yep,tgforce is right, those are fatty's of palmer,so ,a good friend have an short CP reg on his sterling,it's small,less expensive than palmer and working great.Dr M, what make is the short inline reg fitted on the two Sterling's
I could do with a stubby unit like that on a couple of my 1/2 finished builds
£200 worth of stab regs in that last picture Dr M - take it you're a fan, does it make much difference on the Phantom? - oh and which undercocking kit is that?
