Beeman P17 LDC

[brewbear]

I was perusing the offerings on the Buck-Rail website and noticed a few LDC offerings for the Daisy pistols. I always thought that my Beeman P17s could possibly benefit from such a nice addition but as of now, such a thing does not exist. I contacted Buck-Rail this morning and asked them if such a thing is possible. I will keep you folks up to date with their reply.

I found the 3D printer file for one on thingverse and made one it does work quite well but any bump and your clipping its a friction fit in the front opening so rather imprecise.

That is good to know, thank you. I have a 3D printer still in the box, time is in very, very short supply for me right now.

Beyond the barrel, the Beeman P17 structure offers a nice tube of 19mm long and 10mm bore. I figured I could use it for a DIY LDC of my own.
I succeeded with a small one  I have to remove before cocking, but I got used to it and it's efficient enough. The biger one is more efficient but its tube has a 9.7mm outer diameter so I had to cure this with some Teflon tape, which isn't satisfying a solution at all.
Considering the noise, I measured it at 100.9Db without LDC, approx 90Db with the small one and around 88 with the big one ; all this without any pellet, which means it's way more efficient when shooting.
Took some pics this morning.
As for the LDC itself it's a small PVC tube with 2 washers, one on each end,  stuck with epoxy glue, and some felt inside. I think it would break of even blow away with anything more powerful than the Beeman P17 . It has no influence on accuracy.

 Ives is on to something, I added a longer barrel to the p-17 on the middle right. Using a Daisy 880 barrel, and then carefully measured and cut the Daisy barrel shroud to fit, it matched the P-17 opening, similar to what Ives did, with metal tube that slips over the barrel and the opening fit to match. (Sorry, but you are not allowed to access the gallery)
 In my case I was then able to use a Daisy 880 slip on LDC.

Outstanding, James! This is is a much smarter way to go, at another level. Installing a threaded barrel, long enough so that you don't have to remove the LDC with every shot and here you're ! LDC or not, I guess you gained some power, didn't you ?
Didn't know Daisy slip-on LDCs existed.

The B&R for the Daisy 415 works quite well….gun is pretty accurate out to 20 feet with Avanti BB’s…good luck

With a longer barrel maybe the LDC for the Crosman barrels would fit?
No?
Turn the end of the barrel down on a lathe??

The issue is the LDC (if long enough) will hit the trigger guard when cocking.  I believe there is a mod to alleviate that problem, but I haven't tried it.  The "LDC" I made is too short to do much quieting, but it does fit when the P17 is cocked.  Mine is a P-22, made from a 1322 barrel, but same idea.  Made it using WyoMan's excellent threads on P-17's.  If there was a quick detach it could work better.  Just not much room to work with.

If you convert the safety to manual then you can hold the trigger in while cocking and release it when the moderator hits the trigger guard. Slightly shorter stroke, but a longer barrel can make up the difference in fps.

Thanks for the idea. 

Was also thinking of making a quick(er) detach for a moderator.  Maybe along the lines of a multi-start thread.  Printing a moderator with the multi-start thread would be the easy part.  I designed a 5 start thread.  That means, 5x less rotations of the thread until it is tight.  Have to figure out how to make the barrel adapter (on my lathe).  It would be a 5 start 1/2"-20.  An individual lead would be 4 threads per inch.  So it would look like a normal 1/2-20, but a 1/2-20 won't fit.  The advantage is the device will come on and off in less time.  The disadvantage is making the multi-start adapter.
