I just got off the phone with Warne. I had called about my favorite scope base for all H&R and now Henry single shot rifles, the M681M. It has now been discontinued. I looked high and low, and finally found a single base for sale, and bought it.
The guy said they hardly sold at all. The new base to replace it is the M981M, however it is a downgrade. The M681M was a full rail of slots, you could put your scope where it needed to go, and fit both picatinny and weaver scope rings. The M981M is only 4 slots, two scope positions. If it doesn't work, you are SOL, same as the original weaver bases.
I'm hoping anyone who cares will email Warne and ask for the better product to be returned. Even if you don't care, just realize we are paying the same price for an inferior product. The contact link is found below.
