Okay, here's the deal; I have umpteen breeches that all take a Crosman 7/16" size barrel. I want to build a .25 carbine on this platform. There are several sources for custom barrels but I would like a drop in. Does anyone have a recommendation? I will probably put a shroud on it, maybe a BNM breech.

25 disco, certainly not drop in.... i drilled my breech to .500 but that wasnt easy, personally id order a barrel, have it shipped to a machinist like jim gaska specifically, and have him turn down the first few inches to .435, then when u get it it will be drop in.

Hey Rob, I've got a drill press but I don't think I want to mess with trying to drill out another 1/16" in the breech. The reason I mentioned BNM is that they sell different caliber breech blocks. I've emailed them to find out what the bore size is, but haven't got an answer yet. That block would make reaming out a lot simpler.

Try Mountain Air Airguns. Roy might have a barrel made up for your needs.

Whats the best source for a 25 barrel? I can do all the machine work, so it only need be a .25 hole with rifleing.

be the places to get a good liner for a barrel.

I've used MA for .25 cal barrels. Roy is really good and is very helpful. I sent him the breeches and he then tooled LW barrels to fit.

I'm a huge fan of LW and they sell 24" .25 caliber barrels, the smallest they offer is .470" though.

Recently I did a .20 caliber conversion and was up against the same problem. Since .035 is not much to remove I just did the job by turning my drill press into a lathe. I layed it on it's side, chucked up the "crown end" (tape to protect it) and ran the other end through a hardwood block with a .470 hole in it, there was about 7" of free wheeling barrel on the other side of the block. The block was secured to my workbench.

The metal was taken off of the spinning barrel with a 6" handheld disc sander. Sounds crude but as long as you go slow and check your work with a set of digital calipers it really goes pretty well. It also helps to keep the wooden "bushing" lubed.

BTW, LW barrels are about as good and consistant as they get. Most of their 24 inchers are about $110 deliver to your door.
