Just FYI the spigot I posted above on my AT has absolutely zero play whatsoeverElite iron is closer to barrel axis. And a spigot without a tensioner is gonna have play. Fwiw
Complete honesty I have absolutely no idea exactly how it mounts. Previous owner had on the gun when I purchased. But it’s rock solid. I use it all the time with my TBAC or Atlas. Then use the RRS Arca forend attachment for my tripod
