It is extremely lightweight and only weighs 1 pound in total. Given this, it will not add any unnecessary weight to your rifle. You will not have to worry about it being cumbersome at all.

When looking at the cost, given how high quality this scope is, it is reasonable. 

BDC Reticle

The Nikon Prostaff has a BDC reticle. This reticle will allow you to be precise and accurate when finding your target.

It is one of the best reticles available in the current market and is very impressive on the whole. 

It contains see-through ballistic circles that are unique to this Nikon Prostaff. These will help you to have a good advantage, even from a long-range.

It can also be changed to allow for better short-range shooting. It provides the best in both situations. 

It is worth noting that some users have had some trouble with the reticle after purchasing in regards to it holding zero.

Magnifying Settings

The Overall magnifying settings for the Prostaff are good. It can magnify between 3x to 9x. This is great because it means that you can focus on the target from quite a distance away.

With the longer range settings, you can hit a target up to 1000 yards away with no issues. 

The lower magnifying settings are great for short-range. It will allow you to focus accurately, even if the target is moving, you can still keep close track of it.

The setting is also maintained if your rifle recoils significantly. 

When looking at the max internal adjustments, this is 80MOA. The scope makes a clicking sound when you make any adjustments.
