22 time capsule silencer

[wired]

Kind of interesting. This is a Cobray or RPB silencer that I built with a new tube. All NOS parts. Ive never seen one like it but I have like 20 of the kits. . It was called an AK 22 silencer when they were developed for the Squire Bingam 22 cal AK. Those things were butt ugly and only somewhat superficially resembled a real AK but 45 years ago you didn't have a lot of choices and they were convertible to FA.. . The threading was 1/2-20 and these silencers are as well. I ended up with all the MAC/Cobray/RPB etc parts and some of it is quite odd. I'm sending this one into Otter Creek for testing just to see what it will do . Making a 1/2-20 to 1/2-28 adapter tomorrow.

Lots of eyelets, lots of wipes. lots of volume. Thats how silencers were back in the day.

That’s pretty wild! Thanks for sharing and looking forward to see how it meters.

Crazy goofy idea, but can they meter it twice? Once at room temp and once after being buried in dry ice for a while. Thinking that the mass of the eyelets is to cool the combustion gas, so give it a hand. Not worth doing if it costs anything, just curious.

Might wear my welcome out with that request

You mentioned the eyelets before but I must have missed the part that said they're actually used in the silencers. I thought they were just random crap that came with the other parts. 😆

They are actual OEM MAC silencer parts

No lie, Bwana! John Norrell also packed brass shoelace eyelets around the ported barrels of his integrally suppressed Ruger .22LR pistols, as well as his Ruger and Marlin rifles.

I was allowed to disassemble a Norrell Ruger Mark II in 1989, and after removing the two-pin-hole front cap and a series of nicely-machined, petite “M” baffles (and a small spacer, IIRC), I could clearly see a batch of tiny, sooty, top hat-like things packed down around the barrel inside the tube. It was very weird; I had _zero_ idea what I was looking at. They might as well have been moon rocks. I think I asked the shop owner, Craig, and he told me what they were. I had assumed Norrell used copper mesh like Doc Dater at AWC did in his RST and later Mk2 Ultra integrals.

I had the opportunity to speak to Mr. Norrell a couple of times on the phone. He said he liked the brass eyelets because they were readily available in quantity, wouldn’t melt, could hold a lot of carbon & combustion product before needing repacking, and created massively irregular pathways for the gases to expend energy and cool before escaping back out into the barrel.

He sent me a very gray photocopy of his of then-current price list. I’ve still got it in a file somewhere. I’ll see if I can I scan it and post it up here. It’s a fascinating look back into the past.

We really do live in the Golden Age today.

They are the same shape as raschig rings in a wet scrubber and do essentially the same thing. Lots of surface area to promote cooling and airflow. They work and work well but they are consumable.

I have a few cans from the 80s that were built this way. Re packed a few and the old ones came out a a 1 piece mass of brass, carbon and lead. Was too funny.

I build a lot of 22 integral suppressed guns and I absolutely refuse to do ported barrels because of that scenario in relatively low round count guns

 

[NCLivingBrit]

I didn't have any idea folks used those eyelets as suppressor "baffles". Makes sense once I thought about it, dirt cheap to replace, lots of twisty channels to slow the gas...

 

[wired]

There not really baffles per se. More like Raschig rings in wet scrubbers. Lots of surface area and they absorb heat quickly . The whole thing, like all MAC cans is just a big heat sink. Its a quite a bit different design than modern reactive baffles that use redirected expanding gases to impede laminar airflow.

I put a few rounds through that one the other day. Its as quiet as youd expect a silencer of that girth to be. Ive got enough stuff to make 20 or so of them if I punch out some more wipes.
