 Note to Big Boy Owners (H006/H012 Series in .38/.357, .44m, .45lc, .41m, .327/.32)

Previous production or 1st gen Brass Big Boy guns 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 gen 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 Gen Brass Big Boys you can use either the BB-RSM (weaver-style) or BB-RSMP (picatinny-style) rails. Ring/base combo also available for 2nd gen, linked below. 2nd generation Brass Big Boys start with the following serial numbers:

H006 = BB0047222

H006M = BB0015530M

H006C = BB0021188C

ALL H012 Series guns are 2nd Generation.
