Detents and Springs
PF-040 (Pins, Forward Controls, 0.040) is a set of elegantly simple, and superbly crafted AR15/M16 pivot and take down pins.  Machined from 17-4 PH SS bar stock and QPQ finished, these pins are 0.040 longer than TDP spec pivot and take down 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 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.

PF-040 can be purchased with the optional takedown/pivot detents (4) and springs (3) kit.  The odd numbers of included components probably deserve some explanation.  Even for experienced AR builders, it's not uncommon to launch the pivot pin detent into the twilight zone.  It's also fairly easy to bend the take down pin detent spring during installation of the end plate and castle nut.  So the optional detents and spring kit includes 4 detents and 3 springs to preempt losses and damages.  If you don't end up needing and using all of them at once, the kit is reasonably priced, and always good to have on hand to grow into another AR :)

PF-040 pin diameter adheres to TDP dimensions and tolerances, 0.2485 +0.000/-0.005.

Made in USA.

PF-040 may not work "PDW" stocks that have bars overlapping the take down pin holes.

Great Upgrade
They extend out long enough to make takedown a breeze, but they never get in the way. I never knew I needed to upgrade my takedown pins until I did.

Excellent pins
These are the most beautifully machined and solid pins I’ve come across. Super solid, nice and heavy which is what you want for a part like this. Beautiful nitride finish. Super positive snap in retention with the included detents, no slop at all. I would like to have these in all my lowers.

Excellent Fit
These pins fit perfect in the 11 lowers I've used them in. Having the extra length and center dimple makes this very easy to push out when breaking down the weapon without sacrificing the actual hold of the retaining pin.

Best pins out there
I had a receiver from a very well known manufacturer come with their own version of extended/ enhanced pins. Immediately swapped them for these. These are now standard on my rifles. Makes breaking the gun down to fit in bags/ clean so much easier.
