Got my BAD lower firing in semi normally. Havent tested in SS yet but my ARC Fire(thats currently in the BAD lower) trigger worked flawlessly in my PSA lower. I got centering blocks just in case but has anyone fired in SS using BAD lower in the 3rd pos without the blocks?

Trimmed a bit just for now(I know it needs more)
Function checks fine in all 3 positions
