Nobody makes bases to fit as many guns as Weaver. Yet each base is machined to tight tolerances for a custom fit. They're designed to fight the effects of recoil with a square cut notch that precisely mates to the sturdy cross bolt in every Weaver Detachable Ring. Custom hardened fastening screws come with every Weaver base.

Fits:
Browning 1885 High Wall, rear; gunsmithing required
Enfield receiver cut down, front or rear
H&R 317 and 322, rear
Mossberg 810 RM7, front
Remington 30 and 720, front or rear
Savage 29, rear
Savage 40 and 45, front or rear
Western Field 730, front
White W series, front

Note:
On the Browning 1885 High Wall with octagon barrel shimming is probably required for perfect scope alignment. Front base may require modification for correct fit.
