Gunsmithing remington switch barrel.

Ive never put one together, It wouldnt be hard to do. For the average Joe to switch the barrel they would need to right equipment to do it and just double check it with a go/no go gauge. Would help if the recoil lug was pinned to stop it from moving.

All the upside of a 700 action footprint, with the DIY ease of Savage barrel swaps.

Yes, it should be very 'dependable' and you can safely change barrels with as little as a shop vise & notched hardwood blocks, a barrel nut wrench, a dead blow hammer, a go-gauge and a piece of scotch tape.
