(2 out of 5) LMT mars
by Brian from Chicago, IL on July 6, 2018

Upon shooting the rifle for the first time, the rear site came completely apart and the staking on the bolt carrier gas key is complete garbage.

(5 out of 5) Outstanding Rifle
by Cameron from St. Louis, MO on August 24, 2018

Don't listen to the other guy that reviewed this rifle, he doesn't know anything. I blasted off 8 mags without a hitch after getting this bad boy in the mail yesterday and I have to say that it is probably the best AR you can get right now. I'd even take this LMT over a DD or a Knights, and I'd certainly take it over any service rifle I had to use in the past. I'm looking forward to competing with this rifle in some upcoming trooper matches.

Pros: Extremely accurate and zeroed out of the box Very rugged. Comes with a torque wrench, rail panels, QDs, sling, and magazine SOPMOD stock is the greatest that ever was or will be. MARS lower has actually useful ambi features

Cons: Absolutely the worst box Ive ever seen, really surprised that they didn't include a case. Magazine has the puke green tilt machine. No idea why they can't put a good follower in.

Buy this rifle. MSRP is like $2850 and you are getting it shipped for $1500 so it is a steal.
