Out of spec pic rail - TRYBE Defense AR-15 Extra Lightweight M-LOK Handguard w/ Cut Away Rail

Purchased this, looking for a cheap lightweight handguard for a beater pistol build. Not too thrilled with the old school style "pinch" mounting system, we've came up with better ways since this was prevalent, however should work just fine for my use. Also, finish didn't seem that great, very flat and "matte" compared other anodized aluminum parts; again though, not a deal breaker at this price point. My real problem came when I went to mount some top quality, metal back up irons. Noticed the sight was sitting off center when tightened down. On inspection, this is because the "floating" side of the attachment point (the loose clamp piece that the screw would thread in to on my sights) wasn't sitting properly under the top lip of the pic rail. Tried the same sights on the receiver itself and a couple other handguards; no issue. Also tried some polymer sights that have to slide over the rail...even with considerable force it won't slide over this out of spec pic rail. I'm not going to force it and risk damaging a set of sights that cost more than the handguard did.

If you need a cheap rail and have ZERO intention of mounting anything to the pic sections, this may be for you. Otherwise I'd steer clear. If I had realized this before I trashed the packaging it'd be going back.
