Description

This Primary Arms rifle scope is part of the SLx optics line. SLx optics have built a reputation for innovation, reliability, and value. All SLx optics undergo rigorous field-testing during development to best serve you in any environment. The SLx 1-6x24mm SFP Gen IV Rifle Scope is the latest iteration of their best-selling carbine optic, incorporating a fully upgraded optical system, an integrated dovetail throw lever, and all-new ACSS reticles. With superior glass clarity and swift magnification controls, you’ll always have the power to identify, range, and engage your targets with unrivaled precision. This 1-6x low power variable optic features the ACSS NOVA 5.56/.308 Reticle. The ACSS NOVA is a purpose-built reticle that leverages a high-efficiency fiber optic wire for Red Dot Bright illumination. With built-in target ranging, BDC subtensions, and moving target leads, this reticle provides a broad, intuitive toolset for engaging targets from close to long-range. This version of the NOVA features BDC subtensions specifically calibrated for 5.56 and .308 ammunition allowing you to easily calculate bullet drop and hit those long range shots. EXPORT CONTROLLED ITEMS: These items are controlled for export and may require an export license from the U.S. Government. Buyer acknowledges that Buyer is responsible for obtaining all export licensing authorizations and filing all export documents prior to export from the United States. A Second Focal Plane reticle means that your reticle size stays the same whether zoomed in or out. Pros: The optics are simpler to manufacturer making them more prevalent on the market and lower in cost to consumers. Cons: The reticle being the same size regardless of the magnification means the stadia marks can only be used at maximum magnification where they are accurate. At anything but maximum magnification some old school calculations will need to be made to hit the target bulls-eye.

The ACSS NOVA 5.56/.308 is an advanced BDC reticle that leverages a high-efficiency fiber optic wire for ultra-bright illumination. With built-in target ranging, full 5.56/.308 ballistic drop holdovers, and moving target leads, this reticle provides a comprehensive toolset for engaging targets at variable distances. NOTE: For Second Focal Plane (SFP) scopes, your auto- ranging and holds are for MAX MAGNIFICATION ONLY. The ACSS NOVA 5.56 /.308 features a full BDC, allowing for accurate engagements from close range to 700 yards. This BDC is compatible with 5.56 NATO, .308 Winchester, and similar cartridges. Knowing the distance to your target is crucial to using the reticle effectively. The MIL subtensions are sized to match an 18” measurement at various distances. To range a target by its width, simply hold your MIL subtensions over an 18” target and find the stadia which most closely matches its width. 1st MIL = 300yd 2nd MIL = 400yd 3rd MIL = 500yd To range your target, hold your BDC over an 18” cross-section and find the stadia which most closely matches its width. This will give you a quick estimate of the target’s distance, allowing you to compensate for drop more effectively. The ACSS NOVA 5.56/.308 reticle features built-in leads to help you engage walking, jogging, or sprinting targets. These leads are most effective at when shooting at distances between 100 and 300 yards. ACSS NOVA 5.56 Reticle Target Ranging Moving Target Leads

Buying This Turned a New Leaf in My Optic Life
Color: Black Style: ACSS Nova 5.56/.308 Fiber Wire
i assume there are 3 kinds of optic buyers. 1) the cheapos: will buy an optic off temu before landing on Monstrum because monstrum actually gets the job done 2) the chads: guys who wouldn’t look twice at this optic because they have 5 Razer HD’s at home 3) the guy who only buys primary arms, because monstrum is a budget brand, and primary arms is one of the most cost effective REAL brands. like Holosun! but for magnified optics i was #1. ive never unironically used a temu optic. but i’ve bought and used for fun. i had monstrum 1-10x28 because they are THE budget brand. $190 for an lpvo AND amount that will hold zero and work amazing. welll then i got a monstrum 1-10x24 and lets just say that’s how i found this optic. i’ve never had issues with monstrum before but i figured it was time to graduate since i got the first one ever that simply wouldn't suffice for me. well let me just say i get why guy #2 has 5 Razer HD’s at home. im turned. this SLX is the most expensive optic i’ve ever bought and i get it now. i just get it now. worth every cent. i’ll never cheap out on optics again. i have it paired to a Vortex cantilever mount. never knew how great LPVO’s could look. if this scope is out of your price point. find a monstrum 1-(X)x28 because the x24 either doesn’t let enough light in, or the glass just ain’t good enough. installation is like any other scope. the red dot can literally be used as a red dot. eye relief is good. people online complained about this throw lever being hard to change magnifications. it’s easier than any Monstrum variable optic i have. so i don’t know what they’re talking about it’s very easy. and it better hold zero for $300. have a good day. ... show more

This is my 3rd one
Color: Black Style: ACSS Nova 5.56/.308 Fiber Wire
Best LPVO for under $500. I now own 3 of these scopes. One on my 300 Blackout, my 5.56, and my 6.8 SPC.

Great low power scope for the money
Color: Black Style: ACSS Nova 5.56/.308 Fiber Wire
This was a big upgrade for me from PA's budget option. Clear glass and smooth dials. I do wish the clicks were a little easier to feel but this has not caused an issue with mt POI on any occasion. Overall a great low power scope for the money and I now own two!!

Best LPVO for the money
Color: Black Style: ACSS Nova 5.56/.308 Fiber Wire
If you’re not willing to pay 1000$+ for an LPVO, then just get this one. Super durable, and it really is day light bright. Looks good and performs great.
