Starting my first AR build. I'm looking to build an A2 replica. Picked up my stripped lower from my lgs and would like to find other shops that carry parts or a shop that specializes in AR parts. I live on the far west side of Indianapolis so tell me all of your go to shops for parts.
I believe U.S. Defense Solutions has a good selection. Last time I was in there they were helping a few others with their builds. They have a section on the forum also.
We carry a wide range of parts and accessories for your build, from individual pins and detents through complete upper halves. We also have a couple of certified AR-15 armorers on staff to answer your technical questions. Stop by or give us a call and let us know how we can help!
