I popped my bolt out today for a wipe down and new lube and I had to really pry the cotter pin out because it was bent. I've never had this before.

Upper is a BCM 16" ELW with Colt M16 BCG, about 2K rounds on all.

Lower is an LMT with standard VLTOR A5 and Geissele SSA.

All ammo has been M193 or MK262 clone loads.
