True North Concepts builds a focused line of optic risers designed for shooters who want their red dot or magnified optic locked at the right height without flex, wobble, or lost zero. Every optic riser in this collection is machined from 7075-T6 aluminum, finished in hard-coat anodize, and built around an integrated recoil lug and steel Picatinny clamps. This gives you a stable platform that holds zero on any standard Picatinny rail across duty, competition, and precision rifle setups. Browse the STRIX-9 and STRIX-16 optic risers below.
A quality optic is only part of the equation. Mounted too low or on a riser that shifts under recoil, your red dot sits off the optical centerline, slows your target acquisition, and can drift off zero from one string to the next. A purpose-built optic riser solves that by holding your optic at a repeatable height on a platform that does not move.
True North Concepts builds its risers in two footprints for different setups and user preferences. Both the STRIX-9 and STRIX-16 sit at a 0.625 inch riser height that brings your optic to the optical centerline for faster reticle acquisition and a heads-up shooting posture. The STRIX-9 runs a compact 9-slot Picatinny rail that mirrors standard AR upper receiver slot spacing, keeping the footprint short for red dots, compact prisms, and lightweight magnifiers. The STRIX-16 runs a 16-slot rail with two extra rearward slots, giving full-size LPVOs and magnifiers the room to mount further back for better eye relief. An integrated recoil lug seats in the recoil slot on your upper receiver, and steel Picatinny clamps lock the riser down to hold zero through repeated rounds.
Each optic riser in this collection is built to deliver the kind of steady, repeatable alignment that duty use and serious training demand.
The STRIX-9 is the compact optic riser, running a 9-slot Picatinny rail that mirrors AR upper receiver slot spacing for red dot sights, compact prisms, and lightweight magnifiers.
The STRIX-16 adds a 16-slot rail with two extra rearward slots, giving full-size LPVOs and magnifiers room to mount further back for better eye relief.
Both risers share the same 0.625 inch height, integrated recoil lug, and steel Picatinny clamps, and the two pair together when a rifle setup needs more rail real estate.
Each riser is precision-machined from 7075-T6 aluminum for high strength at a low weight, with the STRIX-16 coming in at just 4.5 ounces.
A Type III hard coat anodize finish adds protection against abrasion and corrosion for reliable performance in the field.
Both risers are designed and manufactured in the USA and are Berry Compliant for military, law enforcement, and federal end-user contracts.
Steel Picatinny clamps lock each riser to any standard Picatinny rail, letting the end user torque the screws down without stripping threads.
The reversible design lets you flip the riser so the recoil lug seats in the opposite direction depending on your preferred setup.
Both risers work with a red dot, a holographic sight like an EOTech EXPS, a magnifier, or a compact prism, and clear most night vision device and gas mask configurations.
The 0.625 inch riser height places your optic on the optical centerline for faster target acquisition and a more natural, heads-up head position.
That height gives most shooters an absolute co-witness with standard iron sight heights, keeping your backup iron sight in the same sight picture.
Raising the optic also improves clearance when running a helmet and night vision, adding better awareness behind the gun.
The risers in this collection were not built as generic spacers. True North Concepts was founded by combat veterans and engineers gear to perform under real use, and the STRIX line reflects that standard. Law enforcement officers, military personnel, and serious competition shooters rely on these optic risers to hold zero and keep the optic exactly where they need it round after round.
The STRIX-9 and STRIX-16 give shooters a repeatable optic height on a platform that does not shift under recoil. The integrated recoil lug drops into the recoil slot on your upper receiver, and the steel Picatinny clamps anchor the riser for solid zero retention. The reversible 0.625 inch height puts your red dot or magnified optic on the optical centerline for quick target acquisition and unwavering stability behind the gun.
For shooters building a carbine, a duty rifle, or a precision setup, the STRIX risers provide the alignment and mounting freedom needed to run any optic cleanly. The True North Concepts riser selection keeps both the STRIX-9 and STRIX-16 in stock and ready to ship.
True North Concepts carries two purpose-built optic risers: the STRIX-9 and the STRIX-16. The STRIX-9 runs a compact 9-slot Picatinny rail for red dots, compact prisms, and lightweight magnifiers, while the STRIX-16 runs a 16-slot rail with two extra rearward slots for full-size LPVOs and magnifiers that need to mount further back. Both share a 0.625 inch height, an integrated recoil lug, steel Picatinny clamps, and 7075-T6 aluminum construction.
The main difference is the length of the Picatinny rail. The STRIX-9 uses a 9-slot rail that mirrors standard AR upper receiver slot spacing for a short, low-profile footprint, which suits red dots and compact optics on shorter uppers. The STRIX-16 uses a 16-slot rail with additional rearward slots, giving magnified optics the room to mount further back for better eye relief. Both risers run the same 0.625 inch height and the same recoil lug and clamp system.
Both the STRIX-9 and STRIX-16 sit at a reversible 0.625 inch riser height. That height brings your optic to the optical centerline for faster reticle acquisition and gives most shooters an absolute co-witness with standard iron sight heights. It also raises the optic enough to improve clearance when running night vision or a helmet setup.
Yes. Each riser uses an integrated recoil lug that seats in the recoil slot on your upper receiver, along with steel Picatinny clamps that lock the unit to the rail. Together they anchor the riser and hold zero through repeated rounds, supporting consistent target acquisition shot after shot.
Yes. The low-profile 0.625-inch height clears most night vision device setups and works behind a gas mask for shooters running clearance gear. Both risers are also Berry Compliant and made in the USA for military, law enforcement, and federal end users.
