Oh man Sean! I'd love to have a meter and really check out different brands of ammo in the Beast!

9MM integral freeze plug suppressor on bolt action Suomi M-31 SMG from parts kit.

viewtopic.php?f=2&t=79319

Any chance you are building bolt action suomi's for sale? Minus the can and with the takedown feature intact. 4473 then I can start my own form 1 integral build on one. I think it is one of the neatest parts kit builds I've seen and took a lot of vision to complete! Sorry - right now I'm about 6 to...

I so agree!

I've managed to collect about a kit and a half in parts and have most of it figured out.

However, I'm so busy building Goryunov SG-43s for customers that I don't have time to do much on my own projects right now.

That's really cool. Just out of curiosity... Wouldn't a manual side / strightpull AR be a lot easier? Instead of using the 9mm blowback bolt, modify the 223 bolt (does it even need it?) and just not use a gas system all on a side charge AR... Hmmm... I may have just cost myself a bit of money right...

The magazine feed is totally functional. I was single feeding individual rounds of different brands and loads in the video and the gun won't sit on the rest with a mag in it.

Glad to be of help!

As we say over on Weapons Guild - Knowledge not shared is knowledge lost!

If anyone has questions - I'll try to answer.

Here's the final product. I will also try to post a shooting video of it.

My whole idea with this build was to see how simple and inexpensive I could do it and still have a good final result. The cleaning issue can be taken care of by soaking and air blasting. The freeze plug issue was, again, K.I.S.S. I had some theories on suppressors and wanted to look at them in actio...

In order to keep this from being a "two stamp gun" I set screwed (into recesses) and welded the can tube to the barrel. The can tube is 16+ inches long to keep it from being a SBR. The original take down latch still works so the gun breaks down into two units. http://www.gunbuilds.com/sile...

One more shot of the locking recess design - sort of out of sequence.

Test fitting all the major parts. Note the two sets od screws in the suppressor tube. The ones near the muzzle hold the baffel stack in. Remember, the major portion of the chamber pressure has been dumped through the varrious openings in the barrel so a "blast chamber" is not really needed...

Here's a shot of the baffle stack after welding, through boring and sandblasting.

Hi All! Thanks for the kind words. I figure I have taken enough wonderful knowledge from this board that I owe a pay back.

Yes - it accepts the 36 round stick mags. 50 round coffin mags and the 72 round drums.

At the end I'll post a video or link.

Off to bed - my eyes are crossing!

More later.

Here's a shot of the drilled barrel (I added 3 more holes per row later), the un-welded stack of freeze plugs and one drilled freeze plug not in the stack yet. I used a snug fitting bolt to keep the baffles aligned during welding and then lathe bored the final size after welding. The large openings ...

Here's a rear end view showing the Suomi barrel locking lugs and the chamber end of the barrel. http://www.gunbuilds.com/silencertalk/tubeend1.jpg And the barrel out of the tube. The freeze plug shown on the barrel is an end support for the barrel and it partitions the tube into a rear reflex area a...

The basis of the suppressor is the welding of a steel tube to the original heat shroud stub end. This shroud is removable - along with the barrel on the Suomi.

This is a good strong design - but heavy as hell!

Here's a shot of the major parts being fit together. I'll spare all the other details unless someone wants them.

Here's a shot of carefully hand fitting the lockup of the lug on one side. There's another lug on the other side.

The locking lug collar was turned from round stock. The bolt handle came off of a demilled 1903 Springfield bolt. The locking lugs were 4140 and TIG welded to the collar. http://www.gunbuilds.com/silencertalk/S-bolt1-s.jpg This allows the locking lugs to rotate but the extractor and feed lips to sta...

Hi! I'm Greg Clark. I'm an 07 FFL - non SOT - and spend most of my time over on Weapons Guild. However, I got the bug to build a Form 1 suppressor and became a member here. I lurked and read a lot and then started building. After getting the Form one approved and in hand of course. :) I decided to m...

Way cool Thinwater!! I'll look for you over there.

Thanks for the additional info.

I think I had better keep this short and sweet as we are posting in a Vendor's area. I put the post here as I understand AAC is the fountainhead for the 300 BLK.

You are an 07, would you tell people how to make your product and eliminate that sale?


Actually - I do it all the time.
