Try putting some oil (a lot of oil, mags love oil) in the ASA and dry firing it about 30 times. If that doesn't work, get a chrono and turn down the velocity. If you're still leaking while shooting under 300 FPS, THEN, you have a problem!

If you were (unlikely but possible) still leaking, you may need a new regulator piston. (THIS PART FOR A CLASSIC/MINIMAG VALVE: store.airgundesignsusa.com/index.cfm?fuseaction=catalog.prodInfo&productID=30 &categoryID=18)

There is an oring on the valve piston. It needs to be replaced.

Or maybe it is the main seal.

In any case, a seal has failed and need replacin'.

Sometimes you just need to degas, remove the velocity adjuster to get to the spring pack, and wipe down the sealing face at the front of the assembly. Slather in grease, make sure there's no dirt, and slap it back in.
