Q
G4, guest, from AL, United States, asked on March 08, 2022

Can this sight be used on a Ruger 556 with the factory front post on the barrel?

Expert Answer
A
Answered by Hunter, Gear Expert, from OH, United States, on March 28, 2022

You could potentially cowitness the SightMark Ultra Shot R-Spec Reflex Sight with an A2 front sight post on a Ruger AR556. However, if you are going to continue using that front sight I recommend using a riser with the SightMark Ultra Shot R-Spec Reflex Sight.

The SightMark Ultra Shot R-Spec Reflex Sight can be used with the Sightmark 3x magnifier. The magnifier will work almost any reflex sight except for prismatic optics.

We do not ship out used or refurbished units. This is likely from recoil testing during our QC process. Reach out to qualityassurance@sellmark.net for warranty assistance.
