What you need :

Something you'd want to know CrimeinHell - Putting .25g bbs with top gas @ 350 fps, with .01 247mm PDI inner barrel in silencer - shots were chrono'd and group'd today. Getting more than 100 shots of one 3 second fill of a 26 rd. maruzen mag. because of aluminum bolt.


Thee sacred PDI .01 (straightened and stabilized with 2 mere o-rings)

[CrimeINhell]

if I understand you can shot more than 100 bbs with a 26 rnd mag ?

in my case i can shot 125 bbs with a 50 rnds mag (in single shot) and shot at 330 FPS with 0.2 but I've got a twisted barrel (leakier than a precision one) and I weighed down the bolt to decrease the rate of fire. I will try it with an other barrel this week end.

thanks for your comment

grrr pm messaging is being really stupid atm, so heres what i was trying to send to you.
hmmmm, i dont really care about gas consumption but will it increase the life span of the gun? From what i heard the part above the bolt, the black plastic where the recoil spring and guide rod go through is what breaks when used with green gas. I have been using my mp5k with no mods with green gas for a while and i see no signs of wear on it. I think i'll just purchase a hop up, how much will that be shipped to the us (in USD)?
i might be interested in the aluminum bolt in the future, but for now i dont have the money to get one and it doesn't seem nessicary at this point in time.
What is your paypal?
Also what length silencer is that and what is the threading on it? it hides the barrel nicely.
