Sig on a ruger pcc - SIG SAUER Romeo MSR 1x20 mm 2 MOA Dot Reflex Red Dot Sight

I purchased this SIG SAUER Romeo-MSR Red Dot sight to sit on a Ruger 9mm Pistol Caliber Carbine. I must say it is a perfect fit and makes the gun a hoot to shoot. The dot is easy to zero, holds it's zero well, and sits high enough that the hard sights can still be used. A great optic at a great price. Thank you Sig Sauer and Optics Planet!
