First Look: Primary Arms SLx 1-10x28mm SFP Rifle Scope

Primary Arms Optics has just announced the SLx 1-10x28mm SFP rifle scope, a new LPVO with a choice between two reticle options.

LPVO scopes remain a popular alternative to red dot/magnifier combo setups, offering their users relatively quick target acquisition at close ranges with the lowest magnification setting while also providing superior long-range capabilities at higher levels of zoom. The newest LPVO to come to market is Primary Arms Optics’ SLx 1-10x28mm SFP scope, offered with one of two reticle options.


The precision and durability of the new scopes were live-fire tested using a SCAR in 7.62x51mm NATO, proving they can withstand a healthy amount of recoil. The SLx 1-10x28mm SFP also features a 28mm objective lens, a 34mm tube and a generous eye box for effective rapid acquisition at lower magnification settings. Regardless of the model selected, both reticles are illuminated with 11 brightness settings including two for use with night vision.


Speaking of reticles, the SLx 1-10x28mm SFP can be bought with either an ACSS Raptor 5.56 M10S or the ACSS Griffin MIL M10S. The former features BDC, ranging and wind lead marks that are calibrated for both 5.56x45mm and .308 Winchester. The latter reticle option instead features a full MIL-grid, making it compatible with a wider range of cartridges and firearms.


Stephen Morgan, Product Marketing Director at Primary Arms Optics, said this about the new scope:

As LPVO technology gets better and better, the optics become more and more versatile…We have developed our new SLx 1-10 with the do-all, universal rifle in mind. Fast and wide at 1x and ultimate precision at 10x, it is the perfect fit for your next do all rifle build at an affordable price.

Both new models of the SLx 1-10x28mm SFP scope have an MSRP of $449.99 and are available now.
