LokPin Install Instructions

 

We recommend Magpul's Install instructions, available here.

 

Install only on the bottom and sides of the rail. Do not mount on the top near the barrel or in any location where convection heat or hot gases may come into direct contact with the LokPin or its hardware.

 

General Assembly Steps 

  1. Assemble your pin
    1. Put the bolts onto the pin
    2. Add washers (If Selected)
    3. Add Thread Locker (If available)(Blue 242 recommended)
    4. Loosely add bolts, only a few threads
  2. Slide through M-Lok rail -- KeyMod slide forward
  3. Gently tighten, Ensure t-nut is perpendicular to rail
  4. Hand Tight only! Make sure t-nut stays perpendicular to rail
  5. DO NOT over tighten!

M-Lok

 

KeyMod

For single Slot LokPins, the KeyMod alignment will be slightly off. Tighten the forward bolt first and then the rearward one. For 2 Slot LokPins, the measurements are to KeyMod Spec and will line up exactly at the front of the KeyMod hole.

The pin will still be secure. We recommend thread locker and silicone washers for KeyMod since there is less rail to hold the bolts onto.

 

Install Tips:

If the t-nuts keep spinning and will not tighten, pull up gently on the pin so the t-nut lines up in the slot. Make sure it is perpendicular before tightening further.

If the pin still pulls up, the t-nut is not in position. Loosen the bolt until the t-nut can rotate in the 90* position and then tighten.

Over tightening can force the t-nut to spin, or to dent the rail slot. Make sure it is in position and DO NOT over tighten. Let the Tread Locker and/or washers hold it in place.

If your LokPin falls out with heavy use. Consider using the OEM Magpul hardware. It will stay in place in extreme situations. (Available on Magpul's website)
