Great product and a good price. - AIM Sports Inc AR-10 .308 M-Lok Handguard

The only 13.5inch m-lok rail for my 308 build I could find. Solid build, only issue is the internal anti-rotation mechanism. This anti-rotation piece of aluminum sits on top of the gas tube. Once place on the gas tube, it would not fit in the rail. I had to grind it down to fit. Still a good purchase. Just expect to do some grinding. I think that is going to be true for any DPMS 308 build. Do your research before hand. Not as easy as an AR-15 build.
