When consulting with firearms enthusiasts about their primary scopes, one name keeps popping up—Primary Arms. Having put these scopes through extensive testing, I can tell you that their innovative features really stand out. For instance, I tested the Primary Arms SLX 1-6x24mm SFP Rifle Scope Gen IV ACSS Nova and was impressed by its fully upgraded optical system and integrated magnification lever, making quick adjustments smooth and effortless.
