If you are in NE Georgia I recommend Concept Arms in Anderson SC. Their service is great. I found them based on a recommendation from Grady’s Great Outdoors.
The recommendation from the owner of Grady’s is always good.
On my first visit the owner at Concept was talking with a regular customer who had a high end pistol he had purchased from a homeowner who had experienced a house fire. The customer wanted some work done and the owner talked himself out of the job with good advice to the customer.
Just picked up a browning blr that they did a trigger job on for 350.00, haven't had any gunsmith work done in probably 25 yrs it has went up some lol. Had 2 older shotguns of my dad's that weren't cycling well I had tried everything I knew to do, they also went thru them one did have a broken bolt carrier wound up with 731.00 for the 3 guns. Work is warranted. They were nice guys.
