Actually, Browning A bolt production spanned from 1985 to 1993 when it was replaced by the A bolt II. The Stainless Stalker variants began production in 1987 according to Browning. I bought a Stainless Stalker in 300 Win Mag in 1992. Then my 338 WM in 1993. The Blue Book of Gun values (see below) will show you this or you can just visit Browning's web site to see for yourself. Scroll down through the production dates to see. No custom or prototype or special run...just regular old production.
