The grip needs some shaving but other than that fits great into marui and cowcow grips
Fits really well into Double Eagle and Cyma m4s
It has a plastic slide, but perfect for upgrading
fits really well into ml and tti chamber
Matte silver look, refs at the field really like it however not the best fit on the nexxspeed HopUp though and super light weight
