A magazine? Same mag for a .243, .308 and .358. Gunparts wants $55.40 for one when they have 'em. One sold on Gunbroker, in October, that had a bid of $181.

You are correct I am looking for a 3 round box magazine for a 358 c BLR pre 81.
I tried the sites the others suggested Gunsamerica and Midwestgunworks no luck on either. Any suggestions?
