Pre-81 Browning BLR scope base

[diegocn]

I was installing a new scope on my pre-81 BLR in 308 today, one of the screw stripped the screw hole in the scope ring. Now I need new scope base.

All the scope base I see for BLR does not specify whether it's for pre-81 or BLR 81. Does anyone know if the base are the same before and after 81?

I took some measurements on mine. There are 2 groups of 2 screw holes on top of the receiver. Hole measures 0.121" diameter, and are 0.618" apart within the group. Can someone with a BLR 81 see if this is what you have?

Make of rings/bases would help...……...me thinks.

Link with charts.

Thanks for the chart. Weaver lists 2 BLR models, BLR and BLR flat top receiver (older models). The top on mine doesn't look to be flat top, as the scope ring base is not flat.

I cannot tell what make the ring is. It's a see through type ring. Only stamping on it is WIDEVIEW on one of the rings.
