Barrel Tuner, the quick and dirty version.

[Clobbersauras]

Thought I'd post a little sumpin' I had made for testing on my eagerly awaited Dlask DAR-22 threaded receiver.

I had it made using a Dlask Reworked Levang Comp as a base. I had some positive indications that the Levang comp worked to improve accuracy in my current DAR 22 so I decided to use it as a base to make a barrel tuner.

I'm still learning about barrel tuners, but generally those that use them swear by them. I had been thinking about this modification for a while so I just decided to do it. There are other devices that use a similar method to apply adjustable weight to the barrel, but AFAIK nobody has been dumb enough to use a Levang as a starting point.

I had a machine shop thread the outside of the Levang and then had two threaded collars made to screw onto it. The threads are very fine and provide a lot of range of adjustment. The unit is adjustable throughout the whole length of the device and you simply have to tighten the two collars together to get it snug enough not to move easily. To help with this I had two holes drilled in each collar so I could get a small allen key in there. I'll have to use a magic market to mark the positions during testing, but no big deal.

So I'm hoping that this device will give me the best of both worlds; the bullet stabilizing effect of the Levang, combined with the barrel dampening effect of the added weight of the collars. The new DAR-22 threaded receiver should be a real tack driver on it's own, and I'm not sure that I have the skill to realize the small benefits this muzzle device will provide, but I look forward to the fun of finding out!

Yes I know it looks like hell, but I won't care if it helps shrink my groups.

Looks good Clobb!
Keep us informed of how it works!

 

[Clobbersauras]

Thanks, will do. It's going to take a while to properly test it. I have to break in the DAR and find ammo it likes, then create a base line of it's performance before I can even get into testing with this device. It's all fun stuff though, but I'm looking at months worth of testing, and it may not improve anything....

Should do something, thanks for keeping us posted!
Oh, what did the machine work cost you?

 

[Clobbersauras]

It was a local shop, they charge $70 an hour I think. It was 1.5 hours of work. Had it back to me in two days! I was impressed!

 

[Wham-O]

Lector charged you $70 and hour!!!

Looks like he's buying the beer this weekend!

 

[Clobbersauras]

^^^LMAO!!!

This wasn't done by the Doctor. I don't think he has the time for a project this lame.

 

[Wham-O]

Good to hear he's busy.
Maybe that'll keep him out of trouble for a week or two.

Thanks Clobbersauras, looks like you could apply that principle to any firearm with a muzzlebrake.

 

[Clobbersauras]

Yes, any barrel that is threaded 1/2x28 would work. It would be hard to make this idea work for most brakes and flash hiders though , you could make it work for things like the Troy Claymore, bloop tubes and other devices that force blast forward.

Not all of those devices are created equal though. The Levang is special in that the internal structure works to divert gas away from the bullet after it leaves the muzzle. For that reason, in theory it may help to stabilize the bullet and provide better accuracy. That's why I picked it for this project. I certainly got some positive results from using the Levang, but it's very hard to test this in outdoor conditions with my skill level.

Neat project and great contribution to the rimfire section. Please let us know the accuracy results. Even if it doesn't work, it's a cool project. Good job.

 

[Clobbersauras]

Thanks, I'll update the thread when I get some results.

Neat
