Check out the Aimpoint PRO Patrol Rifle Optic @

aimpoint target 24. With the information given on top of the printed Aimpoint shooting target, and by counting the number of squares between the actual point of impact and the desired point of impact on the target, you can quickly and precisely determine how many clicks you need to move the adjustment screws in order to zero your sight.

See image “Target 2”, in the column to the right here

NOTE: The number of clicks per square is determined by the distance to your target.

5. Take another shot to check that the point of impact is centered. If you still need to adjust slightly, repeat the procedure.

Question: What is a good entry level red dot scope if am just starting out?

Check out the Bushnell Trophy TRS-25 Red Dot review by Kevin: First things first, let’s establish what the Bushnell TRS-25 is NOT – it is NOT an Eotech or Aimpoint red dot sight. It is also less than 20% of the cost of either of those sights.

That being said, for the price, the Bushnell Trophy Red Dot TRS-25 3 MOA Red Dot Reticle Riflescope is an excellent sight. The construction is solid, it attached to the flat top rail of my AR15 easily and securely. The rubber lens covers, attached to each other by a small rubber cord, are sufficient for protecting the lenses from most objects and debris while remaining in place.

Question: My red dot battery keeps going dead after only a few weeks. What am I doing wrong?  You are probably leaving it on the 1 through 11 setting (increase of red dot). It needs to be set on 0 (zero) after you finish for day.  If you leave it on 1 – it will slowly drain the battery.

Question: What about the bushnell custom series reflex red-dot sight?

The Bushnell Trophy Red Dot First Strike 5 MOA Red Dot Reticle Riflescope is getting good reviews and we have seen a few shooters out at the range using it.

You can pick up one for under $120.

Question: Do you have any tips on sighting in a Deltapoint pro from Leupold?

Answer: We are currently working on a review for that scope and will post up a link when finished.
