The Picatinny rail has a similar profile to the Weaver, but the recoil groove width of the Picatinny rail is 0.206 in (5.23 mm) versus 0.180 in (4.57 mm) of the Weaver rail/mount, and by contrast with the Weaver, the spacing of the Picatinny recoil groove centers is consistent, at 0.394 in (10.01 mm).

The C7A1 (Diemaco C7FT) replaces the iron sight/carrying handle assembly used on the C7 with a modified Weaver rail for mounting optics. Canadian development of rails preceded U.S. standardization of the MIL-STD-1913 "Picatinny rail", so the "Canadian Rail" or "Diemaco Rail" differs slightly. There are 14 slots instead of 13, and each slot is ...
The only significant difference between the MIL-STD-1913 rail and the similar Weaver rail are the size and shapes of the slots. Whereas the earlier Weaver rail is modified from a low, wide dovetail rail and has rounded slots, the 1913 rail has a more pronounced angular section and square-bottomed slots. This means that an accessory designed for ...
Colloquially, the term dovetail rail usually refer to any straight mounting bracket with an inverted trapezoid cross-section (though the hexagonal-profiled Weaver rail and Picatinny rail are also derivative dovetail designs) running parallel to the bore for mounting a scope or diopter sight to a rifle. These are sometimes also called "tip-off ...
Among scopes for rail mounts, the 22.5-degree V-shaped Zeiss rail is the most prevalent standard. It was introduced in 1990. It was introduced in 1990. After the patent expired in 2008, compatible scopes have been offered from manufacturers such as Blaser , [ 1 ] Leica , Minox , Meopta , Nikon , [ 2 ] Noblex (formerly Docter [ 3 ] ), Schmidt ...
Replacement of existing weaver rails with a MIL-STD-1913 rail capable of accommodating both a day optic and in-line forward mounted, AN/PVS-26 (NSN 5855-01-538-8121) image intensified (I2) night vision device. Reconfiguring the stock with a stock that incorporates a detachable box magazine, adjustable comb and length of pull.
The sighting system uses the multipurpose Weaver rail mount rather than the Picatinny rail for affixing sighting systems which can be purchased separately. This same scope mounting system is used on the HK21E , HK23E , and G41 (discontinued) series.
The Redfield scope mount removed the rear peep sight that was standard on the M1903A3. The scope used on the M1903A4 was a Weaver Model 330 or 330C, which was a 2.75x telescopic sight. The receivers were tested by Remington Arms and those that were deemed best, meaning those closest to design specifications were selected to become M1903A4s.
