Frequently asked questions

Will this adapter work with my existing Shield RMSc optic?

Yes. The RFX44 is built on the Shield RMSc footprint and also accepts ACRO pattern optics. Verify your red dot's footprint before ordering to ensure compatibility.

How does the 5 MOA green dot perform at different distances?

A 5 MOA dot covers roughly 5 inches at 100 yards, making it ideal for defensive and competition shooting. At closer ranges, the dot stays precise for quick sight picture acquisition without obscuring the target.

What do I need to bring for DROS in California?

Bring a valid California driver's license or ID card, proof of residency, your Firearm Safety Certificate (FSC), and payment for the firearm and transfer fees. Looking for FFL dealer Fremont? Visit us in Sunnyvale.
