  • Magnetospeed Adapter

    MPA has come out with a Magnetospeed adapter but it doesn't work with suppressors so I decided to build my own. Adapter connects directly to chassis via front pic rail. Works great, no POI change. Easy on easy off.

    shooting 1K with a MSV3 attached are they ?
    Very nice setup.

    Take a look at Frank's interview with David Tubb where he actually shot the 2 Mile match/exhibition with his adapter. I personally find it very helpful during load development (OCW) and also when truing dope.

      ^^^With a sling support setup the weight of the chronograph is borne by the rail not the suppressor; it's the poor man's simple system. Some complain the MSV3 alters their POI. Some complain their suppressors alter their POI. Certainly the combination most likely does. I prefer to just get the MV data, remove the MSV3, zero the suppressed weapon at whatever range, establish your range dope either empirically or input into ballistic calculator for obtaining holds. So the necessity to have a free-floating chronograph seems to be an unnecessary luxury in my view.

        For me, there's not the need. But there is obviously a market.

          Agreed, there's no need but there is a want. I want to record every shot on my new build but still be able to see how it's behaving. And I know: labradar. But there's something about that I don't like and something about the v3 that I do. Maybe it's comfortability with what I know or recency bias. The adaptor just needs to accommodate my can and not make the combination more than a labradar.

            I want a Labradar ! with some of the idiosyncrasies resolved.

              For those that are not running suppressors or have a short barrel with / without a muzzle device my adapter is slightly different, however still 3-axis adjustable. In this setup I only use one mounting point to the rail adapter on the rifle pica tinny rail, doing so allows fine angular adjustment of the bore axis to the magnetic sensor deck axis; once exactly as desired, really snug it down and you are good to go. The fabrication is quite simple; I have used aluminum bar stock in 1/8" & 1/4" and Magpul polymer rails. Shown last are my adapters and riser options to get the task done. Shown mounted on a 6.8 SPC SBR. Haven't decided yet if I need to paint the brackets. You can source the rail clamps at holsterops.com. IMG_6422 copy.jpg

                Alright, got something put together for those of you that have a Magnetospeed Sporter. Really happy with how it turned out.

                Parts list:
                Quick Connect Picatinny Rail Adapter (knockoff of ADM style clamp) - $10 on ebay
                Aluminum L channel - $4 from Home Depot
                Screws, Nylon lock nuts, washers - $2.50 at the local hardware store
                Sling stud/swivel - already had on hand

                The QD clamp was a two piece clamp with screws already countersunk for the pic rail attachment. (see shortened ebay link here for the one I got - https://tinyurl.com/ya49qpu7 ). I removed the screws and drilled all the way through the picatinny rail to fit my longer replacement screws. The notched pic rail section rests against the edge of the L channel to help prevent twisting. I added enough washers to give me the proper standoff. At the other end I drilled a hole through the L channel to fit the screw from the sling stud, and located it so that the L channel rests against the side of the Magnetospeed to keep it from twisting. You can use the screw knob from the magnetospeed since it is the same thread pitch and also uses a sling stud swivel for the strap.

                Clips on/off in seconds, really light weight, and is very rigid due to the L channel material which prevents twisting and flex.

                Hope this is helpful to someone else. You should be able to make one in under 30 minutes with just a drill and a hacksaw to cut the L channel to length.

                    I've been thinking of one of these as well. As the rifle flexes under recoil, what happens to the adapter? How does it flex? Are the readings still just as accurate? I would imagine that when the MS is attached directly to the rifle, the barrel and the MS move as one unit. When the MS is attached with an adapter, who's to say that they don't move differently every time , or the angle of deflection is greater because the mounting point is a foot or so away from the bayonet?

                      Not 100% sure on the flex issue, but I can say that the whole assembly is quite rigid, even more so than I was expecting when I thought it up. The L channel really helps with that. Also, there's not much recoil since I'm shooting Dasher, lol. Should have it out for a range test this weekend to see how it does.

                          Have a sporter and looking to do the same thing. Cut the mounting portion down to give it more depth like the V3 to account for larger muzzle brakes. Just have to hit up lowes to see what I come up with.

                            My solution for my V3. All parts bought at Home Depot (except pic rail mount). Height adjustments can be made with the normal V3 spacers or smaller adjustments can be made by adding or removing washers. Small length adjustments are made by loosening the set screws and sliding the rod that the Magnetto is attached to in or out and I made a second longer rod for suppressor use.

                              Ok, after much thought about this subject I jumped in and made one for my Fat Rat. My design is made out of POS AR handguard I had laying around. And a AR15 rail adapter for a scope mount. This adapter is easy to install and remove in just seconds. The only mod was to shorten the handguard with a bandsaw. Nothing special is needed to make one, for longer barrels just get a longer handguard. Mine is on a 20" barrel with a 15" handguard.

                                Here is mine I got to use on my grendel and savage with xlr element stock. Mainly just in prototype stage so may clean it up more.

                                  You guys inspired me. I had to make one that would work with all my AXMC barrels. I made it adjustable for 26" to 30" barrels with my can on. I had an extra acog mount laying around that I used for the mount to the gun. I used one of my AI rail sections for the other end. The rod is just 1/2" dia. aluminum.

                                    I believe there has been one for about a year or so now. I know of several others that have been tested and are currently still being perfected. One of which would work for barrels suppressed and unsuppressed SBR - 40+ in total barrel length. Like I said though, several companies have had these things in the works for a while.

                                      If you know of something available commercially that will attach to a standard stock to a bottom mounted rail (like for a bipod) I AM All EARS.

                                        I recently contacted MagnetoSpeed to inquire about free-floating adapters and show some prototype designs of my own. Here is what Mr. Hey responded. I inferred from his answer that they will be staying in their mfg. lane of developing chronos, not a variety of mounting solutions, leaving adapter development to 3rd parties.

                                        By the way, does anyone know how to disable the annoying automatic spell correcting feature. Almost every time I post I have to re-edit some nonsense word substitution that has occurred.

                                          Thanks for the info. Seems like most guys are making alternative mounting solutions for AR'S & chassis sytems and/or spigot mounts. I need something that will work with an A5 type of stock. May have my smith take a wack at it.

                                          As to your other thing, go into "settings" and turn off the "auto correct" and that will solve the problem.

                                            Here is my entrance into the field. Going to make another thread for this, but here's a few pics. Very adjustable and mounts on a standard rail.
