The Crimson Trace CTL-5108 is a premium low power variable optic (LPVO) built around Japanese ED glass, a First Focal Plane SR1-MIL illuminated reticle, and a rugged 34mm tube designed for fast shooting up close while still offering precision at distance.
Featuring a versatile 1-8x magnification range, this optic is ideal for:
- AR-platform rifles
- tactical and competition shooting
- pig hunting
- fast bush hunting
- close-to-medium range precision work
- shooters wanting true LPVO versatility.
Built with premium ED glass and fully multi-coated lenses, the CTL-5108 delivers excellent clarity, strong low-light performance, and a wide field of view at 1x for rapid target acquisition. The illuminated SR1-MIL reticle sits in the First Focal Plane, allowing accurate holdovers and ranging across the full magnification range.
The capped MIL turrets provide precise .2 MIL adjustments while maintaining a streamlined hunting/tactical profile. The optic is housed in a rugged aircraft-grade 34mm tube and is fully waterproof, fogproof, shockproof, recoil proof, and nitrogen purged for hard field use.

Why We Like It
The CTL-5108 offers premium LPVO features usually found in significantly more expensive optics. The Japanese ED glass is genuinely impressive, the FFP reticle system makes it highly versatile, and the optic balances fast close-range shooting with enough magnification for confident longer shots.
For shooters wanting a serious LPVO without paying Razor or ATACR money, the CTL-5108 represents exceptional value in a premium-feature package.
