Update on previous post:
Change of plans: I am NOT putting the 54.30 action into this AS stock.
I will be putting in an Anschutz 54.18 action with a Lilja barrel.
You see, I have a 54.18 BR50 repeater that I got from the old Anschutz NA Custom Shop in Las Vegas, Nevada.
The 54.30 and 54.18 actions are very similar in dimensions except for the magazine assembly in the 54.18 (actually a 54 action in the 1800 series). AS Rifle & Stock has already inletted the stock with a 54/1913 action (1900 series) which is identical, but for the magazine assembly.
I'm going to pull the action & barrel from the BR U2 stock and plop it into the AS stock.
I'm going to send this stock and action to Las Vegas, where a very very experienced gunsmith/friend will open up the bottom of the stock for the magazine assembly.
