spare parts?
 

hey, somewhat new to AR's with a question:

what spare parts do you recommend keeping around for the AR? i own a S&W M&P sport.

firing pin? what else?

thanks for any input.

get mil spec lower parts kit.. maybe a bolt and firing pin.

I'd say a LPK and maybe a complete BCG. Only problem, they tend to morph into a new AR!

So why not cut to the chase and buy a spare BCM. :D

You know what they say about spares ... one is none and two is one.
