endcap venting
Here’s a weird one… Has anyone made a vented endcap to go along with a vented bushing on the long barreled .257? I was just thinking that if we opened up more space rearward, maybe there would be more quieting going on… Thoughts?

For the .30, true. But for the .22 I could use one LDC for two carbines, but since each will be in their own kit, I’ll be going with 2 LDC’s for the two rifles.
If a larger OD tube and threads are used it could still be vented into the frame of the gun, but more often than not it makes the build more complicated and more time consuming to make. The only thing is, I like to make them, when possible, so that the LDC can be used on other air guns, building a special like this would pretty much restrict it to the one gun, Neil.
Yeah, I thought about that too… I wish there was a way to do both! But, I’m not sure there is. I need the shroud to come off for small packing. The .30 only has a 12″ barrel, and it’s only using a standard Talon valve, in a Talon frame. No other mods… Other than what’s needed to be done to fit the barrel of course. It shouldn’t be that bad. I just need to take out most of the bark. Not all of it. The .22 LDC I’ll need however… 😈 😆 Oh- almost forgot, I’ll be needing another .22 one for my Mrod project too… 😆 That’s three I’ll be getting from you Neil!
The threaded end cap I made was for a Condor with the long barrel, so the threads had to be pretty large and the shroud threads cut to match. I tried to tell my customer it would really effect venting to the frame of the gun but he did not care, he wanted his shroud so he could unscrew it, your wish is my command, Neil.

Ahh yes, the infamous and rare Hawaiian Asshole? I remember that whole incident.
@Wingman: I think that’s the type of adapter that Metalman makes!! 😀 Am I right Metalman?
I’m not even sure how something like what I’m thinking about would be made, honestly. I’m thinking of an end cap (or adapter?) That would not only allow mounting an LDC, but also allow venting back into the frame. The LDC would have to be special too, because the LDC would need to be made to take advantage of said end cap/adapter. Is this even making any sense? I hate having idea’s, and not be able to describe whats in my head… 😡
EDIT: Metalman: I’m going to need one of your threaded adapters and a LDC for a .30 one of these days! I’ve got a compact .30 I’m working on, and she’s gonna BARK!!!
I made a threaded one for my .25 too, no need to vent between the shroud and front can if your barrel is shorter than the std frame/shroud meaning the pellet has to jump a void before it exits the factory end cap into the external suppressor but if your barrel extends out of the factory shroud, anything you put in front of it would definitely benefit from venting rearward into the frame/shroud through a removed or modified end cap.
I made a threaded end cap for a customer that replaced the factory end cap,It slid into the frame and was threaded to accept the shroud he had me make so that he could screw it off and on when he wanted to. It had a cap to screw onto the threads and hide them when he did not want the shroud on it, Neil.
Yep, we had a member here that at one time did it, but he ghosted a few years back. As Assman well knows.

[quote=”Caboose212″]Here’s another thought- does anyone thread that area where the endcap used to be, so that a LDC isn’t held on by a grub screw or two??? I’m sure someone has… Or was it not possible before because of the weakness in the factory frame?[/]
Jim Gaska could probably do this. The threads are not all that deep. Lots of shrouds are threaded on the inside or out, for use with an LDC, they aren’t that heavy. I believe any forum machinist could do this.
Doug currently has a frame of mine that was threaded by a former member. I think it was threaded in a way that wont allow it to work, but maybe Doug can chime in if he sees this.

So aftermarket LDC’s go into the frame like the original one? Retained like the stock endcap with a small set screw? I mean, it would kind of have to be, otherwise, the vented bushing with an extension would be superfluous, seeing as no air would make it back into the frame… Okay, I see now. I’m trying to decide if I want to shroud the .257… I’m thinking on how to get maximum quieting pushing that much air…
I don’t follow. Most LDC’s do away with that part. If somehow it was retained, and connected to the LDC some how, yes, venting it so that the air blast could be directed back down the interior of the frame helps a LOT! That is how mine is done, but the original end cap is “Long Gone”. 😉

yeah- the piece that is either the “shroud” endcap on an SS, or the barrel collar on a standard Talon or Condor… endcap.

When I said other guns I mean’t different makes of guns, if it could use a 1/2 inch thread then the LDC or shroud could be used on a lot of different air guns, As a special build these would be restricted to exactly the same type of guns, so they could be used on other Condors and Talons as long as the bores match, Neil.
If you have the recessed barrel then a 1/2 inch x 20 threaded end cap is easily done, that way the LDC can also be used on other air guns you have with 1/2 inch threads.
