Idea, need input
Okay- so I’ve got one of these “Solvent Trap” kits that’s pretty much useless to me now. So my question is: How well would firearm type baffles work with airguns? Again, this is SPECIFICALLY FOR AIRGUNS, NOT FIREARMS. Here’s a pic of the baffle I’m talking about:
I have an idea for a .30 airgun LDC, I have this kit that I’m not using, so the gears got turning. I’m just not sure how effective these baffles would be. The solvent trap is a 1.375″ tube that’s 8″ long, with 7 of these baffles. It’s not a lot of volume, but something of this size is designed for suppressed 9mm pistols and those sound great suppressed. I’m not sure if the same design would be quite as effective w/airguns though. I’ve heard/read that K baffles are definitely not as effective w/air, but Airforce uses them, it’s what their sound loc baffles are. But what about this type of baffle? I wonder if these would be better. Also, more and more LDC cores are being put out by airgun manufacturers that look eerily similar to powderburner designs. But again, what do you guys think?
AGAIN, THIS IS FOR AN AIRGUN MODERATOR, NOT FOR A FIREARM!!!!!

Like the idea of the air stripper! Never gave that a thought when designing suppressors. 1.875” ID. Should be plenty big to capture the air volume of the .357 Texan.
The book I am reading now is all about wet suppressors and have done them before for .22lr’s. capturing the heat is part of the factor in quieting a powder burner even in .22lr. I know heat is not an issue for Airgun’s but I will tell you that water based gels work well in dampening noise too! They do stay in place once spun on a lathe and an oversized patch is run in to make sure you have no obstructions. The book also mentions cooper(non-rusting) scouring pad as a great heatsink for the expansion chamber and holding water based gels.
I still have a variable sized air stripper, .177 – .41 caliber I may have to modify……
Yes I had a manufacturing license to make suppressors!
I had another thought- Bear with me, it’s hard to get my ideas out when I get (at least I think so) a good idea…
I know I’m using a 2″ O.D. tube, and the longest I can get one (manufactured, not handmade) is 12″.
I want to set this rifle up as short as possible w/o giving up barrel length…
So this means that I’ll have to vent some air behind the muzzle, as well as have some sort of baffling in front of the muzzle…
I’ll use the muzzle as the “half-way” point, and vent 6″ to the rear and 6″ forward…
I’ll use this design as my “blast baffle”/air stripper/shroud support, that allows the air to flow to the rear of the LDC:
I’ll also drill vent holes near the LDC mount to vent the air. Tony and Doug do this, and their LDC’s are VERY effective! Size and number is the difference, and I’ll not give that away- I’m not sure how Doug would feel about that.
I’m not sure how I’ll baffle the front, but I know it’ll be a monocore. I’m not messing with individual baffles… It’s just too close to powderburner territory, and I don’t want to go there. It looks like that air stripper is 3″ long, so I’ll only have a small amount of room in front of the shroud for a monocore… I’ll play with the design when the time comes… Besides, with the .357, I’m only looking to take out the crack, not make it sound like a suppressed 12 fpe .22. I think I’ll be happy with this.
Anyhoo, I guess I should re-name this thread “The .357 Texan LDC” :biggrinn: This is where I’m at for now, since I won’t even begin to make anything until after I have a .357 Texan, and have the new barrel and 1 piece barrel bushing/LDC mount machined…
I’ll revisit the 2″ O.D. LDC when I get around to my .357 Texan. I’m trying to make this .30 condor as small as possible, so it’s my first focus. Plus, I already have the .30 condor to modify. I don’t yet have a Texan. :biggrinn:
yessir!
Nice work! CNC machined?
Here’s a pic of the end cap:
Not sure how much of an effect the radial cone end cap will have on the sound level. I decided to get the 6.5″ L 1.5″ O.D. tube. I wonder how quiet this .30 will be?
will do!!
Pictures when you get a chance!
Will do the same when I start mine.
Well, I can’t get the muzzle end threaded for 1/2-28 because threads are scary… No matter! I wasn’t too keen on spending more money on that experiment!
I’ve decided to go with a 1.5″ O.D. tube, 1.37″ I.D. The 1 piece barrel bushing/shroud mount will be the same. The shroud’s end cap will have a radial cone on the inside.
Not sure at this point how to stuff it. Or if I’m going to stuff it at all. I want to try to put a 1″ spacer between the muzzle and the first baffle. First baffle is a radial cone, then either empty air between the first baffle and the end cap, or something… Time will tell I guess.
6″ long and 1.250 OD max. Brake will be 1″ OD and 1 1/2″ long. This will work with any rifle with 1/2 X 28 threads.
Yeah, in your position, I can see that being difficult…
But I’ve got 1.75″+ ID to work with… I think I’m going to go the full 12″ length. 2″ OD… Hmmmm…
I have been working on an integrated brake and can. Trying to make it small enough to be useable is the hard part.
So here’s a thought:
Powderburner suppressors sometimes use a compensator as both the suppressor mount and as the blast baffle. I’ve now talked to two guys who run empty cans (or mostly empty). What if I literally took a page out of the powderburner’s page and used a muzzle brake in addition to the empty can? What are y’all’s thoughts? All I’d have to do is thread the barrel (I should have enough meat for that) for the muzzle brake…
Type of muzzle brakes I’m talking about:
So I’ve decided that I’m definitely going with a 2″ OD tube for my LDC for the .30 bullpup. Basically it’s a Napa 4003 fuel filter. Again, this is FOR AIRGUN USE ONLY. What are your thoughts on:
A) Using it as is with very minor changes (end cap and such).
B) Run it with a 1″-2″ blast section, one or two baffles and mostly empty.
I’d like the .30 to be a backyard friendly 60+ fpe bullpup. Thoughts?
Here’s a pic of what I’ll be using, and the filter element:

Holy cow, You guys keep on and doing your stuff,
I am a little envies I do not have the machines for this stuff,
The gel in the LDC is going to be the way to go,
I think it will be the next wave of the very well built LDC.
