The Trijicon ACOG 6x48 Rifle Scope Chevron .308 Red Reticle (SKU TA648-308) is the long-range ACOG: fixed 6x magnification, a 48 mm objective and a red chevron bullet drop compensating reticle cut for .308 Winchester and 7.62 NATO, lit by fibre optics in daylight and a tritium lamp after dark with no battery of any kind.
How It Compares
This is the biggest ACOG Trijicon build, and the reason for the 48 mm objective is the reach: the holds run out along the M80 trajectory to 1,312 yd (1,200 m), which is a long way past what the 4x32 models are cut for. The same reticle with a green lamp is the ACOG 6x48 Chevron .308 Green, the red horseshoe dot swaps the chevron for a horseshoe, and the chevron with a factory-fitted RMR adds a red dot on top for close work. There is also the M240 horseshoe dot cut for the machine gun. Browse all rifle scopes, the Trijicon ACOG rifle scopes range or the full Trijicon optics range.
