MK machining keeps promising their gen III version soon.
Those that have the Wiser Precision mount, or the older MK mount
which do you like?
 
me and three buddies all have the wiser. set it and forget it for the most part.

i've never used the MK so i can't say which one is better.

but the wiser does it's job and does it well. don't think you can go wrong either way
 
I have the Wiser precision and it gets the job done, however I think it could be redesigned and more user friendly. Switching from a parallel stock or chassis to a stock/chassis that tapers at foreend is kind of cumbersome. I have been looking at the M/k machining just have not pulled trigger due to the pre-order.
 
MK Machine Gen3 is working great for me. It’s easy to setup and rock solid.

Here it is attached to the spigot mount on my TRG with 24” barrel and suppressor.

I'm a bit confused. How does your MK mount "shift" your POI? The original MagnetoSpeed strapped onto your barrel, suppressor, whatever? Yeah, it understandably shifted POI. How does a mount that is affixed to a picatinny rail or dovetail influence the barrel?

You have something right next the bore millimeters away from the bullet exiting the barrel. There is the possibility of disturbing the bullet flight.

I’ve use the old MK mount and the newest MK Mount. As well as a few others.

I would have a poi shift about .2 away from the bayonet no matter where it was. Put it low left and the poi would move high right, etc etc.

This was consistent across several rifles and barrels. Not everyone reports a poi shift and I’m glad you haven’t experienced it. However, that doesn’t mean it doesn’t happen.

So, to answer your question, it doesn’t affect the barrel harmonics, but it can affect the bullet leaving the muzzle.

I wouldn't of thought it would be detectable at a 100yds, but if you're seeing it, you're seeing it.
Can't say I've had those issues with the MPA set-up.
Must be consistent though (deflection wise), as wasn't David Tubb using a MS during the King of Two Miles event?
 
Roughly how far below the bore do you go and what sensitivity do you set it to? I have a homemade mount but haven’t really used it since I don’t know how accurate it is with the sensitivity turned up. Do you see any inconsistency in the readings with the sensitivity higher?

I was one of them guys received mkm g3 and i can honestly say...it shifts POI egen setting sensitivity higher and making bayonet bit away from muzzle bore..

That’s exactly what’s happening in some cases.

And, like I said, if that's what you think is happening, more power to ya
 
Canezach,

Might I ask, what do you think is happening to the dozens of shooters who are getting repeatable POI shifts with these Magnetospeed mounts?

Not at all trying to be offensive, but if you suspect something else, do share.
 
Also, if you guys plan to only use the Magnetospeed on one rifle, it’s fairly simple to make a home made mount.

- 3/8” (.375”) aluminum/steel rod (2’)
-4-40 socket head screws
-some sort of Picatinny or ARCA clamp capable of having a 3/8” hole drilled and a set screw

Drill the rod out to have 4-40 screws pad through at 1.350” (I think, may be off on the spacing) intervals or a division of that interval to adjust the spacing of the Magnetospeed fore & aft.

4-40 screws direct thread into the top of the magnetospeed v portion

Run it back to your Picatinny/Arca clamp with 3/8” and set screw it in.

Height can be adjusted with the included spacers and longer 4-40 screws.
 
I’m still using the MK gen2. It’s a little bit of a pain to get set to different rifles but it doesn’t take that long. As far as POI shift, I have experienced around .2 mil opposite of where I have the bayonet mounted, however I really don’t care as I really only use it after load development is done just to confirm MV and make sure my ES and SD aren’t too far out of line. I also have a second bayonet that i use to strap on my hunting rifles that are in a traditional stock that have no pic rail for the MK Mount.
All in all the magneto speed forms well for me and don’t plan to use swap to the Lab radar till more of it’s issues are worked out or something better comes along.

So, it's been about a year and I didn't see this post back then lol. I was thinking about this "issue" lately, but I honestly have no idea. If someone says there's an issue because of the MagnetoSpeed bayonet, then why isn't every single MagnetoSpeed shooter complaining? I've used the MagnetoSpeed for about five years now and the only time I've experienced any shift is when I was strapping the bayonet onto my suppressor. Well, a shift would be expected in that instance.
 
I get no shift with the wiser mount.
I also max out the sensitivity and hold thebayonet away from the bullets Path a bit extra

Good to know. I bought a Wiser a couple months ago but have not used it yet. I've only used the Magnetospeed on the AR-10 so far and did a comparison with the LabRadar that had more variation than expected. I got the Magnetospeed mostly because my son wants to get into ELR comps and I think it's good to be able to get MV live when learning to ELR comp.

Check your measurement Distance settings on the Labradar.
 
I actually was using my Magnetospeed today and was able to confirm some things that I felt I already knew...

FWIW: The set-up was on a Proof Competition Contour (super heavy contour), strapped to the barrel.

1.) Shift was present when the sensor was very close to the flight path of the bullet upon exit of the muzzle. Shift would go away when I added another spacer and moved the sensor further away from the flight path.

2.) Shift occurs opposite the position of the mount (the sensor “pushes” the bullet away).
Mounted at 3 o’clock, the group would print at 9 o’clock, mounted at 6 o’clock, the group would print at 12 o’clock.

3.) The weight of the sensor does effect harmonics. You may not see it on a heavy barrel in the middle of a wide node, but a thinner barrel not in a node; it does effect.
