Primary Arms is best known for its ACSS reticle system — bullet-drop, ranging and wind-hold reticles that make fast hits at distance genuinely intuitive without dialling. At Xtreme Tactical we stock Primary Arms prism scopes, LPVOs and red dots, dispatched from our UK warehouse.
Shop Primary Arms by type: compact MicroPrism scopes in 1x, 3x and 5x, versatile SLx, GLx and PLx LPVOs from 1-6x to 1-10x, and red dot sights including the RS-10R. If a red dot smears for you, the etched prism reticles are the ones to look at — see prism scopes.
By discipline: an ACSS LPVO is a strong Civilian Service Rifle and straight-pull option, and the 1x MicroPrism works where a dot does but keeps a sharp reticle with the illumination off. See best optics for a straight-pull AR, what is the ACSS reticle and best red dot sights under £300.
Frequently Asked Questions
What is the ACSS reticle?
An all-in-one reticle combining a bullet-drop scale, ranging and wind or lead holds calibrated to common cartridges, so you hold over rather than dial. Some models use the ACSS Nova fiber-wire reticle, which stays visible with the illumination off.
Why a prism scope?
The reticle is etched into glass, so it works without batteries and stays crisp for shooters with astigmatism — see prism scopes and our astigmatism guide.
Which magnification for British ranges?
1x suits close, fast work; 3x and 5x prisms and 1-6x to 1-10x LPVOs cover most gallery, service rifle and vermin distances. Compare in best LPVO rifle scopes.
