If you have BH209 listed in the manual it just seems logical you should include the plug. It wouldn't take much to offer them with 1 plug of your choice but of course CVA pushed WhiteHots for some odd reason. It pretty obvious if you watch their Youtube videos. Knight offers them either way on most of their rifles. FPJ or NFPJ which is better for BH209.

Neither Rem or UF directly approves using BH209 and UF even says not to use it. Wakeman was the only one recommending BH209 in the RUM and he has since backed off....Care to guess why?
