Steiner T-Series MSR 30mm High Mount - Matte Finish

The Steiner T-Series MSR 30mm High Mount in matte finish is a single-piece cantilever scope mount purpose-built for AR-15 and flattop receiver platforms. If you're running a modern sporting rifle and need to get your optic up and forward without a traditional two-piece setup, this aluminum mount delivers the strength and lightweight profile that makes it a solid choice for hunters and shooters who want a clean, integrated aesthetic on their rifle.

Steiner machined this mount from aluminum alloy to handle the recoil and ruggedness of field use while keeping overall weight minimal—a combination that matters when you're carrying your rifle for miles or setting up for a long day at the range. The cantilever design positions your scope forward on the receiver, which gives you better eye relief and a more ergonomic sight picture, especially if you're using a magnified optic or planning to run backup irons behind it.

The 30mm tube diameter fits the majority of modern scopes, and the high mount position clears most AR handguards and accessories. It locks into any Picatinny rail, so mounting is straightforward if you're already familiar with the standard. The matte finish blends with most rifle setups and resists glare without the visual weight of glossy coatings.

Frequently Asked Questions

Will this mount fit my AR-15?

Yes, the Steiner T-Series MSR is designed for AR-15 and flattop receiver platforms with Picatinny rails. As long as your rifle has a standard Picatinny receiver rail, this mount will attach.

What size scopes does this mount accept?

This is a 30mm mount, so it accommodates scopes with 30mm tubes. It will not fit 1-inch or 34mm scope tubes.

Why choose a cantilever mount over a traditional two-piece?

Cantilever mounts like this one sit forward on the receiver as a single unit, giving you better eye relief, more rail real estate behind the scope for backup sights or other accessories, and a cleaner, more integrated look on modern AR platforms.

Is this mount high enough to clear my handguard?

The Steiner T-Series MSR is designed with a high profile, which clears most standard AR handguards. However, fit depends on your specific handguard height and profile; measure or test-fit if you have an unusual setup.
