Lvl 10 reg. piston replacement

[msubdawgs]

I am having the same problem as cwuchu with the reg piston.
Is there a difference in the high pressure reg. piston?
Just wondering which one to replace, don't want to buy the wrong part. Thanks.

The difference between the high pressure reg piston and the older pistons are that the high pressure piston will vent at higher pressures.

They look the exact same. There is only one reg piston in the valve assembly. You have to unscrew the back half of the reg (where the spring pack is) to get at it.

I had a similar issue when I got my used E-Mag bout two years ago. The Mag refused to chrono at a reasonable level (275 or so) without leaking out of the back of the reg when I turned up the velocity. Ordering a new reg piston from AGD cleared it right up.
