  1. Rated 5 out of 5


    solid, well made block. looks and fits great. true picatinny rail specifications, no slop. matches the finish of Anderson barrels perfectly.
    this is a receiver height block. use low profile front irons.

    High rise gas block fits perfectly and looks great. Have them on two of my AR’s. Hope they come back in stock soon since I need another one for my recent build.

    Can I use this with standard hand guards and the round hand guard retaining bracket. This is my first ar build and I’ve decided on a gas block instead of an A2 front sight.

    • Michael Johnson

      Yes you can use this gas block

    the standard GB on the Optic ready AR is not level with the upper. Is this high rise GB taller than the standard GB and will this GB match the Optic ready AR 15 and be level? I want to use Magpul BUS for my rear sight?

    • Michael Johnson

      you want to get the high rise has block so you can use the sights

    bought an optics ready kit a few months back. I have been thinking about placing some back up sights on that ar. this block would bring the picatinny rail on the gas block level with the rail on my receiver. I was wondering if you ever considered making this style gb adjustable ?

    As of today, March 31, 2018, your site states that this item is out of stock. I am working on an AM 15 project and want to keep it Anderson. Is there an expected date when this high rise gas block will be available? I’m replacing a front sight post with this but have not removed the post yet. If these are expected to be out of stock for quite a while, I will direct my build funds toward the other end of the rifle for now. Thank you! P.S. My rating is for the rifle as it sits now and for Anderson customer service, not the part I am looking for.
