Dot in a Donut and AA Power Source with Shake Awake... What's not to like?!

Preferred Red Dot Scope

by -

I have now purchased 3 Sig Romeo5 XDR red dot scopes. The last two were installed on an AP-5 and a MP-5. It mimics the EOTECH at half the price. The shake-to wake feature and quick target access red dot with circle are must have items for a home defense weapon. It continues to be my preferred red dot scope.
