    Default How to quiet an SOS

    With the old style STS we always had the option of changing out the rubber stopper to something that was quieter ie..the MacDaddy or Simms. Now with the SOS, I don't forsee any aftermarket companies making a replacement that may help reduce the "thunk" so I used some foam rubber weather stripping with self adhesive backing behind the SOS. It cut the noise level of the sos by a good 50%.

    Archerx7, that's very usefull info, will try that. Maybe you should inform Martin, I actually took my SOS off and attached a lower suppressor with good results. The noise with the SOS, was very much a higher frequency kind of a 'slap'. I can understand how the piece of foam would deaden the 'slapping' sound. Good thinking 99.

    I too decided to try this on my modified Firecat. Thanks for the tip. I haven't had a chance to shoot it since doing this but hope the weather will cooperate enough this weekend to do so. Once I do I'll report my findings here.

    I had to replace the rubber on my Onza last weekend because it was cracked. That will make the stop last longer I believe. Great idea I'll have to try it out.

    I got a chance to shoot with the weather strip piece installed in the SOS and was pleasantly surprised to find that it does add a little quietness to the shot. So, for me it worked. And as boothill thought too, I think this could help extend the life of the SOS rubber piece since it won't be stretched as much. This is definitely something that deserves to be a sticky.
