Good but needs tweaking - AIM Sports Inc AR10/LR308 .308 Keymod Handguard

This is a nice overall handguard, matches the height of my LFA upper which is high , my issue with this thing is the barrel nut that comes with it, which has 2 grooves that match the locking bolts of the rail, said grooves do not align with the rail holes rendering the whole rail unusable..unless you grind them down thus making the very existence of the grooves pointless..so basically idk what specific brand of upper this rail is supposed to be made for, i guess i couldve lapped the upper receiver but why would you want to get in the hassle of even doing that?
price is very reasonable, finish if very nice...install and fit is basically a thing to be considered, id buy it again just cause of the price point, but be prepared to having to work on it.
