Primary Arms Optics

Primary Arms is best known for its ACSS reticle system — clever bullet-drop, ranging and wind-hold reticles that make fast hits at distance genuinely intuitive. At Xtreme Tactical we stock Primary Arms prism scopes, LPVOs and red dots, dispatched fast from the UK.

Shop Primary Arms by type: compact prism scopes (astigmatism-friendly etched reticles), versatile LPVO rifle scopes and red dot sights — most built around the acclaimed ACSS reticle.

Frequently Asked Questions

What is the ACSS reticle?
An all-in-one reticle combining a bullet-drop scale, ranging and wind/lead holds calibrated to common cartridges, so you hold over rather than dial.

Why a prism scope?
The etched reticle works without batteries and stays crisp for shooters with astigmatism — see our prism scopes.
