Seekins 0010650166-F 45 Deg Side Pic Rail

The Seekins Precision 45-degree side Picatinny rail gives you a clean way to mount optics, lights, or other tactical accessories to the side of your upper receiver or handguard. Built from aluminum and finished in black, this rail uses standard Picatinny slots, so it works with any MIL-STD-1913 accessory you already own or plan to add. Whether you're running a backup sight, a laser, or an offset red dot for closer-range work, a 45-degree mount lets you keep your primary optic high and centered while positioning secondary gear for quick target transitions.

Seekins Precision has a solid reputation in the AR platform world for making no-nonsense parts that hold zero and stay put. This rail is a straightforward aluminum extrusion—nothing complicated, nothing that needs constant adjustment. It bolts to standard Pic slots and gives you a solid platform for whatever you mount next.

If you shoot competition, do close-quarters drills, or just like having redundancy on your rifle, an offset 45-degree rail is a practical upgrade. It keeps your primary sight picture unobstructed while giving you another option when the situation demands it.

Frequently Asked Questions

What's the difference between a 45-degree rail and a direct Picatinny mount?

A 45-degree rail positions your accessory at an angle to the side of the receiver, which keeps your primary optic's sight picture clear and lets you use a backup sight or offset optic without obstruction. A direct mount places the accessory parallel to the rail. The 45-degree angle is popular for offset red dots and backup iron sights in tactical and competition setups.

Will this rail work with my existing Picatinny accessories?

Yes. The Seekins 45-degree rail uses standard Picatinny (MIL-STD-1913) slots, so any optic, light, laser, or sight designed for Picatinny will mount to it.

What kind of guns does this fit?

This rail mounts to any firearm or handguard that has standard Picatinny slots. It's most common on AR-platform rifles, but works anywhere you have a Pic rail interface.
