cleaning when accuracy becomes affected.
Personally I clean my weapon with Gunzilla wipe it down and call it good. Gunzilla leaves excellent dry lube that has my AR run much cleaner and cooler. Than just break the gun in as a whole in make sure all the parts mate well and operate smoothly. After a 500 to 1,000 rounds without any failures it is a reliable go to weapon
I unscrew it…not a big deal. John Noveske told me that properly made barrels don’t require break-in.
