Exactly what I was after. Grip received was the gen 2, not the gen 1 ergo that is pictured, but still extremely happy with my purchase.

Need to revise earlier review after completing some builds. LMT specs are not up to the hallowed tier they have a reputation for. Sloppy variable gapping with LMT uppers, and castle nut barely dimpled. The Axle trigger also leaves a bit to be desired when compared to a Larue MBTS.
