Thread: Anyone used a supressed/moderated shotgun?

The design that I have developed has extensive porting of the barrel, so you just use STANDARD off the shelf ammo (2 1/2 or 3"), it internally drops the speed to below the speed of sound and other internal features suppress the sound further. The report is somewhat akin to what you hear from a well suppressed 22 running on subsonic ammo.

I did develop the same with a 12G and whilst it worked well was just not cost effective to produce.

We have a supply issue with the Optimas and Eternals that I was using so are currently in the process of developing a new model based on the Rossi Montenegro which should sorted early in the New year.

That's really interesting, I would have thought a 12g would have been a lot more cost effective overall considering the relative differences in availability and price for .410 and 12g guns and ammo...

for him not for the end user
Ie cost of it would be higher

I had one of the FSS 410s shown to me by a friend and yea they are tons quieter than my subsoinic 77/44 which is very similar in bore size

it was like a long 22lr sub sound like wooosh

Yeah I get that, but even if the suppressed 12g is more expensive to buy overall it would work out cheaper very quickly. Some places don't appear to even stock .410 ammo of any sort now.

I believe there is SMALL market for a long over barrel suppressor that is threaded onto existing barrel...the problem is.....it has to be timed and offset of sight picture will be all to hell...and would require the origonal barrel to be ported like a swiss cheese....so it would only be usable with suppressor fitted,expence would be not a lot less than buying one already made.

In theory yes, but I am still in the development stage with the Rossi and making production tooling etc. If the Rossi you have is not a current Montenegro (preferably with the 22" barrel) it is likely cheaper for me to supply a completely new gun than try to rework an old one.

If you send me your details, I can put you on the list to contact when we get top that stage fssprecision@gmail.com

Thanks

You find that as the bore size and gas volume increases the suppressor must increase accordingly, as I say I got one to work with standard 3" shells and it was QUIET but the gun weighed in at over 4KG and was really big. There really is a significant amount of work to do to really suppress a shotgun, just an end can does not achieve the level of suppression that I am happy with.

As I mention and is confirmed buy one of the guys on here, I aim to get similar suppression that you find with a suppressed 22 on subs BUT using standard off the shelf high velocity ammo.

Cheers

Give greg call at maniatis gunsmiths he has successfully made 12ga and .410 I have a .410 that I have used for pest control over the years. Great for lifestyle blocks.

Could be wrong but I dont think you can use for Game hunting.
