Must Have Spare Parts for AR15
Title pretty much sums it up...
Ar15s have parts and parts by nature can break or be worn out....so my question is what are the must have parts that a guy should have so that my AR15 will run for a very long time...
what parts tend to break or wear the fastest from your guys experience
should i have a few extra bcg's?
forgive me if there is a thread that breaks this down that i may have missed
