Review of my personal midlength Intro: Last summer I got the itch to pickup a dedicated carbine course/home defense rifle. I had owned a few ARs before, but wanted something I could really beat the crap out of without reservation. I decided to go with the build route while utilizing quality parts. The build originated as follows: - LMT Complete lower w/SOPMOD - TD Battlegrip - Carbine buffer - VLTOR MUR - DD 12 M4 rail - Sabre Defense 16 1/7 midlength barrel - Addax Phalanx flash suppressor - LMT Enhanced M16 BCG - Badger ordnance ambi charging handle - Aimpoint CompM4s - Troy BUIS - TD VFG - VLTOR scout mount w/G2 led - Tac-link QD mount for single-point sling During my last year with this course I have fired a total of 6000 rounds through it. I have used it through EAG, Tricon, LMS, and Mike Pannone (CTT Solutions) courses. Here are a couple reflections on the components I have used: LMT Enhanced Bolt Carrier Group: Deep in my heart I know that all I need for a BCG is a quality milspec BCG that has been properly tested, staked, etc. Im not going to try to convince anyone otherwise. That being said, I have been thoroughly pleased with this product. LMT claims easier extraction due to longer dwell time, and a superior finish on the bolt itself. You can see their description here. My experience has been similar to their claims. Subjectively, I feel like the combination of this BCG with a midlength rifle reduces the recoil impulse very well, especially when compared to a standard carbine. I have had one failure to extract @ 5985 rounds. This was during a 500 round, one-hour shoot. The rifle was nearly burning my hand through my gloves. Ill chalk this one up to Murphys law (extractor looks fine), but I will annotate if this becomes a reoccurring issue. Finally, I must note that you should not consider this BCG if you plan on running it on a rifle shorter than a 14.5 carbine.
