I'm interested in the Browning B 78 in the classified, Octagon barrel, Are mounts still available? I can't find any

If the bases are the same as the ones used on the 1885s, I have a Burris pair.

MT DD FAN,

My B78 had Burris mounts that required a higher front/lower rear ring. I used med front/low rear rings. If yours are the same they should fit.

no idea if they are the same

Check Talley, the regular ones, not the LWs.

Mine has Browning bases. I'm pretty sure the bases for the 1885's fit. Only major difference between an 1885 and the B78 is the stock and trigger?
