The SM-22 is a lightweight aluminum side scope mount that works with Arsenal Milled SBR's, all SAM7K pistols, the SAM7SFK and AR-M4SF as well as any model Arsenal with the rear peep sight centered on the dust cover. This model will also work on VEPR folding stock rifles that have interference issues with standard SM-13 scope mounts. These have 2.9 inches of Picatinny rail per section, for a total of 5.8 inches of usable rail space. These are a low profile, one-piece, quick-release design with 7 picatinny slots forward of the rear sight and 7 picatinny slots behind the rear sight and are manufactured by Arsenal, Inc. USA.
The SM-22 utilizes a completely new mounting system based on the time-proven steel adjustable locking mechanism w/adjustable tension found on the SM-13 models. This allows for instantaneous attachment without any compromise to accuracy, unlike other mounts that attach to or utilize notoriously unstable top covers that were never designed to hold zero. Your firearm must have a side scope mount rail to utilize the SM-22.Â
