ITs a good LPVO scope with a great BDC reticle. Its a great addition to my AR15. Took it out recently and zeroed at 100 yds then shot at 10"x10" plate at 600 yds. Easy to bracket your shot during switchy winds. Optics Planet was great to deal wit...

great value for the buck by dana, Verified Owner, January 14, 2024
Not perfect through all levels of the x's but does it really matter? No, it's a SFP so at least the 1x is really good. At 10x the eye box is tight, but at this X you should have a good firing position anyways. For the majority of shooters this along ...

Product Info for Primary Arms SLx 1-10x28mm Rifle Scope, Second Focal Plane (SFP)

This rifle scope is part of our SLx optics line. SLx optics built our reputation for innovation, reliability and value. All SLx optics undergo rigorous field-testing during development to best serve you in any environment.image

The Primary Arms SLx 1-10x28 Rifle Scope takes what is popular about Low Power Variable Optics (LPVO) and steps it up a notch to a larger magnification range without making sacrifices common with more traditional 10x optics. Our first true 1-10x Low Power Variable Optic (LPVO) boasts a generous 3.2 - 3.5 inches of eye relief allowing you to easily set this scope up on your rifle of choice and still features a great field of view throughout the magnification range. With the addition of an integrated magnification lever, you can quickly and easily go from a true 1x sight picture all the way up to 10x magnification for those longer distance precision shots or simply for better target identification. This is truly a versatile optic that can do it all from close quarters to long range while still only weighing 19.1 ounces at 10.5 inches long. Just like our other optics, this scope is protected by the Primary Arms Lifetime Warranty. If a defect due to materials or workmanship, or even normal wear and tear, has caused your product to malfunction, Primary Arms will either repair or replace your product.

The ACSS Griffin MIL M10-S is an all-new SFP reticle that is purpose-made for optics with a 1-10x magnification range. In close quarters, the ACSS Griffin MIL M10-S offers a bold horseshoe with a chevron tip. For long-range precision, users can leverage the full functionality of their ACSS reticle. The ACSS Griffin MIL M10-S integrates an intuitive MIL grid and both vertical and horizontal ranging stadia for quick range estimation and target engagement. Check out the manual below for a deep dive into all the functionality of this reticle.
