if your looking to get work done on a AR or AR type rifle in the reading area, Andy at Reading Armament would get my vote. I had him convert my Troy PAR in 300 blackout to 6.5 Grendel, now that i finally got a barrel and bolt. He did the work quickly considering I am planning on using this rifle for deer season. He was so much faster then other shops i have dealt with in the past with getting the work done as well. Since this not a typical AR rifle he needed to close the gas port on the barrel and get the pump mechanism to work correctly. now i just have to get my butt to the range.
