I was fortunate to source an OEM Win M-70 Safari Express rear sight assembly which will arrive tomorrow. I plan to install it on my Win M-70 Classic 460 G&A as the primary sighting system for my Zim trip. Do you know the sight radius - rear surface of front sight to rear sight blade - on a Win M-70 Safari Express 24” barrel? I’d like to duplicate the sight radius.
More useful techniciana: A .416 RemMag M70 Classic Safari Express (CT-made) walnut and matte black: Nominal 24" barrel is actually 23-3/4". Muzzle to front bead = 1.25" Breech face to rear sight notch = 4-5/8" (single standing fixed leaf, with insert adjustable with tiny screws on leaf) Sight radius = 17-7/8" = 17.875"
A .375 H&H M70 Classic Stainless (CT-made): Nominal 24" barrel is actually 23-3/4". Muzzle to front bead = 1.25" Breech face to rear sight notch = 4-1/4" (fold-down single leaf, adjustable with tiny screws on leaf insert) Sight radius = 18"
A .458 WinMag M70 Super Grade (FN/SC-made): Nominal 24" barrel is actually 23-3/4". Muzzle to front bead = 1.25" Breech face to rear sight notch = 5-9/16" (2-leaf pivoting on base, one up and one down, drift for windage, solid leaves filed for elevation, or change front bead) Sight radius = 16-15/16 = 16.9375"
Answer: Based on my sample M70s, it varies some, maybe depending on type of rear sight, all front sights same. 17" to 18" would be a good ballpark for sight radius for a "24-inch" barrel.
