Here is a question. Assuming it is even recommendable or allowed (?)....
If I was to put a faux barrel over the current 2240 barrel what is the maximum additional length one could add before there is a concern with the pellet not clearing the outer "barrel"? Is there a concern that any movement of the gun immediately after the pellet leaves the real barrel could result in the pellet striking the inside of the fake barrel?

As long as you need! If the shroud is straight and fits well to the host barrel, you won't get any collisions of pellets on metal.

just be warned that if you put an end cap on the faux barrel (shroud)that is just a bit bigger then a pellet, it will be technically a suppressor as it will reduce the sound a surprising amount, though if left uncapped, it might actually make it louder, not that im trying to give legal advice as i couldnt care less what anyone does as it doesnt effect me in the slightest, just some food for thought, i would say no issue aslong as to legality if you dont put any type of end cap over the hollow tube

Yes I definitely don't want any kind of suppressor so I wasn't thinking of any end cap on the fake barrel. actually don't mind if it looks like a large bore deal and I don't mind louder really and I imagined it would get louder. I am just fiddling with the idea of making it look like some kind of hybrid western steam punk carbine affair. not intending to make the real barrel longer or suppress sound in any way. all cosmetic... fake gun outside - real gun inside.

and Rick thanks... the challenge then is alignment and maintaining it I guess. I not talking a yard or anything!!

Murray,
A Crosman C11 fake silencer is longer than the C11 barrel. Note that the I.D. of the "silencer" goes from 0.33" at barrel to 0.43" at exit. "Silencer" is 4.25" long.

Also Murray if you believe what Crosman posts as specs, C11 without "silencer" 480 fps, tactical (with silencer) 550 fps. Same gun ???

Harry I believe that pigs fly! :D

Maybe the faux silencer has nitro methane inside as an accelerant??

Ya....... it's been bugging me since I wrote it. I would have tested it already but I took the lights off my chrony. Tomorrow for sure, with and without "silencer". I see they say the same thing about the 1911 tactical. I can't see why fps would change. Soooo I'll see.

Fake "silencer" result on C11. 399 fps without it on the gun and 406 fps with it on, both with Umarex BB's. If there was a difference in sound, I didn't notice.. both loud. I wonder what Crosman used for BB's as not close to 480 or 550 fps.

A tube may affect accuracy. The shorter the barrel and smaller the ID of the tube the worse the muzzle blast will be in there. I've seen guns drastically affected by something near the muzzle, but then others not so much so it's hard to say. I'd try using something like a plastic tube or whatever to see if accuracy changes before I invested too much time/money in it. If it were me I'd buy a longer barrel to match, that should give you some free power and be quieter as well.

I would get a longer barrel to match the shroud length.

You can retain the same velocity by trimming down the hammer spring a bit, not to mention save more co2 used per shot. 8)
