Last month I published a review of the MasterPiece Arms MagnetoSpeed V3 mount and coincidentally on that very day I stumbled across the Wiser Precision MagnetoSpeed mount through social media. The Wiser Precision mount appeared quite intriguing. So intriguing that I placed a pre-order a few minutes after reading about the mount on the Wiser Precision website.
So what exactly prompted me to place an order for the Wiser Precision MagnetoSpeed V3 mount?
The first feature is that the Wiser Precision mount uses a ~1″ diameter carbon fiber tube as the foundation of the mount. The tube has a clamp at one end, which comes configured for Picatinny as standard, or with Arca-Swiss as an additional option. I ordered the Picatinny and Arca-Swiss option.
The second feature is the fact that the Wiser Precision mount allows for vertical adjustment of the bayonet with its bayonet bracket.
As you can see, it relies on the MagnetoSpeed strap mechanism. More on this later.
The third feature that made the Wiser Precision MagnetoSpeed mount very appealing is the display bracket that mounts the MagnetoSpeed display onto the Wiser Precision carbon fiber tube.
The Wiser Precision MagnetoSpeed mount has five fundamental pieces. The (1) clamp comes pre-attached to the (2) carbon fiber tube. These two items are then combined with the (3) display bracket, the (4) bayonet bracket, and the (5) bayonet bracket slider.
Assembly of the Wiser Precision MagnetoSpeed mount is not straight-forward when it comes to the bayonet bracket. Wiser Precision does not provide any documentation. There is only a paper included in the box with the URL to an installation video.
Unfortunately, the video was shot with poor lighting, but I was able to follow along with a lot of video pausing.
After I assembled the Wiser Precision MagnetoSpeed mount with the MagnetoSpeed, I immediately took note of the bayonet bracket slider assembly.
The slider moved back and forth and rotated easily, to the point where I did not think it would hold under recoil. I wondered why they would not have put a clamp on it, or even a set screw, to lock it into place after it was set.
Then the day after the Wiser Precision MagnetoSpeed arrived to me via USPS, Wiser Precision sent an email indicating they already received early feedback on the slider not remaining in position under recoil, and that they were sending out a new slider piece to all initial purchasers free of charge. A week and a half later or so, the new bayonet bracket slider was received.
The updated slider has a clamp built into it, and Wiser Precision reduced the internal diameter of the slider to be tighter.
In the interest of testing, I decided to keep the original slider on the mount for the first round of live-fire, but brought the upgraded clamp version with me to the range.
Note: I actually did not try to put the updated slider onto the tube until I was out on the range, but more on that later.
I was finally able to get to the range after having the Wiser Precision mount in hand for more than two weeks.
I put approximately 25 rounds through the gun before I took a break, and then I noticed the bayonet bracket assembly rotated clock-wise (when looking down the barrel from behind the rifle) about 5 degrees. Fortunately, I did not strike the MagnetoSpeed bayonet, most likely because I had adequate clearance on the bore line when I initially set the vertical adjustment of the bayonet bracket.
After this, I decided to swap out the original slider with the updated slider.
Wiser Precision indicated they reduced the internal diameter of the slider to account for the smoother surface of the final production carbon fiber tubes. This is true, but it looks like they overcompensated in the diameter reduction because the slider is very difficult to get onto the tube and move fore and aft, even after completely removing the clamp shaft.
Further evidence of the slider’s internal diameter being too small is the fact that the clamp shaft does not thread in straight after the slider is on the tube.
The likelihood of the bracket slider assembly moving on recoil is greatly reduced, especially with the clamp, but moving the slider is now quite difficult. If anything, Wiser Precision should have added the clamp, but maintained the same internal diameter of the slider.
I am thinking about going back to the original slider revision, and then using a hose clamp over it. That way, I can still have an easy time adjusting the bayonet slider assembly when the whole mount is moved between rifles, yet I can still lock it into place.
One other complaint I have about the Wiser Precision MagnetoSpeed mount is the display bracket. The MagnetoSpeed display simply locks in by friction and tabs/ledges molded into the inside of the bracket. You push the display into place and pull it out to remove. The only thing securing the display into the bracket such that it does not pop out is the MagnetoSpeed cable.
The plug actually fits through a hole in the bracket and will not allow the display to fall out.
But when actually using the MagnetoSpeed display in the display bracket, you need to support the back of the display with the hand, otherwise you will push the display back. This is mildly annoying when using the MagnetoSpeed display while in the Wiser Precision mount.
With those complaints aside, I do actually like the Wiser Precision MagnetoSpeed mount more than the MasterPiece Arms mount.
While the MasterPiece Arms MagnetoSpeed mount ditches the bayonet strap, the Wiser Precision MagnetoSpeed mount makes full use of it.
The design of the Wiser Precision bayonet mount bracket enables the vertical adjustment for the bayonet, and makes the Wiser mount more functional and interchangeable between rifles with minimal effort, assuming those rifles have Picatinny or Arca-Swiss compatible rails.
During my testing of the Wiser Precision MagnetoSpeed V3 mount, I used my Mausingfield in 6mm Creedmoor which sits in a MasterPiece Arms BA Competition chassis. While it does have the Arca-Swiss dovetail machined into the forend, I attached the Wiser Precision mount to the spigot mount.
My bipod is mounted on the forend via the Arca-Swiss dovetail, and if I were to place the Wiser Precision mount on the forend (as opposed to the spigot mount), that means the bipod has to be placed further back on the forend.
While this is fine, this makes the rifle platform less stable (or less controlled) because of the decreased leverage on the bipod. Ideally, a bipod should be further down the rifle for more control.
The entire Wiser Precision mount combined with the MagnetoSpeed V3 feels fairy sturdy, unlike the MasterPiece Arms MagnetoSpeed mount which does feel less rigid due to the very thin diameter shaft for the bayonet mount that it uses.
The carbon fiber tube gives the whole system a rigid, yet lightweight structure.
The view behind the gun while using the Wiser Precision MagnetoSpeed mount is enhanced thanks to the integrated MagnetoSpeed V3 display mount.
I feel that the display mount will be most useful while in the prone position due to the readily visible display position.
The Wiser Precision MagnetoSpeed mount comes in two different flavors: one for the Sporter and one for the V3 model. Both are priced at $100 and support Picatinny. Adding Arca-Swiss mount capabilities to either is an extra $35.
At $135 for a MagnetoSpeed V3 Arca-Swiss mount, the Wiser Precision unit comes in $20 cheaper than the MasterPiece Arms MagnetoSpeed mount (and required hardware).
If you are looking for a way to stock or chassis mount a MagnetoSpeed chronograph, where the rifles support Picatinny or Arca-Swiss, I highly recommend giving the Wiser Precision MagnetoSpeed mount a consideration. Even with the complaints I have about the system, I feel that these minor deficiencies or annoyances can be overcome by the user.
