Bar and other gun repairs.
 

Anyone know where to repair bars? (Noob question) Also if you can please post as many places you know where people get get repairs.

Gun Point Shop. At the top end of it, and you have to grab the counter and I believe the npc is of 'Peter' idk.

usually it's where you purchase a gun. but sometimes it's at weird places, such as the gas shell shop for the morano Thompson. Fort Knox has a bunch of weapons you can upgrade that you can't normally buy, such as a pink m4 or an artillery cannon.
