Among scopes for rail mounts, the 22.5-degree V-shaped Zeiss rail is the most prevalent standard. 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 & Bender [4] and Steiner.

It is similar in concept to the earlier commercial Weaver rail mount used to mount telescopic sights, but is taller and has wider slots at regular intervals along the entire length. The MIL-STD-1913 locking slot width is 0.206 in (5.23 mm). The spacing of slot centres is 0.394 in (10.01 mm) and the slot depth is 0.118 in (3.00 mm). [8]
Weaver rail mount, early rail system used for scope mounts, still has some popularity in the civilian market; Picatinny rail (MIL-STD-1913 or STANAG 2324 rail (cancelled)), the improved and military standardized version of the Weaver mount developed by Picatinny Arsenal in New Jersey.

Early MRADs had a 30 MOA slope full length 21.75" standard 1913 Picatinny rail on top of the receiver/handguard. Current MRADs feature a 20 MOA slope rail. Current MRADs feature a 20 MOA slope rail. Shorter 2"-4" Picatinny rails sections may be user positioned at 3, 6, and 9 o'clock at several fore/aft positions along the handguard.
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).
