M3 barrel support I made for use with the Airmarksman zero moa backbone.

Thank you. It really helped with the 700mm flex. I first tried a 3d printed band. That did not marry the barrel as well as I had hoped. This concept appears to have moved the flex to the arca rail under the bottle.

This is a shot string using .218 33 grain Zan slugs. The new support has helped with the accuracy.

Very cool. Those backbone rails open a wide door for innovation and tweaking. I like that your design can pivot at the screws - will allow it to also work on the 30MOA rail. 
Thank you. That’s for sure, the gun is much less hold sensitive than pre backbone. The slip fit bushing that I made for the backbone through hole will allow for placement experimentation, assuming that the through holes are consistent. If not, it’s not a problem to make a new bushing.
