Just arrived today! First impressions, I'm in love! Same great cheek weld as the Magpul ACS but weighs considerably less at least to me. It is also slightly longer than the CTR I'm currently running which allows me to get a better cheek weld. I got it from Joeboboutfitters for $80 shipped. Now I just need to decide whether to keep the CTR on my SBR build or sell it and pick up another STR?
