diy carbon barrel sleeve?

i have a stevens model 62 .22lr that i just picked up in a trade and i want to do some tinkering. the only problem is that i cannot find any aftermarket goodies for it. i wanted a .920 barrel for it but cannot find one so im thinking about improvising. do you guys think it would be possible for me to turn out some bushings out of aluminum(one for the breach end and one for muzzle end) and attach them to the barrel with a carbon fiber tube fitted between them. so i could basically have one with a center bore big enough to slide all the way down the barrel then have a .25" shoulder flush fit with the o.d. of the carbon and a inner spud the size of the i.d. of the carbon(same idea for front). then i could epoxy the spuds into the tube and slide it over the barrel. i could then use some soft tip set screws to hold it into place.

Re: diy carbon barrel sleeve?

Your thinkin' is a bit out of the box, but just a bit. This would be an interesting project.

There is a gunsmith in Rexburg ID who has been playing with an idea similar to yours but with a different object.

He's rigging an aluminum sleeve over the barrel in a manner that allows for tensioning the barrel to tune it to optimum accuracy.

So. . . it seems something like your idea may work if you're willing to go through the effort.

Re: diy carbon barrel sleeve?

Tension barreled guns have been shot quite a bit in 1K BR. They have had good but somewhat erratic performance. They need more match to match tuning than most other setups. If you consider that a steel barrel and either an AL or carbon tube will have quite a bit different thermal expansion coefficient. If there is not something to conduct the heat from the barrel to the outer tube the smaller dia barrel will just hotter and have less air flow to cool. There are some 22 barrels with solid AL tubes epoxied over them I believe from magnum research.

Re: diy carbon barrel sleeve?

It's not only the barrel expansion when fired it's the expansion difference at different ambient temps. If you tune/sight in at 85 deg and then go out at 30 deg the amount of tension on the barrel will be different with the first shot. If your talking slow fire 22 it might not matter either way but if that's true it might end up being more of cosmetic change than anything.

Re: diy carbon barrel sleeve?

cosmetic would be a plus but performance is what i would like. i am hoping that by cutting down and sleeving my sporter barrel i can stiffen it up some. plus its also nice having a gun that sticks out when your at the range. just seams like there are 50,000,000 custom 10/22's and "tacticle" shotguns around here. to me just slapping a barrel/stock combo onto a 10/22 doesnt make it a custom its just more out of the box stuff. and putting a pistol grip stock on your shotgun doesnt automatically make it a tacticle gun. then again i am the same way about the vehicles i build (built not bought) so i guess it would make sense i think of my guns the same way lol.
