Description
The Steiner P Series MSR Mount is built for shooters running AR-platform rifles who need a repeatable, no-compromise mounting solution for 30mm scopes. Its one-piece construction eliminates the alignment variables that come with two-ring setups, so the scope tube seats consistently every time the mount goes back on the rail. That matters most when the mount comes off for transport or maintenance and the shooter needs to return to zero without a trip back to the range.
The Picatinny interface locks into standard 1913 rail cuts, giving the mount a precise mechanical reference point rather than relying on friction alone. On an AR or similar gas-operated platform, where recoil impulse is short and sharp, that positive indexing helps the mount resist the repetitive rearward shock that can shift a less securely anchored optic over time. The 35mm mount height is sized to work with the AR’s elevated sight line, putting the shooter’s eye in a natural, comfortable position behind the scope without requiring an unusually high cheek weld on a standard stock.
Steiner machines the P Series from aluminum, keeping overall weight in check on a platform where muzzle-heavy builds are a common complaint. The black finish is consistent with the rest of the P Series line. For a shooter who already runs a quality 30mm optic and wants a dedicated mount that fits the ergonomics of the MSR without adding unnecessary bulk, the P Series mount addresses that need directly.
