The Primary Arms 1-6x24mm SFP Riflescope is a variable magnification riflescope designed for use on rifles for hunting, target shooting, and tactical applications.

It has a magnification range of 1-6x, which means it can be adjusted to provide a view that is 1 to 6 times the size of the object being viewed.

The Primary Arms 16x24mm sfp optic competes directly with the Vortex Strike Eagle in magnification and price.

Newer Model Available

Primary Arms has released a Primary Arms SLx 1-6×24 Gen IV. We have done a complete review of the latest model.

Primary Arms 1-6 Scope

I recently changed out my Primary Arms 3x Prism for this Primary Arms 1-6x LPVO and I must say, it was the right call.

Don’t get me wrong, I love the 3x Prism, it is a fantastic optic that served me very well.

But knowing a 16″ AR-15 can reach much further than what the 3x allowed me to see comfortably, I knew it was time to upgrade ole’ green!

First Impressions

When I first pulled the Classic Series 1-6 out of the box it felt lightweight, solid, and overall well-built.

The throw knob does not come installed and the instructions don’t lay out exactly how it works. However, it’s not rocket science, and if you can’t figure out how to install it by just looking at it… maybe… don’t use firearms.

I kid… I kid.. (kinda) but it comes with a threaded knob and a single screw with a hex key for the screw. It’s pretty obvious where it goes and how it works.

Once the throw knob is installed it’s great. I really like the finish on Primary Arms scopes, including this 1-6.

Materials

Like most of the LPVOs on the market, the Primary Arms Classic series scopes are built out of aluminum and coated.

The coating feels solid and the laser etching under the optic with all of the optic information is well done.

All of the turret caps are extremely well built and also made from aluminum, I really like the quality of the small details on these scopes.

Weight

The weight without mount clocks in at just 17.21 ounces. I personally went with the Primary Arms Cantilever mount on this scope, which I think makes the cut as one of the best LPVO mounts on the market.

Most of the added weight will likely be in the mount, depending on the mount you purchase. Either way, this is not a lot of added weight to a full-length rifle system.

Mounting the Optic

Before you point out the fact that the mount is more expensive than the optic itself in the comments, I know.

But a $2,000 scope isn’t worth a hill of beans without a quality mount. So my theory on optics mounting, even cheap optics, is to buy a quality mount from day one.

The best part about buying a quality mount from the get-go is the fact that the mount will travel. So when you upgrade your LPVO to one of the best LPVO’s on the market you don’t have to turn around and buy a quality mount to go with it, you already have it.

Reticle

The reticle on this 1-6x is extremely simple. The duplex dot features classic crosshair and a simple dot in the middle of the crosshair.

The dot is the only thing on the reticle that will illuminate which I like because it’s subtle and doesn’t block your view but adds a nice touch to help with target aqcusition.

Second Focal Plane vs First Focal Plane

You may be wondering what is the big deal about focal planes and what the difference is between the second focal plane and the first focal plane.

The Classic Series 1-6 LPVO has a second focal plane (SFP) reticle, which means that the size of the reticle, or crosshairs, does not change as the magnification is adjusted.

The reticle is located on the second focal plane, which means it is placed behind the image-forming lens and appears to the eye to be a fixed size.

Reticle Brightness

There are 11 settings of reticle brightness that account for almost any lighting situation possible.

Dusk, full day, or dawn, the brightness adjustment has you covered.

LVPO Adjustment

It also has a zero reset windage and elevation turret system for easy zeroing and quick adjustments.

The adjustment is covered under two turret caps and requires no adjustment tools.

One nice feature is the ability to adjust these without even an empty shell or adjustment tool. The casing of the turrets has cuts that allow you to turn them with your bare hands.

Each turn is a 1/2 MOA is extremely easy to sight in.

Power Source

As mentioned above, the battery source for the illuminated reticle is a simple, single CR2032 3V battery.

You can find these batteries everywhere, but I stock up on them about once a year from Amazon and swap them yearly, so I don’t run up on dead batteries.

Durability

The Primary Arms 1-6x24mm SFP Riflescope is built with a durable aluminum housing and is water, fog, and shock resistant.

It has a multi-coated lens for improved image clarity and brightness, and it comes with a fast-focus eyepiece for easy and quick reticle focus.

Final Thoughts

I like this optic for $200. I think it’s a value considering it has a Lifetime warranty and is backed by Primary Arms.

I have had a lot of luck with their support team on a few minor screw issues on some of their pistol red dots.

If you are in the market for an affordable, quality, simple LPVO you should consider the Primary Arms 1-6×24 SFP.

Overall, the Primary Arms 1-6x24mm SFP Riflescope is a versatile and reliable optic that is suitable for a wide range of shooting applications.

What is the difference between FFP and SFP?

In a telescopic sight (also known as a scope or a riflescope), the first focal plane (FFP) and second focal plane (SFP) refer to the location of the reticle, which is the crosshairs or other aiming point used to aim the scope.

In a first focal plane scope, the reticle is located in front of the erector tube, which is the mechanism that moves the reticle in relation to the eyepiece. As a result, the reticle’s size appears to change as the scope magnification is adjusted. This can be an advantage because it allows the user to use the reticle to accurately range the target or measure the size of the target at any magnification setting.
In a second focal plane scope, the reticle is located at the rear of the erector tube.

As a result, the reticle’s size does not change as the magnification is adjusted. This can be an advantage because it allows the user to use the same size reticle at all magnification settings, which can be more consistent and easier to use. However, the reticle cannot be used to accurately range the target or measure the size of the target at different magnification settings.

Both first focal plane and second focal plane scopes have their own benefits and drawbacks, and the choice between them depends on the specific needs and preferences of the user.
