Anyone else have their lowers perform spontaneous mitosis during sales?
I have two uppers (8.5" 300Blk suppressed and 11.5" in 5.56) that share one lower. Somehow it magically spawned another and now I have two complete guns.
Total mystery, and a complete coincidence that the same lower was on sale the other day.
I use 20rd mags for 300Blk and 30rd mags for 5.56 to avoid cross-contamination. How do you separate yours?
