Primary Arms CLX3 Classic 3-9x44 FFP instruction manual



The Primary Arms® 3-9x44 second focal plane scope combines traditional features with great value. Its simple design features finger adjustable turrets, a quick adjust ocular, and a simple duplex reticle. The second focal plane design keeps the reticle the same size at any magnification. The 3-9x44 Classic is a great basic rifle scope for rimfire up to 5.56 NATO caliber.

Your 3-9x44 SFP scope comes with an adjustable diopter ring that must be set to match your eye. Located at the rear of the eyepiece, it is marked simply [+ 0 -]. The diopter ring changes the focus of the reticle as you see it inside the scope. It does not change the focus of objects that you look at through the scope. Setting the diopter is the critical first step to successful precision shooting. You can set the diopter before you have even mounted the scope in its rings.

  1. Turn the Power Ring to its highest setting, 9x, and point the scope at a bright, featureless background such as blue sky or a blank white wall.
  2. With your head in position behind the scope’s ocular, look at the wall or sky instead. If you look through prescription glasses when shooting, wear them now too. After 5 or 6 seconds, close your eyes.
  3. Now open your eye, glance through the scope and immediately see if the reticle is sharp or blurry. If you notice that the reticle seems blurry at first and then suddenly sharpens, your eyes have focused on the reticle itself instead of looking through the scope. You must adjust the diopter ring and try again.
  4. If the reticle was blurry, turn the diopter ring and repeat the process again. The process will take multiple adjustments. Each time you repeat the process, ask yourself if the reticle was sharper or more blurry than before. The final adjustments may be very fine. If your eyes get watery or tired, walk away for a bit and come back to this later.
  5. Once the reticle appears sharp as soon as you glance through the scope, the diopter is set for your eyes. Everyone’s eyes are slightly different, so the ideal adjustment changes from person to person. Many shooters will mark their correct diopter position with a little dab of paint or fingernail polish next to the 0 mark, in case the ring gets turned accidentally later on. Others will apply electrical tape around the diameter of the ring to hold it in place.

Resetting Turret Position

You can reset your turret positions to read “zero” after sighting in your rifle. First, remove the turret caps. Using a 1.5mm Allen head wrench, turn the three locking screws on the outer turrets counterclockwise and remove them. Carefully pull the outer turret straight away from the scope tube until it comes completely off. Line up the 0 mark with the center line underneath, and press the outer turret straight towards the scope tube to reinstall. Finger pressure is all that is needed. With the outer turret reinstalled, re-tighten the locking screws. Do not over torque the locking screws.
