Product Info for Forward Controls Design LMT MARS-H PF-040 Pins

PF-040, MARS-H is a version of the AR15/M16 spec PF-040 take down and pivot pins made for LMT's MARS-H, Defender H, MWS, and KAC's SR25, M110. Machined from 17-4 PH SS bar stock and QPQ finished, these pins are 0.040 longer than factory pivot and take down pins.image

PF-040 pins can be aptly described as "reverse extended", in that they're longer on the left side of the receiver, the additional length of the take down pin doesn't interfere with ambidextrous safety operation. When PF-040 pins are pushed in from the left side, the +0.040 transforms to extra length and grasping area on the right side pin head, which combined with their silky smoothness, makes pulling the pin a cinch.

PF-040 has the same elegant and unadorned pin heads design that is in line with our design philosophy which prioritizes functionality over aesthetics. PF-040 right side pin heads (when installed on a receiver, with the muzzle pointing away) are flat, with a small 45 degree chamfer. Serrations or dimples on the right pin head would be useless, so they're completely plain. There is a small dimple on the other side of the pin head, the tip of bullets (up to 9mm) can be used to push the pins in on tight fitting receivers.

NOTE: PF-040, MARS-H pivot pin will NOT work with LR308 pattern receivers, or Armalite's AR10A. The take down pin will work on all known 308 AR lowers, but there are three major patterns, PF-040, MAR-H's pivot pin is designed to work on SR25 pattern receivers only.

Compatible with: KAC SR25, M110, LMT Defender H, MARS-H, Centurion Arms M11 7.62.

Incompatible with: LR 308 pattern receivers, Armalite AR10A and AR10B, LaRue Tactical OBR 7.62.
