Incredible product! Does exactly what it is supposed to. If your RIS wobbles and you want to put on a grip, m203, or if you're just a perfectionist like me, this is a must investment for your M4 RIS.
Like a diamond, strength wise.
ZERO, I MEAN ZERO movement in rails! No hyperbole!
Gives the M4 a new look, looks more like a 416 with this on
Does not accept QD scopes! Regular sights with knobs will still work, though.
Kind of pricey at $35, but worth every penny for how well it performs.
Requires a medium size phillips head screwdriver to tighten
small pieces are easy to lose, be careful
Do not let these cons stop you from buying this item. These are petty problems that shouldn't affect your decision to buy this item.
