Boat anchor/garbage - Ergo Grip Young Manufacturing M4 Carbine Quad Handguard Free Float

This quad rail is very heavy! It lacks proper venting to dissipate heat effectively and will burn your hands within a couple mags. The mounting system, although standard in the industry is cheap and unreliable. There's a reason most higher end manufacturers have devised a different way of mounting their rails. I would say the quality is on par with guntec or early UTG products meaning even UTG is a superior product at this point. Save your money and spend another $50 and get something that won't strip out when you tighten the set/mounting screws.
