Sako Forester Mannlicher Carbine 7mm-08 DM Prototype

Sako Forester Mannlicher Carbine 7mm-08 DM Prototype. Gun comes with 2 types of magazines - the internal mag with drop floorplate (as shown) and a detachable magazine with bottom metal shown. My understanding is that Sako shipped 6 rifles this way, (3) in .308 and (3) in 7mm-08. Gun is in 99% condition and comes with the optional magazine and bottom metal, scope rings, manual and box. This is a Stoeger import.
