Williams Fire Sight - 602588 - Ruger® MK™ Series Bull Barrel

Bought these for the MarkIV Tactical. Was looking for a fiber optic front sight to go with the OEM black out rear and was hoping these would work. They did! Only had to make a minor elevation adjustment to the rear. Sights are good quality and super bright for easy acquision . Love them.

I wear bifocals and struggled with getting a clear view on the sight that came with Ruger Mark IV. The Williams Fire Sight was a significant improvement, particularly in lower light conditions in indoor ranges.

Had these installed by a gunsmith who did it while I waited. Second session the front orange fiber optic went missing. Although they told me there wasn't a warranty I was sent a new plastic piece that you slide in and then melt the ends to hold it in place using a butane torch (think creme brulee). No problem. With my old eyes I wish the fiber optics were a little larger diameter but overall I am pleased.

Only took a few minutes to install , great fit and finish , fiber optics are nice and clear and makes it easy to acquire the target . Great service from Tandemkross.

Had my gunsmith install these sights on my wife’s a new Ruger Mark4 Tactical pistol. Once installed she complained the sun was reflecting off the Picatinny rail. So I removed the rail and it improved the sight picture. These look like quality sights and they look good on the pistol. She is still breaking in pistol she only had a couple hundred rounds thru it and these sights are much better than the factory sights.
