I've seen the ASA website, but I can't find anything that backs it up on a Massachusetts website. Any MA hunters here that have a link to the regs? Thanks.
The hunting regs list approved methods for taking game. If airguns aren't on the list they aren't approved. Be carefull with the silencers too as there are illegal in the taking of game. Always er on the side of caution. Having a few hundred dollar fire arm taken away for breaking the rules would suck. Imagine it being your few thousand dollar rig instead. All I'm saying is be diligent and get permission, or denial in writing.
