So I got ahold of a Samson Evolution keymod 15" because the price was too cheap to pass up. Wasn't sold on the design originally, thinking that it was a flimsy way of attaching the tube to the barrel nut via the thermal bushings. It just seemed that this is too many extra pieces for movement to occur. The directions weren't the greatest, no torque specs. Just said tighten until the tabs close together. Had to dremel/file/fit the anti rotation tabs to fit onto the billet receiver. Not too hard, just tedious. Finally got it installed and went to sight in on bipod. The handguard slipped forward during recoil after only 4 shots. I had used blue/ med locktite and it had time to dry. Next used red locktite and let sit overnight, tightened the tabs a little more to the point just shy of breaking them off. Overall, not really all that satisfied with the product. I believe that there are way better designs out there, but it'll work. Just if you go with one, make sure you locktite the hell out of it. Not one to go with if you plan on taking it on and off if the need arises.
