My Classic mag works just fine, BUT .....
The sound at time of shot varies with how I squeeze trigger. Sometime marker fires with a crisp "POP", other shots a "POP HISS" ( Velocity however stays consistent )
* I know this hiss is the gas refilling the dump chamber.
But being this is a PUMP altered marker and after a shot the sear is not catching the bolt and the On/Off should not allow refilling of the dump chamber yet until fully cocked.
SO, if I am hearing a hiss right after the shot one would think the On/Off timing controlling gas refill is happening a tad premature ?
Are there SHIMS that can be fitted between the TOP o-rings and valve body that would move the rings slightly closer to pin ?
Would this not alter the timing like a longer pin would do ?
Thanks,
Scott
