Took the inherited AR to the range with iron sights and the new Timney trigger. Wanted to make sure it wouldn't go full auto like it did before I got it. The test firing never happened. Inserted the loaded magazine that came with it, released the bolt and hit the trigger. No bang.
Long story short my brother-in-law had 222 ammo in the magazine instead of 223. The 222 goes in the chamber so deep that the firing pin won't reach it.
Before passing I think he had mental issues.
Oh, and I scrapped that old BSA reflex sight.
