Trijicon RMR RM07 - Best Overall

When To Pick RMR Over Holosun 507C ? - Holosun 507C is great, but nothing beats an American made product. The RMR is much stronger and slightly more compact for conceal carry

RMR has everything the Holosun 507C offers minus the solar panel, side battery access and multi reticles cycling. In many ways the Holosun 507C has many user friendly features, but the RMR is original battle proven micro red dot serious professionals use!

Holosun 507C X2 - Best For The Money

Why people love Holosun 507C X2 - The Holosun HE507C X2 does the same thing as the original model but better. It's an affordable Trijicon RMR that almost works like the RMR without spending over $350 or $600.

Improved Sight Alignment - Slightly larger window than the RMR, aim with both eyes open on the Shadow System MR920 just like other Glock MOS pistols.

Uses RMR Footprint - Shadow System MR920 slides are made for the RMR / 507C footprint right out of the box

Battery Almost Doesn't Run Out - 50,000 hours of battery life plus solar panel backup power. This thing last so long you might forget it has a battery in it.

On Target Every Time - Large circular window helps shooter acquire the dot every time even with slightly off alignment or imperfect draw presentation 

Easier Battery Access - Swap battery right from the top without sight removal like the Leupold DeltaPoint to reduce long term wear on the mounting screws and threads

Leupold DeltaPoint Pro - Best Glass Quality

Why we pick this one - The DeltaPoint Pro 6 MOA is a new large size MOA model finally introduced to the market. The field of view is larger than RMR and similar to the SRO. This old school red dot is one of the top choices.

Extra Housing Protection - Secondary lens hood diverts physical impact completely away from the main glass frame to prevent shattering

Built In Motion Sensor - Saves battery juice when sitting at rest. It activates when sensing motion when the user picks it up.
