Gunsmithing If only I had few more inches....

[PinesAndProjectiles]

I've got a Vudoo mounted in an MDT ACC chassis. The barrel length is 18 inches, so it only sticks out past the end of the chassis by 1.1"

Which creates a problem when trying to set up my Magnetospeed Sporter.

I've looked around and found mounts to attach a Magnetospeed to an ARCA rail, but they are expensive and I'm a cheap ass.

Does anyone know if I could attach a "barrel extension" to give me a few extra inches to work with?

I take it you do not run a .22 can?

Post a pic. I’m having a hard time picturing how you’re mounting your MS now.

 

[PinesAndProjectiles]

I can't currently attach my Magnetospeed because there isn't enough barrel.

So could I purchase a barrel extension to attach the Magnetospeed to?

I've got a TBAC on order, but it's going to be a while.

Is there a reason you can't come up with a mount to work with the rail

I'd need an ARCA clamp, and then have to build or buy something.

I'm thinking a 2.5" piece of steel threaded 1/2-28 on one end with a .500" hole through it would work just fine.

You could get a fake rimfire can as a stop gap

Just looking at it I’m not even sure the arca would work. I’d send that pic to MS and see what they say.

This would work perfect. Thanks @Trigger Monkey !

Sorry, does I have a Vudu in a mdt chassis and I can’t figure out how to mount my ms fall into the “ I’m a cheap ass” category ? Lol just messing with you

 

[buffalowinter]

I don't understand, you've got six inches of barrel there.

 

[Fig]

Even with the ARCA rail choked up as far as it will go I'm thinking there isn't enough room for the back/thick part of the bayonete to get close enough under the barrel. You can add the spacers to go further away if you're running a can, but there is a minimum distance on a bare barrel...

Even with the ARCA getting the bayonete in the right spot the chassis is in the way and I think you're going to be too far from the barrel to pick up the shot.

Well deserved, well deserved indeed.

Looks like a job for Labradar to me...

I mount my V2 right on my can and it fits perfectly for correct distance to bore to pick up the shots. 9” can on my .260.

How about a blast can? I use one on my 224v of all things (long story). It should give you enough space to mount the MS. I only paid $30 for one at my local LGS.

Well, there's that too lol

 

[Jrb572]

Take it out of the stock and set it up on a sand bag or something. You are just looking to get the MV correct? Or are you wanting to check accuracy at the same time?

Best option for a cheapass lol

 

[seanh]

You won't get an accurate reading if you take it out of the chassis. Recoil velocity has an impact on muzzle velocity.

don't be so logicaal

could mount it around both the chassis and barrel too i believe?

 

[Jrb572]

You can’t get any cheaper

 

[1moaoff]

Mount it over the top

 

[hlee]

Mount the MS on top of the barrel. There looks to be enough room between the barrel and the chassis that you would maintain free float, even with the nylon strap threaded through the gap...

 

[acudaowner]

you could always get cheaper the real question is would you really want to .

just to get a speed idk how much free float matters. there's a POI shift anyways

I do that on my AR.

 

[PinesAndProjectiles]

I received a fake Gemtech suppressor and installed it on the barrel. Now I find out that the Sporter doesn't really work on Rimfire rifles unless the barrel is relatively thin.

The Vudoo barrel is hung like a horse and the Sporter doesn't even work!

I should have just tried mounting the Sporter upside down first. I guess I'll try that next.

 

[Ledzep]

Remove all of the spacers. I mount my sporter bare plastic to my 1.5" cans and it picks up. I guess I've never done slow .22's but it picks up .300 blackout subs and .224 supers.

 

[PinesAndProjectiles]

Thanks Zep, I'll try that too.

 

[Powder_Burns]

Had a similar conundrum with my .308 gas gun. Ended up mounting a mlok pic rail on the side of the handguard and used the pic rail adapter from magnetospeed.

 

[powdahound76]

@MinnesotaMulisha - where you at?

Surely someone near has a V3 they could meet up and put on there for a few shots?

Im in Denver if ya wanna come shoot!

I'm in the Forest Lake area. I'm sure I could find someone, but that doesn't sound nearly as good as a trip to Denver!

 

[powdahound76]

Well, denver is just another lib cesspool.

But we have cool stuff nearby.

So the wall thickness of your fake can won’t allow A reading?

If you want I can turn it down for you. I’m just north of Cambridge..

 

[PinesAndProjectiles]

I don't think it's wall thickness. I think it's more of how far the sensor in the Magnetospeed is away from the center of the bore.

According to Magnetospeed's website, the Sporter is only designed to work with a maximum barrel diameter of .850" where as the diameter of the fake can is about an inch in diameter.

gotcha. Well if your interested I’d turn it down to a smaller diameter for you.

 

[PinesAndProjectiles]

I tried running the Magnetospeed upside down with similar results.

I even removed the rubber spacer and had the plastic housing in direct contact with the barrel to minimize the distance between the sensor and the barrel.

Anyone looking for a Sporter, I may have one listed in the PX shortly.

If you turn up the sensitivity the sporter can be 1/2 inch away from bore and still work great.

 

[PinesAndProjectiles]

Brain fart. I checked the sensitivity of the MS and it was set to Reg.

Changed to Level 1, no go.

Changed to level 2, and now we're making money!

Seven shots and the MS recorded all seven. That's a win for this week!

Thanks for all the help fellas! Greatly appreciated!
