While waiting for some glue to set I thought I'd take some photos to show the difference between the centres of the aluminium oxide centres of the Fuji BSVOG rings I fit as standard and the Alconite centres of the BSVAG pattern which a customer has requested. The frames are identical but the Alconite centres are markedly slimmer. Naturally there's a price premium to pay for that!
This is the first time I've fitted BSVAGs. I still prefer the BMNAG frame for aesthetic reasons, and the practicality of the rolled frame, if I don't want to go to the expense of Silicone Carbides on my own rods. If you really must have 50mm butt rings then the choice is between BSVAGs or Kigans as the BSVOGs get really clunky at 50mm. There's not much in it in terms of price but the Fuji frames are much more nicely finished than those of the Kigans.
