Detailed Reviews
1. HOLOSUN 507C
The Holosun 507C is one of the most reliable red dots I’ve ever mounted on a rimfire carbine. It delivers advanced solar-powered performance, multi-reticle capability, and military-grade construction — all in a compact design perfect for the Kel Tec CMR-30.
Product Specs:
- Reticle: 2 MOA dot & 32 MOA circle
- Battery life: 50,000 hours (CR1632)
- Housing: 7075-T6 aluminum
- Brightness: 12 settings (2 NV compatible)
- Mount type: RMR footprint
- Weight: 1.5 oz
My Experience:
On the CMR-30, the 507C sits beautifully low and maintains balance without front-heaviness. The multi-reticle system lets me switch between a fine 2 MOA dot for precision shooting and a circle-dot combo for rapid target transitions. Solar Failsafe mode impressed me — even in bright Arizona sunlight, the auto-adjusting reticle stayed crisp. Zero retention was rock-solid after several hundred rounds of .22 WMR.
Online Feedback:
Users frequently mention its unmatched reliability and crisp glass, even when competing against pricier brands.
Mounting:
You’ll need an RMR-compatible base or rail adapter, but the fit is snug and streamlined once installed.
