Scope Smarts — Five Videos That Explain Optics Topics
Rifle accuracy is pointless unless you can see your target and aim precisely. That’s why good optics are so important for precision shooting — from 50 yards out to a mile and beyond. Today’s premium scopes can be very expensive — you’ll see optics costing $3000 or more on many competition F-Class and PRS rifles. This article covers important “Riflescope Knowledge”, including how to adjust for parallax, and how to properly sight-in your scoped rifle. In addition there’s a helpful video defining Minute of Angle (MOA) plus two videos showing how to mount scopes.
Rifle Sight-In Process — Start to Finish
Here Ryan Cleckner shares his process for sighting in a scoped rifle. This helpful video covers the full process: bore-sighting, 25-yard shot confirmation, shooting groups, making adjustments at 100 yards, and finding mechanical zero.

How to Adjust for Parallax
Most precision rifle scopes have parallax adjustment, but what is it and why do you need to adjust it? In this Shooting USA video, John Paul of JP Rifles defines parallax and explains why you need to set parallax correctly for the distance to your target. The video then show how to adjust parallax correctly. a process which should start with the scope’s ocular focus.
Understanding Minute of Angle (MOA)
In this video, Ryan Cleckner explains the measurement term “minute of angle” (MOA) and how to use MOA adjustments on your scope to compensate for bullet drop at varying distances. MOA is an angular measurement, used often in long range shooting, that is 1/60th of one degree of a circle. One MOA represents 1.047″ at 100 yards and 10.47″ at 1000 yards. Want to learn more?

How to Mount a Riflescope
When mounting a scope you want to use quality rings, and ensure that the scope is leveled properly. In addition, you need to adjust the fore/aft position of the scope so that eye relief is correct. Ideal scope position may be different when shooting from the bench vs. shooting prone. In this Shooting USA video John Paul of JP Rifles reviews scope mounting basics.
Scope Mounting on a PRS Precision Rifle
Here the MasterPiece Arms (MPA) Academy experts show how to mount a scope on a PRS-type tactical rifle. Special considerations for tactical shooters are discussed. The video also shows recommended tools for scope mounting operations.
