"I installed this in my G&G Combat Machine CM16 Raider and the accuracy is of the charts. I paired with a Madbull Shark bucking and nub and it's a LASER BEAM!

Warning: This hopup will not fit into krytacs, the clip is too big and it will cause it so no mags will feed. Youre better off sticking with the stock Krytac chamber or a prowin!
