Homebuilt adjustable Bolt

[Frog of Peace]

So I Made this for my old Sterling Bronze.
the rear part ist glued-in because I had no tools long enough to bore and tap deep in the bolt.
O-ring ist Just to keep it from loosening.

I hope the glue is strong enough to withstand use! Should be fine though since it's manually operated. I need to do something like this for my Tigershark

Ingenious idea and it works good?

I haven't needed it yet, but it can throttle gas-flow to almost nothing, so I'm sure it will Work.
Now I can think about increasing velocity without worying about being to fast in the field. Need springs and a longer Barrel .

There are really strong glues Like loctite 638 for this, make Sure you have enough mating surface. It is easy to calculate.
You can put a pin to be Sure.
