I'm posting this to hopefully save at least one other person the time and money I spent getting the correct front sight height sorted out.
If you want to install the Browning Scout mount on a BLR *and* want a backup iron sight capability, here are the SKU's you'll need for one of the better iron sight systems plus a forward mounted optic. A taller front sight is needed to to work with the taller rear, and it also permits an unobscured
sight line between the rear and the front *over* the Scout rail.
All my testing was done with a 2013 production stainless takedown BLR chambered in .308 Win.

I would presume that the barrel exterior is similar dimensions for the .223 Rem and the other .308 parent cartridge chambering variants (.243, 7mm08), which would determine the required
sight height.
1 - Browning Scout mount - short action - #12327 (.308 or .223)
1 - Set Leupold QRW "low" rings matte - #49853
1 - Leupold FX-II Scout 2.5x28mm Duplex matte - #58810
Brownells:
1 - 962-564-380WB - Williams Rifle Fire Sight red 450N
1 - 962-027-250WB - Williams .250 Riser Block
1 - 962-100-750WB - Williams WGRS BAR (rear)
1 - 962-000-082WB - Williams 1/4" WGOS Slide/Ghost Ring
1 - 962-050-000WB - Williams front sight pusher (optional tool).
Configuration update:
Remove Browning rear barrel-mounted iron sight assembly
Install Browning Scout mount rail on barrel (I blue Loctite'd the screws)
Install Williams WGRS rear sight at the back of the receiver close to the hammer.
Replace included Williams rear peep insert with WGOS Slide/Ghost Ring
Remove Browning Williams Fire Sight (Red) factory .410 front sight.
(This is where the Sight Pusher is handy)
Install front .250 riser block (I blue Loctite'd the set screw)
Install front .450 sight (I blue Loctite'd the set screw)
(Sight pusher again)
n.b. total front sight height now .700 above dovetail slot.

I used a rear butt stock pack along with the .500 plus .250 foam spacers from Beartooth comb raising kit to ensure better comb height for the taller irons and optic for fast target acquisition. The stock pack can be used for spare ammunition storage and handy tools too.
Secured the foam spacers with tape, and covered them with the stock pack.
Eagle or Tac-Ops stock pack will do the trick.

Test on range for 50 meter zero for irons and optic, adjust rear windage and elevation for a zero.
Optic have to be removed to access the iron sights. That's fast with the QRW mounts.
