Stormrider Moderator Again

Scared to use my heat gun for fear of damaging fill port which is only an inch away from base of moderator,what do you guys think of cutting off the moderator lengthwise with a dremel cutting disc, I desperately want to install a Hatsan air stripper? Gun is already too loud for backyard use, so what do I have to lose. Please Advise!

This is a picture of my varmint air max. Yours does not have a set screw on the bottom of the muzzle break? 
I thought the storm rider was a copy of the varmint air max.
And the schematic shows one.

as for the heat, shoot the gun empty and you should be fine. 

I’d suggest the airstripper from mike at www.tko22.com

From Websters Dictionary:

say uncle: To admit defeat and/or plead for mercy, especially in an informal physical contest of some kind. Can also be used as an imperative phrase to demand that someone give up or admit defeat. The brothers often play fought, but it was invariably the younger of the two who had to say uncle by the end. Say "uncle," and I'll let you out of this headlock!
 
Dremel - cut the piece of worthless crap off. The TKO will quiet it down, not mouse fat quiet but better than what is on it
​your barrel is not threaded and the Hatsan air stripper is threaded, they don't mix and the stripper does reduce the noise level at all
the end of the barrel has a reduced diameter of 10 mm. the barrel is 12 mm, and there is a groove around the barrel under the set screw
​so it will not just slid off
​ the barrel is inserted about an 1-1/2" into the piece of junk
