Right - I’d venture if an MD is generous enough to let the stock change, they won’t care about bottom metal change either.
Went through that a bit myself, the NRL22 has a “Base class” where guys can shoot any model with an MSRP below $350. Problem is, I don’t care - for any reason - to shoot a factory Tupperware stock, so I strapped on a Boyd’s on one of my Savage Mark II’s. Boom, puts me in Open class. I’d rather play and lose than not get to play, and I don’t care for any of the factory rifles on the Base list, so I’m shooting open. Would love to have a Voodoo, but for the money, I’d rather build another specialty pistol or CF rifle, so my Savage does good enough (mag’s suck).
