Who This Is For
This rail section is ideal for AR-15 and AR-10 owners who run an M-LOK handguard and want to add a specific accessory — such as a pressure switch, offset iron sight, or small tactical light — at a precise location without committing to a full-length top rail.

Frequently Asked Questions
Will this rail section fit any M-LOK handguard?
Yes. The San Tan Tactical 3-Slot Rail Section is designed to the M-LOK open standard, so it will mount securely to any handguard, stock, or chassis that features standard M-LOK slots — regardless of manufacturer. Simply insert the T-nuts into the M-LOK slots, position the rail where you need it, and torque the hardware to spec.
What accessories can I mount on a 3-slot Picatinny rail?
A 3-slot 1913 Picatinny section accommodates a wide range of rail-mount accessories, including compact tactical lights, pressure pad switches, offset iron sights, laser aiming devices, and small foregrips. The slot count limits the length of accessory that will fit, so it's best suited for compact items rather than extended rifle scopes or long foregrips.
Do I need any special tools or hardware to install this rail section?
Installation is straightforward and requires only basic tools. The rail section typically ships with the M-LOK T-nuts and mounting screws needed for attachment. A torque wrench or driver is recommended to tighten hardware to the manufacturer's specified torque value, ensuring the rail stays secure under recoil without over-stressing the handguard material.
