CaptainACARS's Review of 2A Armament LR-308/SR-25 Titanium Takedown Pins

Pin diameter measured with a micrometer was .278-.279. Very nice pins, I would buy them again. Building an Armalite pattern (MARS-H lower and J.P. Side Charging Upper) has gone surprisingly smoothly, but finding pins that I was happy with has been the most difficult part because not all manufacturers put the dimensions up on their website, not sure why as this seems so obvious, especially with the AR-10 platform which has lots of compatibility issues. I tried J.P. Push Button and Battle Arms EPS-308, J.P. Ran .274-.275, Battle Arms ran a consistent .276. Those pins might be better in a DPMS pattern, but these 2A titanium pins were by far the best in my Armalite MARS-H lower.
