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. Does not include detents or detent springs.

    Dimpled pins

    These appear to be solid pins with a large consistent dimple. Far better than standard pins.

    Really nice pins.

    Purchased the Pivot/Takedown Pin Set from Griffin Armament to hopefully tighten up a loose AR15 a little bit. Put a micrometer on the new pins and they are dead on .248". Unfortunately so are my existing ones. So the main reason for the new pins was out the window. BUT, they are nice looking pins and I really like the dimple feature so they are going in the AR anyway. Happy to have them at what I think is a really good price.
    These aren't my first Griffin Armament products and they won't be my last.

    These oversized take down worked beautifully. We shot for groups without and with and with the tighter pins, the AR shot 25% better on the same range on the same day with the same ammo. A great and inexpensive upgrade.

    Have bought 4 pairs of these. They all measure out as advertised. Would be great if the offered even larger diameters e.g. .250, .251, etc.

    These are a must if you have a sloopy AR. Tightens things right up.

    The pins reduced the wobble or ( slop) enough to make me feel better about the upper and lower fit. Is it going to take all the wobble away? No, but it does tighten it up enough to ease your mind. The dimple in the pin is a nice touch. Overall I’d re

    Very nicely finished - almost too nice.

    Fit my carbine perfectly with the .248 diameter. Slightly longer length and the dimpled ends are a bonus

    Takedown Pin Set

    Published by rick simes on 8th May 2023

    I had a LMT SBR lower and BCM upper that fit horribly. In fact, every upper I tried fit poorly. I know it doesn't matter for reliability or accuracy, but man was it bothersome. Tons of play in every direction, noisy too. I bought these pins as a last resort, and didn't think it would really make any difference. Wow, did it make a difference! Know the fit is snug, no more wiggling around and clanking. Pins are smooth in/out, no binding. Unbelievable what a few thousandths diff in dimensions made. Also, it doesn't mention that the pins are slightly longer too which I like for disassembly. Will definitely buy more of these as needed!
