PF-040 (Pins, Forward Controls, 0.040) is a set of elegantly simple, and superbly crafted AR15/M16 pivot and takedown pins. Machined from 17-4 PH SS bar stock and QPQ finished, these pins are 0.040 longer than TDP spec pivot and takedown pins.
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 their 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 may not work “PDW” stocks that have bars overlapping the take down pin holes.
PF-040 may be shipped with the old PWA-040 instructions card, the name under which it was sold up till February 2019. The pins are identical, Forward Controls acquired the rights to the pins in Feb. of 2019.
