The part did feel solid in hand at the time. I was afraid it would have enough bite for a secure hold.

Mine were at about 45 degree or less of an angle if I did it that way. Its keeping the nut perpendicular to the slots. I had no problems getting the nut to catch on the inside. As some of the earlier posters mentioned, it's easier if you pre-tighten the nut most of the way, then push the nuts through, hold the mlok section against the rail and tighten the allen head. Magpul uses a special nut that locks on the slot and lets you tighten it right down. I have both but M-Lok is only one to make me curse and want to remove handguard to add a rail.Then your doing it wrong.
