BudsGunShop.com - Use of optic sights

you would need to remove the rear sight and use a adapter plate https://outerimpact.com/shop/ruger-american-pistol-red-dot-adapter-mount-m-r-a/

So I messaged C&H precision and asked if they could mill a slide for a ruger american. And they just messaged me back.
"I'm sure we can accommodate you, why don't you shoot our milling department an email and we can sort it out for you. Customshop@chpws.com."
or you can give us a call between 8-5 EST. 912-445-5803 option 2"

No this one is not, the Ruger American model 8672 is optics ready but out of stock everywhere

Patrick, it can but you would need to us a Dove Tailed based Mounting Plate in place of the rear Sight since this is no a factory configured Optics Slide Pistol. amazon.com/Outerimpact-Adapter-Mount-Ruger-American/dp/B07WZ2M8Y7
