I'm in the process, if I ever get it done, of building a Whelen. I bought an old Springfield Armory '03 receiver{$125} and had it barreled to .35 Whelen($200) had Remengton sights in junk box in the shop but($30 to drill holes in barrel), added a plastic RamLine stock(100), a low safety($20) and a A4 low scope mount bolt($50). Barrel chanel of stock needs inletting to free float, yet. Starting to come together but, I've not shot it yet. My question now, is to have the receiver drilled for a scope mount or leave it for iron sights, '03 receivers aren't getting any cheaper.
