Nice fit and finish


Nice fit and finish. I did have to use a couple shims to get the barrel nut out just a little bit so the wedge nut for the handguard would sit in the groove on the barrel nut and also flush in the handguard hole.<br>The finish is real nice and has a good feel. Looks <br>Looks good on 15" barrel

Great rail


Very nice finish in the rail. Solid rail and easy installation. Fair warning if you buy one of these rails you will need shims to get the wedge to align. Other than that it's a solid rail

Nice rail.

Very nice handguard. The wedge did not quite line up when doing the assembly. I didn't use shims like the some of the other reviewers. I filed a little off the end of the dust cover pin. It was contacting the handguard when sliding it on. The rail fits really tight now. Right up against the upper. Lines up perfectly.

Solid hand guard for the price!


Very fine hand guard, easy to install!
