Primary Arms AutoLive Battery Cap - Black

The Primary Arms AutoLive Battery Cap brings AutoLive motion sensing to older and other brands' optics. The cap turns the illumination on the moment you pick up the firearm and off when it is left still, extending battery life.

It is low profile and fits, among others, Primary Arms SLx 1-8x24 FFP, SLx 1-10x28 SFP, SLx 1-6x24 SFP Gen III/IV and SLx 1-6x24 FFP, plus Sig Tango6 MSR 1-6x24, Vortex Strike Eagle 1-6 SFP and Strike Eagle 1-8 SFP. The manufacturer notes third-party compatibility may change.
