Factory polymer grips on M4 and M16 GBB rifles are fine until you don't want them to be. The ACW CNC Skeletonized grip replaces that stock polymer with solid CNC-machined metal. Simple part, clean build: the skeletonized cutout saves weight without sacrificing strength, and it fits tight — no flex or wobble when you're shouldering the rifle.
Standard M4/M16 mounting pattern, anodized black, metal construction. Just swap it in where the existing grip sits and you're done. If your stock rides close enough to the receiver that a thicker grip would interfere, measure before you commit. Some PDW-style stocks leave room; others are tight. If it doesn't fit, it goes back on — no risk to the tube.
What it isn't. This is a cosmetic and tactile upgrade, not a performance mod. It doesn't change velocity, rate of fire, or ergonomics in any measurable way. If you're looking for an angled grip, a folding stock, or a shorter buffer tube, this isn't it.
Includes one pistol grip.
