I just received my PSA 'premium' barreled upper with a Midwest Industries free float handguard/rail installed. The first thing I noticed is that the handguard was not tight to the receiver and could wiggle a couple degree's in either direction (ie it seems to be finger-loose and rotation is only stopped by the gas tube). The handguard is not slipping on the barrel nut, rather the barrel nut itself is moving. Is this normal or did they not get the barrel nut tightened down before installing the gas tube? I assume the latter, but want another opinion before complaining to PSA. Thanks.
