which is 160mm in length and will give me a total of 407mm so i could get a 407 tight bore or

With the 300-310mm tightbore you'd probably be ok with the cylinder you've got already. 407mm I'm thinkin you'd likely see a decrease in muzzle velocity as the port in the cylinder releases enough air to not offset the added volume of a longer inner barrel.

just something to keep in mind.

does it have to be some anti-zombie silencer?

dang bishop, you downin man!

i didn't mean it like that, i meant is he going for a specific anti-zombie theme or was that just the silencer body type he wanted?

@ Panzer ok thanks for the thought i think my gun runs kind a high like high 300s so that might be good to slow it down but would it decrease accuracy or just speed and i assume range?
@Bishop no i just like the way those two look but really anything that is reasonably priced any suggestions?

ah got ya

It'll effect velocity, which to an extent does go hand in hand with range. Your accuracy won't suffer though.

ok i can see that so i assume that its all about how i want the gun to look from here huh lol.
