Trijicon 3.5x35 ACOG Rifle Scope - 300 BLK Green Crosshair, Matte Finish, w/ Picatinny Adapter

The Trijicon 3.5x35 ACOG rifle scope is a compact, fixed-magnification optic purpose-built for shorter-range engagements and close-quarters combat applications. This 300 BLK-specific model pairs a 3.5x magnification with a 35mm objective lens, delivering a bright sight picture optimized for the subsonic and supersonic ballistics of the .300 Blackout cartridge. With its green illuminated crosshair reticle and matte finish, this ACOG combines the speed and light-gathering you need in confined spaces—whether you're hunting dense timber, working a home-defense setup, or running drills at intermediate distances. The included Picatinny adapter ensures straightforward mounting on any MIL-STD-1913 rail system.

Trijicon ACOGs are trusted by military and law enforcement for good reason: they're built to absorb punishment and deliver consistent performance when it matters. The 300 BLK ballistic reticle is calibrated to that cartridge's trajectory, so your hold-over and windage adjustments are dialed in from the start. The green illuminated reticle is visible in low light without requiring batteries—Trijicon's fiber-optic and tritium system keeps the reticle glowing in near-total darkness and shines brightly in daylight, giving you one less thing to worry about in the field.

This is a fixed-power optic, which means no magnification ring to adjust mid-shot, no parallax knob to dial, and no complexity—just point, aim, and shoot. If you're running a 300 Blackout and want a battle-proven scope that handles both subsonic suppressed fire and full-power loads without flinching, this ACOG is a no-nonsense choice.
