Primary Arms SLx 3x MicroPrism Scope with Illuminated Red ACSS Raptor 7.62x39/.300 BLK Reticle - 710040
Product Description
Equipping an agile modern sporting rifle, dynamic short-barreled rifle (SBR), or compact AR pistol variant chambered in harder-hitting intermediate rounds often reveals a severe physical and optical bottleneck: red dot limitations. Standard 1x reflex sights provide quick close-quarters tracking speed but fail to resolve distant targets or supply precise holdover points for slower, heavy-hitting projectiles like the 7.62x39mm or .300 AAC Blackout when distance stretches out. Furthermore, shooters with astigmatism experience fuzzy dot distortion that compromises raw precision, while variable scopes add massive, top-heavy weight that destroys field agility. The Primary Weapons and Electro-Optics division at Primary Arms completely eliminates these constraints with the **SLx® 3x MicroPrism Scope**, packaging an advanced, illuminated prism engine calibrated specifically for heavy intermediate trajectories into a miniature housing smaller than a standard red dot.
Precision-machined from high-tensile 6061-T6 structural aerospace aluminum alloy, the SLx MicroPrism delivers exceptional structural stiffness that actively absorbs heavy drop impacts and violent, low-frequency cyclic recoil impulses. The entire aluminum substrate is treated with a uniform, non-reflective hardcoat anodized black jacket that repels chemical bore solvents, trail moisture, and carbon grime. At its core is an advanced, multi-coated glass prism system with a 23mm objective lens that bypasses the complex lens arrays of traditional scopes, delivering an incredibly wide field of view and massive eye-relief windows into a tiny 2.95-inch blueprint. Because the reticle is physically etched directly into the glass matrix, users with astigmatism experience a perfectly crisp aiming picture that remains 100% visible in black even if your battery pool drains completely in the field.
In high-stakes live-fire deployments or demanding tactical training strings, this optics-ready platform delivers absolute downrange authority via the world-renowned **ACSS® Raptor 7.62x39/.300 BLK Red Reticle**. This advanced ballistic system features a sharp central aiming chevron flanked by an intuitive, step-by-step bullet drop compensation (BDC) ladder, wind leads, and moving target indicators calibrated precisely for both supersonic and subsonic 7.62x39mm and .300 Blackout ballistics. Fine corrections are managed through low-profile, click-adjusted 0.25 MOA turrets that track smoothly. Driven by high-efficiency AutoLive® motion-sensing illumination, the brilliant red reticle sleeps during staging cycles and snaps awake the moment tracking motion is initiated, guaranteeing day-bright visibility across 13 manual settings.
*Armorer Bench Notes & Technical Maintenance Guidance: The Primary Arms 710040 MicroPrism features a specialized unibody base design that is fully cross-compatible with standard Trijicon Mini-ACOG format mount blocks, allowing operators to easily integrate it with premium aftermarket quick-detach levers or high-end carry handle mounts. The package includes an elite, heavy-duty multi-height mounting kit that allows for up to 8 distinct mounting height configurations to accommodate absolute co-witness, lower-1/3 co-witness, and ultra-tall centerlines on standard 1913 Picatinny rails. When assembling the base block, utilize a calibrated inch-pound torque wrench to tighten the primary cross-bolts to exactly 35-45 in-lbs to guarantee a rock-solid mechanical anchor against forward-recoil impulses. Adjust the adjustable fast-focus rear diopter ring until the ACSS chevron profile resolves to sharp clarity before initiating your live-fire zero at 50 or 100 yards. The AutoLive system is fueled by a single common CR2032 coin cell; during routine seasonal bench care, ensure the battery cap is sealed tight against its O-ring track to preserve its absolute IP67 fully waterproof and nitrogen-purged fogproof rating.
Key Features
- Ultra-Compact Micro Footprint: Packs a powerful 3x fixed magnification system into a micro 2.95-inch housing that weighs a mere 7.95 ounces to trim down nose-heavy bulk.
- 7.62x39/.300 BLK Specific BDC: Proprietary red illuminated BDC reticle features specific ballistic holdover paths optimized to manage supersonic and subsonic arcs.
- AutoLive® Motion Detection: Advanced motion-activated illumination tracking automatically cuts battery draw during static storage and wakes up instantly when the weapon is moved.
- Mini-ACOG Footprint Compatibility: Features an industry-standard Mini-ACOG mounting pattern at the base, ensuring vast aftermarket mounting configuration support.
- Astigmatism-Corrected Optics: Prism glass engineering projects a permanently sharp visual plane, completely eliminating the fuzzy dot starburst effect common to reflex optics.
