IIRC, that's the old style Smith(?) mount that had a front and rear pad, instead of a full rail.
Just use a cantilever Aimpoint mount off the front of a Smith/ARMS/etc mount.
IMHO, an Ultimak or other scout mount would be the way I'd go.
Steve,
If you use the cantilever mount, the reddot starts become increasing high on the rifle....
I agree...go with a scout mount of some manner....will save you pain.
The scope mount your thinking of is the old arms 18....uber rare ....
funny. Never noticed till now, the image on bottom is reversed. OP Rod is on LHS. Must be the new Stag Arms M14 leftie model.
The UltiMAK M8 mount fits only standard, GI spec barrels. In the current Springfield line-up, the compatible models are; M1A Standard, M1A Scout Squad, SOCOM 16, and SOCOM II. The "Loaded Standard" and all of their "Match" and "Tactical" models have heavier-than-standard barrels, which will not allow M8 mount installation.
Been reading on the Ultimak website & it won't sit on my medium weight barrel..
