Curious to see if anyone is using the new MPA magnetospeed adaptor?
I see that they make one for suppressed and one for non-suppressed, and when you order they ask barrel length.
Am wondering if you use a brake if you need to add that to your barrel length.
They are hard to get ahold of so I thought I'd check with you guys first to see if anyone is using yet.
 
Thanks Eric.
I think I am going to order one - I know they want you to specify barrel length, but not sure if that takes into account the length of a brake.
They look like they have a fair amount of adjust, but hard to tell from their pics.
Might just email Al - he's good about responding but I know they are swamped.
 
I have to say, I liked it for when my MPA chassis arrives. The rod the bayonet attaches to is drilled at four different spots so you could affix the bayo in two different locations: one closer to the chassis, another about an inch further out. Since it comes with the MPA dovetail base, you should be able to adjust the length to cover most barrel lengths just by sliding the plate forward or back on the chassis' rails.
 
I have the adapter attached to the spigot mount and the Magnetospeed Sporter. The length is good with with a 26 inch barrel plus brake. The setup probably wouldn't be long enough without the spigot mount on my rifle and the Sporter.

For those interested I notched (down) a spot for the rod to sit in into the Sporter frame / body. After changing to the medium sensitivity setting it records every round.
