This simple design uses interchangeable barrels:http://www.spudfiles.com/forums/new-thunderpup-t14543.html
It would be easy to create a similar barrel attachment (for airsoft) using a threaded end cap with a hole drilled through it.
If you use lamp pipe, a brass or aluminum tube fits inside it and the OD is 3/8" so the lamp pipe fits inside a "hollow rod" standard size in the hardware section of Home depot
(where the angle iron, solid rods and bar stock/ short all-thread rack)
The OD of that pipe fits 1/2" copper or drilled out brass "T" so a magazine can be attached easily as well.
With the "Thunderpup" I could shoot anything from spuds or full length arrows (same penetration as 60Lb. compound bow) other barrel can shoot airsoft or 1/4" BB or 3/8" BB or pistol crossbow bolts.
The chamber size is overkill a little but it's small volume anyway.
Airsofts cool in some ways and the store bought replicas are "neat", But the caliber thing is a matter of opinion IMO.
BTW I was upset when I read yesterday that MrC may be leaving for military/moving soon, Then I posted some goofy reply here.
