    Did exactly what they’re intended for. My gas block is rock solid and these are the only pins I will use on any of my rifles.

    Front sight taper pin

    Posted by Kc on Apr 10th 2019

    These taper pins are a perfect replacement. My taper pins fell out of my front site post on my AR556 and these fixed my problem. They are quality pins and work great.

    Excellent fit and finish and helped to correct a mis-aligned front sight base. I had the item in 2 days from the time it shipped!
