Tight w/extra$ - Wilson Combat AR-15 M-LOK Handguard

Bought this handguard to go with my Wilson barrel. As with other reviews I found 'slipping' handguard over barrel nut next impossible without using force. I gave up quickly because I did not wish to damage handguard. Also it would have been very difficult to line up upper picatinny rails with handguard. Finally, the finish was very thin. In fact, it was rubbed bare in high spots out of package.
With all this and no information about barrel nut size and having to purchase armorer's wrench separately I decided to return handguard. I purchased another handguard kit that came with armorer's wrench and is easier to fit over barrel nut.
Optics Planet representative was big help with this return. Thank You!
