MK Machining Gen III Magnetospeed Mount

We’ve made substantial improvements to our very popular Magnetospeed Mount for better performance with long barrels and suppressors. Beefier construction, larger hardware, and a 5/8” rod rather than 3/8” provide a sturdier experience, particularly with the bayonet set further from the mount.

Unique 3-piece clamp works with both Arca & Picatinny rails, needing just one slot for installation and 2” of rail space. Two-way adjustment via four stainless steel adjustment rods should provide adequate movement of the bayonet for nearly all rifles. There is NO CANT adjustment of the bayonet, meaning if you have an angled forend or a rail that is not parallel with your barrel, this mount will not work for your rifle.

Fully CNC machined 6061 aluminum and stainless-steel construction. Type III Hardcoat Anodization.

    By far, the best Magnetospeed mount on the market. Easy to adjust and get just right. Very solid. Keep up the great work guys.

    Tip: Go on Amazon and buy a 2.5mm and 4mm Klein Tools Hex with Journeyman T-Handle 6-Inch for easy adjustment.

    Bonjour de France 🇫🇷
    Matériel bien reçu. Il faut compter une quinzaine de jour.
    Très qualitatif. Je précise que l’attache de la baïonnette du magnetospeed est bien fournie.
    Pour les compatriotes, la taxe douanière est de 45 € 😉

    Not a complete setup. You’ll get this, put it together, and then realize that you have to come back on here and order an essential piece to attack the chrono to this whole setup.

    When you go to the range with this contraption make sure you bring your entire tool bag!

      Hi Jake,

      If you have a Magnetospeed V3 as mentioned, this is all you need! A standard allen key setup is also all you need in terms of tools, specifically two allen keys. Please reach out to us if you have any questions!

    This is the best add on you will ever do for Magnetospeed I only wish I would have done it earlier. Easy to install and high quality.

    strapping my Magneto Speed to my rifles was hit or mis for me. Many times I would have to retighten the strap after every shot. With this M&K Magneto Speed mount I can use it on any of my rifles or pistols as long as it has a picatinny rail mount. I even went as far as changing out my lever action forends so I could measure the velocity of my reloads on my 30-30 & 45-70 rifles! Thanks M&K for your most excellent work and engineering!
