And it’s GREAT! FIRST, and MOST IMPORTANT: I stumbled across a 2 page illustrated and much simplified install procedure for the Williams rear sight on the Tandemkross web site (they sell this same Williams set). It makes the process of putting in the fiberoptic rear sight immensely easier and quicker, without the need for drifting out the entire sight from the dovetail, and saving yourself some money too if you were going to have a gunsmith install it. You only need a small flat blade screwdriver to accomplish the task. This is a huge tip! (And I love Tandemkross stuff.) It was a proverbial piece of cake, and took me less than 2 minutes to do it. Here's the link: https://www.tandemkross.com/assets/images/Instructions/Williams%20Fire%20Sight%20Installation%20Instructions%20-%20Post%20July%202018.pdf Note: according to the info from Tandemkross, this install method works only for Mark IV, Mark IV 22/45 and Mark IV 22/45 Lite manufactured after July 2018. Continuing my review: The two fiberoptic dots on this Williams set, installed as above, are at essentially the same height as the proper place for front-back sight alignment (per Ruger) on the original Ruger sight. However, there is a difference between the height of the factory front blade sight and the one that came with the Williams sights. The the factory sight at the point you’d normally line up with the rear sight, the highest point, sits 9.7 mm (3/8”) above the top center of the barrel (according to my not so expensive micrometer). The Williams replacement front sight measures only approximately 8.4 mm (about 21/64”) from the barrel top to the front fiberoptic. I worried that I wouldn’t be able to make enough of an elevation adjustment on the rear sight because of this >1 mm difference, but a trip to the range showed no problem (at 10 yards, the only distance I checked). I had also installed a rail on the top of the gun (Ruger 90623 1913 Picatinny Rail, from desertcart) for those times when I might want to put on a red dot (probably on a quick-detach mount). I worried that when the red dot was not on the rail would at least partially block the line of sight from the rear to the shorter front sight. That was not a problem either. I do have a bias for Hiviz fiberoptics, but as best I can tell Hiviz doesn’t sell a front-back sight combo for this gun, and although I could find the correct front sight I couldn’t find one for the back with a total cost close to what I paid for this Williams set. I'm completely satisfied with this purchase. Review: #1 - Very good part ## Features - Compatibility: Designed specifically for Ruger MK II, III, or IV “Bull Barrel” pistols.

I have a 22/45 MK 2 and they fit. Try contacting the manufacturer. They were very helpful when I had a question. **Q: Will this fit a Zastava M57 tokarev with some adjustments?** A: No. See the answer about the TX22 **Q: Will this fit on a Taurus TX22 competition?** A: You need to buy sights made for that gun. This front sight is curved at the bottom to fit the contour of the Ruger Mark series barrels described in the specifications. The height is correct to mate with the rear sight on those particular models. These are excellent sights, but inappropriate for the Taurus. I own a TX. They don it fit. **Q: Does this set of sights come with the mount screws?** A: It has been a while since I placed the order but I believe it did come with mount screws. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great --- and MUST READ easier installation tip *by M***R on January 12, 2021* I bought this to go on a new base model Ruger Mark iv 22/45 (not the LITE).

Documentation did not say it would fit a Ruger MKI with a bull barrel but it does fit perfectly. The old sight drifted right out, the new right in, using a nylon hammer. (Note: the new sight top can be disassembled and used on the base of the old sight without need to drift out/in the old/new sight base. Just remove the roll pin on the sight.) The two set screws for the dove tail lock are seriously too small. It took me longer to find that tiny wrench than it did to install the entire sight package. Front sight uses the factory screw and fits the bull barrel perfectly. Use of Loctite recommended. I had considered the TruGlow sights, since they have a slightly bigger light tube set up. Easier to pick up by older eyes. They did not have a package set to fit my gun and the price for front/back sight combination was more than this sight. The Fire Sight is actually pretty bright out doors in light so it will meet my needs for varmint control around the homestead. ## Frequently Bought Together - Williams Adjustable FireSight Set for MK-2,3,4 Bull Barrel Models (602588) - Hilljak Mini Magazine Speed Loader Designed to fit Ruger Mark I II III IV 22/45, Smith & Wesson Victory, Browning Buckmark 22LR, Quickie Loader - Bolt Racker Handle Compatible with Ruger Mark III, IV, IV Ruger Mark 3, 4 Lite Pistols -Harden-Aviation Aluminum --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.kw/products/186706425-williams-gun-sight-ruger-mk-ii-iii-or-iv-22](https://www.desertcart.com.kw/products/186706425-williams-gun-sight-ruger-mk-ii-iii-or-iv-22) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-23*
