RRA lower with a national match 2stage trigger The lower on my bushmaster cracked when the bolt carrier bottomed out no the receiver. I figured I'd get another lower so I can shoot it while on leave and send the lower in to get repaired, once it comes back I'll get an upper and have two ar's. XD40 with a 4" barrel. I was fighting between the glock and the XD. After shooting about 100 rounds through both today at the range, I felt the XD was a bit more comfortable to shoot. I also found it pointing where I want it each time I picked it up to aim. Seemed like I was aiming the glock down naturally. $950 all together. I gotta do the 3 day waiting period, I'll post the pictures of everything once I pick it up.
