VFC Has their own Specification for their Gas Blowback Rifle. There has a number of players who doesn't know and Now SIXmm has chosen those out for you and easier to buy.
Finally!! A hopup that fits perfectly!. It's so hard to find parts and cheap Hopup for my well L96. Luckily i bought this hopup here and fixed my accuracy!.
I Love it so much! Its perfect! I looks so good on my Cyma Mp5 also works on my H&K MP5 but need to modify it a lil bit so that it'll click and stay in placed! Will order again!
