Recommendet Sterling bolt modifications

Up is stock Sterling bolt, down is after modification:

Mods are:
- screw velocity adjuster trough gasflow restriction
- additional guiding o-ring
- small o-ring working like shock absorber of the bolt while closing

I did this to my stock Sterling bolt (adjustable from the front) and to my Venturi Sterling bolt (adjustable from the rear). I now regret doing it back in the 90's because with a Regulator on my gun I see it was totally unnecessary.

just my .02

Started with a Splatmaster, moved onto a Nelspot 007, then came the Autocockers, then a STERLING Pump, next was a Bob Long defiant then a PM7. As of now I have 10 Sterling Pumps, 2 Phantoms for SC, a CCM SS-25, a PGP and a Sovereign 3.
