Anybody have any experience with suppressing a 91/30? Been looking into doing it after I get back stateside but can't really find any 1st hand knowledge about it. I'm not sure if I want to just buy one or just do the Form 1(?) and try my hand at making one, so knowledge of any kind would be much appreciated.
 
I've seen it on YouTube. Suppressed as well as any other .30cal rifle shooting supersonics. The long barrel helps with gasses. Remember that all milsurp ammo is corrosive, though. If you intend on using it then you'll want the can to be user-serviceable.
 
a) What would be the fun of a Mosin if you suppressed the thunder?

b) Wouldn't the muzzle flash of a Mosin just burn up the suppressor?;)
 
54R and 06 are pretty much identical in power and any 30cal can rated for 308 and 06 will handle this cartridge but the corrosive surplus ammo will eat the can away so you would be limited to using modern ammo like wolf or bear etc if you dont want to clean out your can everytime you shoot it

The YHM 762 cans and the Liberty Freedom and Victory are good to go

No supersonic cartridge suppresses well because of the sonic boom created by the bullet and the m44 should be fine suppressed

I'd recommend a quality can made of Platinum-Iridium for this application ;). Cool idea, though; probably more handy than a Mosin with the spike affixed, too. Just learn to kick the bolt open very quietly (sans cursing) so you don't give away your position :D

The plan was to load up some subsonics or at the least some reduced velocity rounds, thanks for the recommendations for a few different cans, this will be my first project involving a suppressor.
 
Would it be more beneficial to leave the barrel at or close to the original length, or to cut it down to say 16 1/2 inches?
 
I'd leave it original. If you don't like it, you can always saw it off and rethread it later. If you cut it off first, it would be hard to stretch it back.

Pre-WW I, it was planned to issue a few Springfields with Maxim Silencers to each outfit. Reduced recoil and muffled muzzle blast would help the sharpshooter.
 
I wouldn't think corrosive ammo would be a big deal. Just get a stainless steel can, rinse water through it real well after shooting and then heat it up any number of ways to cause evaporation. I'd probably use DI water but isn't really necessary. I would imagine the former Soviet Bloc countries have been shooting corrosive ammo through suppressed weapons for a while now.

There is plenty of boom left over when shooting any high powered rifle with a silencer. Do you shoot your Mosin without hearing protection? Shooting my 308 with 26 dB ear muffs or a 30 dB silencer is not much different, still kind of noisy to me. The main differences are that the silencer adds weight and the noise is reduced for everyone.

All high powered rifle cartridges can be effectively suppressed by an appropriate silencer. Silencers only suppress muzzle blast noise and do nothing for action, bullet flight and impact noise. Saying that supersonic cartridges do not suppress well is like saying a car muffler does not work well because you still have wind, tire and transmission noise.

Why on earth would anyone ever wish to suppress such a thing! ;)
 
Here's a picture of what the issued Mosin/Nagant M1891/30 with a PBS ("priborum dlya besschumnoy strelbu"/"device for silent shooting") looked like.

I may have read about it somewhere. If I'm not mistaken, doesn't it lock around the front sight the same way as the bayonet does?
 
The pictured ones are dummies ("maket"), but some of my books show the internals on these, and there's no reason a live one couldn't be built for US sales. In Russian use, they were also issued with S40 (sometimes denoted as US40) reduced-velocity ammunition, having an LPS jacketed bullet painted all green, and a velocity of around 330 metres/second (just over 1000 fps).

That looks like something I would want on my Mosin Nagant. I am not interested in classic internals, but I would love to make one that looks like the classic version on an ATF form 1.

Got any good external measurements for us? Thanks.

No external measurements, sorry, but Semyon Fedoseyev has written several books on Russian military stuff, and his "Oruzhie Spetznaz"/"Special-purpose Weapons" shows a drawing cut-away of this suppressor, with two thick rubber wipes, a central expansion chamber, and an initial diversion chamber that forces the gas into a bell-shaped chamber before it's bled off.

I wonder how effective this design is, well not the internal design I have a pretty good idea what that sounds like, but the "twist on" mounting system, I would bet that there is a significant amount of noise from here. Anybody who owns more than 1 91/30 will tell you one bayonet will drop right onto one gun and on another you can get it on but it takes 3 good men and a mule to remove it.
 
That PBS is pretty sick. I wonder what difference it would make if you were to make one with baffles instead of wipes? I'm a sucker for historical weapons and their accessories, so now I'm pretty curious about how effectively the Mosin/PBS combo was employed in WWII

On another forum there is this picture and the caption says something along the lines of Russian special forces weapons.

and the German version

Interesting, mp; the middle drawing shows the Mosin suppressor designated as the "S-40" pattern, with the abbreviation "Gl" ("glu****elya"/"silencer").

Note: interesting; I hadn't realized there's a profanity filter, but the missing letters in the Russian word for silencer are a common word for faeces.

Edit to add: These non-functional suppressors are available from bramit.ru, with the S-40 currently listed at 3000 rubles (92 US dollars); http://www.bramit.ru/-/11-glu****el-dlja-vintovki-mosina-.html
