Typical production AR-15 pins are ~.245" diameter and flat on the ends. They operate in .250 pin holes, and items used to push the pins occasionally slide off and can scratch your lower receiver.

This pin set is ~.248" diameter, allowing you to improve your upper to lower receiver fit, and features early Armalite / early Colt style dimples to assist in location of bullet tips or tools used to push the pins. The tool locating dimples reduce the likelyhood of scratching your lower and add a nice feature to ease diss-assembly.

Note: Some Ar15's are manufactured out of specification and are designed to have no tolerance with .245 pins. These would not be a good candidate for this part. Mil-spec uppers and lowers however typically have .006-.008" of play and these pins will remove ~.002-.003 of that play, improving fit and feel of the parts.

    Nice pins

    Published by Aaron on 9th Jun 2017

    I bought these to take out the slop between my Spikes lower and BCM upper. It helped some, but didn't fully eliminate it. I threw in some X-shims as well and now it perfect. The pins are really nice, just not quite enough for my particular rifle, though I don't know if any sized pin would have solved my issue.

    Exact same size as my Seekins Precision pins .2485

    I had a tiny, tiny bit of play between my receivers. I was hoping these would eliminate it. Turns out they are the exact same size as my original pins. They are high quality and I liked the finish better so I used them.

    Oversized takedown pins for ar 15

    Published by John Deom on 21st Jul 2016

    Great product. I had a lot of play between my upper and lower. Which bothered me since the upper and lower were supposedly a matched set. The pins took out all the play. Great idea and product.
