If I had a piece of round stock steel....1/2" to 1" OD, something in there, and had it D/T'ed to accept the threads/bolt from a tripod shoe, that round stock could be fitted to a tripod shoe, and then the Magnetospeed mounted on the round stock. Then setup the tripod in the appropriate place to put the MS unit under the barrel. What I'm not sure of is if that would put the unit too far from the barrel? And how to make sure the barrel is correctly aligned to the MS unit for proper readings..... but has my wheels turning.
I think it would.
Alignment with bore and distance from bore axis is important.
If you're too far below the bore, you're gonna miss shots. If you move the barrel to the next target, even at a hundred yards and not realign the bayonet with the bore, you'll miss shots.
And of course, you don't want to shoot the bayonet. Those issues are the draw back to the free standing set up.
The good points: no change in POI and one can swap rifles to let a barrel cool and not have to reattach the device.
To me, the positives out weigh the negatives.
