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. :cool:

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.

Thanks a million.................:D

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.

What size weather strip did you use?

I used it on both my FC400 and my Onza 3. Made a noticeable difference in both. I used 1/2 inch weatherstripping, and just cut it down to size. Word of advice, take one side of the SOS rubber off before installing the foam. Makes it alot easier.

What I used was the 3/8" wide by 3/16" thick made by frost king, picked it up at lowes last fall for around our doors and had several feet left over. I cut the 1st strip long enough to form a half circle inside the sos bracket and the 2nd layer just long enough to fill in. The thickness worked out so it just touches the back of the sos.

Do you think it will help with the string cutting the rubber?

Not sure, but it should help extend the life of the sos since it can't travel quite as far into the bracket. I think that the couple people on here that have had an sos tear may have either gotten a bad sos or possibly may have an issue with the bracket itself, maybe a sharp edge left from the molding process ?
