Clean design. good support and ideal hammer/rear sight clearance - Henry Repeating Arms Co Weaver-Style Receiver Scope Mount For Henry Big Boy Rifles Gen2 BB-RSM

This base is drilled properly to make the most of the Henry's three hole base pattern; two aft, one forward. Other base/ring manufacturers suggest an 1894 Marlin piece as a substitute, but a two piece is not properly anchored up front and the patterns is off by at least 0.030" at the front and they hang over the front or back of the receiver. The Henry base matches the Henry receiver top perfectly and a 36mm objective Leupold 8x clears with low rings.
