I didn’t know what this stuff was called when i ordered a chunk off Amazon for @ $14 delivered, but as near as I can tell it is
silicone/fiberglass sleeve.
So far it is not pretty, but it is cheap, doesn’t weigh much, stretches, and it seems to work fairly well.
You can feel heat through it(upper end of what i could stand to hang on to for several seconds), but neither me, the paracord cinching, or the fiberglass inner has been damaged.
I’ll try to remember to take a thermometer along to get something more solid than “kinda feels like”, but so far this seems promising.
I just avoid shooting suppressed as much as possible. I’m taking my YHM R9 every weekend and have set up my A2 flash hiders for low torque removal so I can add the can if peer pressure calls for it.
I think suppressed rimfire is almost entirely a positive since there’s not much weight added, probably increases reliability, no 3rd degree burn risk without trying, and even fairly cheap models still work fairly well.
I lean towards centerfire rifle usually being more beneficial than not if the can weight/length is kept down so it doesn’t really screw up the handling. I think being able to mitigate gas to the face is a must on being able to enjoy a suppresed AR.
I’m still on the fence on ever getting a centerfire pistol suppressor. This guy goes in to more detail, but his point about not really being able to use it as a pistol due to the holster issue is a big catch to me.
Nothing earth shattering, but the low cost/weight/bulk appears to be a good deal to reduce the chance of incidental contact causing a burn.
10rds dump then about 30 seconds to let the wrap heat up, slid the wrap forward to measure metal, slid it back to warm up again, and wrap measured 2 to 3 minutes after firing.
I’m surprised at how many guys on Glocktalk and other forums recommend a rimfire can to suppressor new guys. The baffle gunk and lack of actual power in the rimfire round are deal breakers. We have them and have shot them, but in the end it’s just dickin around.
To me, why suppress something you wouldn’t fight with?
Cheap practice, small game hunting, and things like that.
It also gets multiple shots truly hearing safe.
The crud build up is a pain. If the BS regulation ever completely ends, a low cost 3D printed rimfire can that lasts a few thousand rounds before tossing would be nice.
9mm sub sonic is my favorite because it mimics a real caliber in all of it’s gutless glory. I lost interest in rimfire years ago when people were hoarding it for God knows what reason.
I agree though. You should be able to buy a $50 disposable rimfire can each year.
More pleasant range experience with newbies or kids indoors or out. I suppress my 10/22’s or other 22 rifles and just got a 22/45 with a dot, I’ll do the same.
9mm and up pistol I almost never shoot suppressed, but all my long guns or PCC are always suppressed.
Really though a 10/22 with subsonic ammo is barely louder than suppressed. For newbies and kids, I honestly like a little bark because to kids a super quiet firearm can seem like there’s no danger. Not ALL kids, but a suppressed rimfire can seem like a toy or paintball gun because it’s so quiet.
Harbor freight sells or used to sell these black felt-like heat shields for soldering copper pipes inside a house wall. I have had a butane torch on those for quite some time and all I ever saw were a few glowing threads. Perhaps the two combined might work well. I’ve never seen that product you posted. I also can’t find a link to what I am talking about. They are cheap, about 12” square. Maybe I got them at HD and not HF. They work well for their intended use. $15 each at HD, found a link. https://www.homedepot.com/p/Oatey-9-in-x-12-in-Hands-Free-Solder-Heat-Shield-2-Pack-314002-1/313787820 they are very light as well. Never tried to cut through one I assume heavy scissors will work.
I had never seen this silicone fiberglass stuff before either. I think i have 3’ coming from ebay since the Amazon seller doesn’t appear to be restocking.
I can’t see the texture on the Home Depot item. Does it look like the stuff in this picture?
but I would guess it’s more like 1/8" thick. I recall these getting bad reviews for suppressor use, but i don’t recall the specifics on why. 3/8" thick would be a whole different ball game.
I got it for a rail cover and it works well for that.
OK, I just measured one I have. Had it for years and the felt is kinda puffed up so I measured from gromet surface to opposite grommet surface. 1/4” Now as it sits these grommet surfaces sit slightly below felt surfaces as the grommets compress the fabric a bit. So accounting that perhaps the fabric has expanded some I would say it is at least 1/4” thick. The thinnest spot I could find of just fabric also came out at 1/4”.
The fabric compresses very easily though. Unlike most felt that if stacked i retains a good deal of it’s thickness, This stuff, at least what I have, compresses very easily.
Also you know of this as well but you can buy silicon sheets to solder on. They are cheap and I think can take just over 900 deg F.
The one I have is about 8 x 10 x 1/8”. The one’s on Amazon are kinda fancy to put parts in and such. Even those can be had for under $15. I have no idea where I got mine. It’s just white sheet goods.
The stuff in the original post is part of one of Pappabear’s can covers. I saw it yesterday. The material covering it slips back a bit and exposes the rubbery part. I knew I’d seen that somewhere.
