Primary Arms Optics Announces New MD-RB-AD-ACSS Red Dot Sight

HOUSTON, TEXAS-( Primary Arms has combined our popular MD-RB-AD micro red dot scope body with our famous ACSS-5.56 reticle. The MD-RB-AD microdot has proven exceptionally tough since its introduction in 2017.

Many have asked whether our Advanced Combined Sighting System technology can be incorporated into a Primary Arms micro dot, and the MD-RB-AD-ACSS is our answer: “Yes!”

The center chevron is larger than a 2 MOA dot to grab the eye for instant acquisition, yet it is also more accurate, because the chevron tip provides an infinitely small aiming point that never obscures the target. In addition, the ACSS reticle offers auto-ranging, bullet drop compensation, and moving target leads.

Pairing up MD-RB-AD-ACSS with a 3x or 6x magnifier extends the effective range of the micro dot equipped rifle far beyond what is possible with an ordinary micro red dot sight, without giving up any of the advantages red dot shooters enjoy in fast close quarters shooting.

Available anodized in matte black, the MD-RB-AD-ACSS is priced at $159.99.
