M-700 loud

hi guys i have an m-700 spirng airsoft sniper rifle and i was woundering if there was a way to quiet it extremely besides a mock silencer ive heard of a foam stock mod but for a vsr-10, can i do the same with my m-700? what else can i do

A mock suppressor won't do anything, and to modify to suppress can be illegal (can be=99.9% of the time)
If I remember correctly the foam stock mod would work with virtually any sniper replica. Unfortunately I am not familiar with any major tools for reducing the report of your replica.

The foam stock mod for the VSR-10 should work for any replica, the main reason it works being the fact that it minimizes the echo that the hollow stock gives. However, it would only be possible if you can open up the stock of your replica. The VSR-10 opens up real easy, which is why it is normally modded that way. Give it a shot though. See if you're able to open up the stock of your replica.

ok thank you both and im staying away from illegal
