Fx impact and power plenum
- Thread starter spyde82

Here's the porting work I do to really start the air flowing smoothly into the ports. Porting was the biggest single thing that I did that yielded the biggest percentage of gains in FPS. Hamer weight was a close second. I can get well over 1,000 fps with .30 Cal 50.15 grain JSB's and I haven't put on additional plenum volume to gain these speeds, though I need to because my shot count sucks.

I have the mk2 shooting the 34s 910fps req 125bar, 74shots per fill (250)bar still a little play on hammer spring adjustment, valve stop on 3rd line
Any mods to the transfer port or the spring?
just whats in the kit

Your regulator at what pressure ?

The pressures over 170 bar will yield these speeds in the JSB's, but I don't run it that high. In the range of 157-163 bar it pushes 60 grain NSA slugs around 960 fps accurately and I'm happy with that. Shot count is low due to not having any large plenum volume on there. With more volume it would get the best of both worlds, and with lower reg pressure as well.
