These are great *true* ambi lowers. Most so called “ambi” lowers sold by others are not fully ambi — nearly alol are lacking the bolt lock back function, which is probably the most important and useful part! Great for clearing weapon, making safe, etc. no need to swap grip on weapon. Just grip and rip with left hand while trigger hand/right hand remains where it is depressing bolt catch. Fantastic.

Nice ambi lower with near-symmeric controls designed to be used similarly from both sides.

BTO helped facilitate easy transfer with my local FFL.
Left side mag release is more stiff than right side, hopefully that will break in a bit more over time. Minor cosmetic issues. This is my first LMT product, I will buy more.
