I have a rifle I put together from two different rifles. Rifle started at as a Special Edition 20" heavy fluted LT. Tactical 1:10". I had the barrel threaded 5/8-24 and a custom thread protector made. The Hogue overmold stock came off an AAC 300 Blackout that I purchased. The trigger is the X-Mark Pro that it came with (I have not adjusted it in any way). So basically this is the same as the Rem AAC in 308, except it has a much cooler 3 flute barrel. I installed a rail and scope and zeroed it, then I removed the rail and scope and never touched it again. 10 rounds down the pipe, it is very much like new. $850 + shipping to your FFL. USPS money order only.
