I had a not so great range day the other day.
1. Apparently you are supposed to clean the BCG and firing pin of a SBR that runs suppressed full time.
A squirt of oil on the charging handle and BCG are not gonna get it.
2. I was shooting .300 Blk and only that. I stupidly did not have all my mags marked and had a fellow shooter lay a pmag off 5.56 on top of my .300 blk mags... When I discovered it, I freaked out, I thought I had somehow loaded 556 in my mags and thought that the fresh box of .300 blks came mixed with 556. After a few mins of WTFing, I figured out, it wasn't my mag, it had a grey button on the bottom and all mine I think are black. I ordered 2 12 packs of those rubber mag bands and a Silver Sharpie... That mix up, could have caused me or the other shooter a rifle, hand and or face...
3. Apparently, my knees are shot.
I can get down and shoot prone with no issues, but shooting while kneeling, not going to happen unless I have no choice, then its debatable...
