Not exactly what it was supposed to be. - Troy SOCC Low Profile BattleRail M-LOK PDW 7.6 Inch

The hand rail i received did not have the protruding lockup at the receiver like it should. I'm sure this is a redesign to make this rail work with upper receivers other than the matching troy billet upper receiver i bought to go with this rail. It doesn't have anything to keep the rail from rotating out of place other than the castle nut clamps. They discontinued this model by the way. Also there isn't anti rotation feature on the qd spot on the rail. It's the first time I've purchased troy products and I don't think I will in the future. There are better options like MWI, which are much better functionality and are better quality. I can't recommend this product or troy. Disappointed
