Name: Knr Gunsmithing. Descripton:KNRCertified gun smith. We find the root of the cause, not just replace parts. Ever had your gun "fixed" by a part swapper just to find out that it isn't or breaks down after a few hundred rounds? when you call them back they tell you it is going to be more money? We back our work up. If we cant fix it, you dont pay. give us a call.
