Need riser block for Mini-ACOG?

Discussion in 'Black Rifle Forum' started by JerryinPA, Nov 24, 2011.

  1. I have a very light weight pencil barrelled upper with a fixed front sight on my flat top AR.

    I have a Trijicon ACOG TA 45R-4, which is one of the "Mini ACOGS", (actually originally designed to mount on a fixed carrry handle). It is a simple crosshair with no BDC, and a LaRue Mini DOS QD LT 105 mount.

    Problem is that with only 1.5 power magnification, the front sight is much too visible through the ACOG.

    I want to keep the fixed front sight along with my Troy BUIS. There is only a crosshair, i.e. no bullet drop compensation on this model of ACOG, so raising it up enough to see over the front sight doesn't concern me.

    What kind of riser block can I use under the LaRue? Or, more importantly, is there a better suggestion?

    Thanks in advance,

  2. Eurodriver
