    A2 gas block pins.

    Ah, the pick of these pins was next to the gas block I ordered. I was not paying attention and ordered by mistake thinking it was the pin for the gas block. The pick was next to the low profile gas block I ordered. I did not pay close enough attention. Not worth the trouble to send back. I'm sure they will be fine if I ever do a retro build.

    I ordered the tapered pins for the site base so not much to say about quality. But the time it took to get to me was great!! Fast shipping is a very big bonus!! Thanks!

    I haven’t been to the range yet but the pins appear to fit like a glove.
