To help out with some accuracy testing of the Windham SRC, we just got in the Burris AR Riflescope (4.5-14x42mm) with AR-P.E.P.R. Scope Mount.

Today consisted of getting the scope mounted, including crosshair alignment. The tools used for ensuring proper crosshair alignment of the Burris AR Riflescope included a couple products from CTK Precision. The P3 Ultimate Gun Vise was used to secure the rifle and make leveling adjustments, while the All Purpose Gun Level ensured that the rifle was level.

CTK Precision All Purpose Gun Level Instructions:

  1. Using the P3 Ultimate Gun Vise, secure the firearm for leveling.
  2. Install the All Purpose Gun Level on a flat part of your firearm.
  3. Using the leveling legs on the P3 Ultimate Gun Vise, level the firearm. Use the All Purpose Gun Level to determine when the firearm is level.
  4. Look through your scope at a vertical reference line to see if your crosshairs are straight. If they are not, loosen the scope mount screws and align them with the vertical reference line.

The vertical reference line can be any straight vertical edge. Example: A door jam, a hanging weighted string, a vertical pole, a leveled target. Make sure your vertical reference line is perfectly vertical by checking with a carpenter’s level first. For my vertical reference line, I tied a 5.56 round to the end of a string and hung it from the ceiling.
