TM M92F BB Rolling out
 

Hay guys, I have a M92F with Guarder upgrades, a hammer spring and a PDI piston head upgrade from stock. My issue with the gun is that sometimes bb rolls out, or double shoot. Once in awhile it kind of almost goes auto? For the Guarder sldie upgrade, you're suppose to modify this part:

I didnt modify the part shown...not sure if that would affect it?

Huh strange, it seems it was the 150% spring causing the problem. I guess when the slide racks bad, the force going back to the front must lodge the BB a little further up causing the BB to go over the hop-up.

Switched back to the stock spring and the slide has a hard time locking back with an empty mag due to the slide being heavier :(

Now what can I do to get the 150% working without it pushing the BB to far out? Should I sand the nozzle a wee bit, or cut the spring a little?
