8-Point 3-9X40 Rifle Scope Q&A:

What is Truplex?

This 8-Point 3-9X40 rifle scope has the Truplex reticle that features a cross that reaches all the way to the top, bottom, left, and right of the lens. Towards the middle, the cross hairs become thinner allowing you to see exactly where your point of impact will be.

All the 8-Point rifle scopes have the Truplex reticle, while most of the ProHunter line have it too.

What is the image quality like for such a cut-price scope?

The Simmons 8-Point rifle scope has fully coated optics. Each air-to-glass lens is coated at least once to improve contrast and enhance brightness for a clear and crisp image.

Simmons scopes have great clarity and sharpness when it comes to image quality, again, especially for the price range it's in. In fact, according to online reviews, there are rarely ever any complaints about it. They're praised for their quality glass.

Will the Simmons rifle scope hold a zero, even during recoil?

Yes! A legitimate concern for many firearm users is how well the scope will hold zero, even after repeated and strenuous recoil, front and back. Simmons' patented TrueZero windage and elevation adjustments have a locking mechanism system that holds the zero in place during heavy recoil.

You should note here that this type of adjustment system is a high-end feature that is definitely not seen on rifle scopes in this price range. Many air rifle and heavy caliber firearm users may also be concerned about recoil effects and the scope holding up.

As long as you properly mount your scope with the right mounting rings and base, you're good to get hunting. So, recoil-proof? Yes, sir!

What firearms can the 8-Point scope be mounted to?

Simmons thoroughly puts their rifle scopes through the ringer to ensure that they can honestly and effectively market it to all firearm users. While they do make scopes for shotguns and handguns as well, the 8-Point is aimed at the rifle user, and according to Simmons, they test it on everything.

If you're wondering whether it's going to hold up on your AR to a .270, just make sure you properly select the right mounting system and have enough eye relief for recoil clearance. I can't stress that enough.

What kind of eyepiece system does it have?

This scope uses the fast focus eyepiece system, also known as the European style system. It's actually becoming more of the norm to use this fast focus eyepiece because of how convenient it is to quickly focus in your reticle for your eyes and get a positive target acquisition faster than ever before.

Simmons calls their system the QTA, Quick Target Acquisition, and both the ProHunter and 8-Point rifle scopes have it.

Are there any other models in the 8-Point line?

The 3-9X40 model is one of four in the Simmons 8-Point line. The other models are the 4X32, 3-9X32, and the 3-9X50. They all feature the Truplex reticle, fully coated optics, and the TrueZero scope adjustment system that's a breeze to use.

Does the Simmons scope have a parallax adjustment?

This particular model doesn't have a parallax adjustment feature or side focus. You'd be hard-pressed to find this feature in scopes double the price of this one. It's typically reserved for high end rifle scopes or those with very large or high power ranges. Since it's only really needed for magnification ranges above 8X and for very long ranges, it's not typically needed for this scope.

This model also features a factory-set parallax setting of 100 yards. If it's the make-it or break-it feature for you, you may want to check out Simmons' side focus rifle scopes, such as the Predator/Varmint series or the .44 MAG line. Even these Simmons side focus scopes are still cheaper than other brands for the same feature.

Noteworthy Features:

  • QFA eye-piece for fast focus and easy target acquisition
  • Simmons' Truplex reticle for clear and crisp cross hairs in any shooting situation
  • Fully coated lenses for deep color contrast and bright images
  • Waterproof, fogproof, and recoilproof to endure even the most rugged hunting conditions
  • 1/4 MOA clicks with TrueZero windage and elevation adjustments with smooth fingertip-action control

Our Verdict on the 8-Point Scope

According to the bull's-eye, the Simmons 8-Point 3-9X40 rifle scope is a decent, little optic-if you get a good one. Unfortunately, quality control seems to be lacking when it comes to properly aligned reticles that are supposed to move when you adjust the dials. However, all optics need to be closely inspected upon receiving the package to take advantage of warranty windows. But, you mightn't get a dud, and you could be happier than ever at getting a heck of a deal of a scope!

You can trust Simmons to appeal to all your price senses. Whether it's the bottom end of the price range or the higher end, Simmons has the power to tempt all those who want an excellent deal!
