Note to Big Boy Owners (H006/H012 Series)

Previous production from pre-2011 (or 1st Generation) Brass Big Boy rifles were drilled and tapped on the barrel under the rear sight, they were NOT drilled/tapped on the receiver. You will need to use BB-CSM for 1st Generation H006 Brass Big Boy series.

In 2011 Henry began shipping 2nd Generation Brass Big Boy rifles which feature receivers that are drilled and tapped for the scope mount. For 2nd Generation Brass Big Boys you can use either the BB-RSM (Weaver-style) or BB-RSMP (Picatinny-style) rails. 2nd Generation Brass Big Boys start with the following serial numbers:

• H006 = BB0047222
• H006M = BB0015530M
• H006C = BB0021188C

ALL H012 Steel Big Boy Series guns are 2nd Generation.

The BB-RSMP measures out at approximately 4 5/8" with 11 adjustable slots.
