Note to Big Boy Owners (H006 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 we 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 = BB0047222H006M = BB0015530MH006C = BB0021188C ALL H006G/H012/H012G/PG Big Boy Series guns are 2nd Generation. The BB-CSM measures out at 5 5/8" with 2 fixed slots.The BB-RSM measures out at approximately 4 5/8" with 2 fixed slots.The BB-RSMP measures out at approximately 4 5/8" with 11 adjustable slots.If you would prefer a solid ring and base set piece as opposed to a Weaver or Picatinny base for your 2nd Generation Big Boy, you'll want to take a look here. Note to Golden Boy Owners (H004 Series) H004 Series guns with a Brooklyn, NY rollmark on the barrel were not drilled and tapped for a scope mount. If your gun is NOT from Brooklyn, NY you can use the GB-CSM or GB-CSMP mounts for the H004 series guns. The drilled and tapped holes are located under the rear sight.

Note to Henry Classic, U.S. Survival Rifle and Henry Pump Owners (H001, H002, H003 Series) The receivers on the H001, H002, and H003 series rifles have a 3/8 inch dovetail running along the top of the receiver. You can use the HLPA001 Picatinny adaptor listed on this page to convert the 3/8 inch groove to 1 inch slots for if you wish to mount a red dot optic, or Weaver/Picatinny rings for a scope. Measures out at approximately 4 1/2" with 11 adjustable slots.If you are putting this rail on the H002 U.S. Survival rifle, they will have to be removed before disassembling back into the stock.
