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

The Primary Arms SLx 1-10×28 Rifle Scope takes what is popular about low power variable optics and steps it up a notch to a larger magnification range without making sacrifices common with more traditional 10x optics. The first true 1-10x 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 the 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.
