Another great use that is possible is as a great replacement for the Knight's Armament KAC 30mm rings, which are out of production, but are needed for a Mk11 Mod1 build. With the exception of the quick release, the ARMS #22 have a very distinctive look that can take the place of the KAC rings as well.
For a SAM-R build, or a Mk12 Mod1 build, you will want the ARMS #22 high rings.
These Medium height rings are short, and may have issues mounting a scope and rear back-up sights. These shorter rings are made for the Mod 0, which would normally run a Leupold Mark 4 scope, and have pretty good clearance, but are lower to fit with the SWAN rail that fits on top of the receiver top rail, and thus the shorter height.
Note: These are 2018 production items, so they do contain the normal 90 degree stop, despite the pictures looking otherwise.
