I recently bought one of these for a project, and came to find out it is permanently set up for 5.56 ammo.

Not a caliber for me, so off it goes. If anyone is interested, please PM me and we can deal.

Fits on a regular picrail. https://www.steiner-optics.com/products/m332

I'm not sure this is under the right heading, so if it needs moving please do so.

Thanks, Sub Rosa
