What have people been doing to adjust the length of the brass piston derlin hanging out if you try to install them the way they are the adjustment screw hangs out to far
Brass piston length for amp regs
- Thread starter Airgunmann
- Start date
You would think they could make them to the correct length when I ordered one from Martin for my raw it was correct length

Great it sure is accurate stretched it out to a 100 yards could hit a pop can at least 75 percent of the time depending on the wind I got it set at 34 gr jsb running 895 fps with 60 gram hammer still using peek valve also

The derlin on the fx brass piston was out .030 more than the originals so that's how much I trimmed off them for the M3
