2018年3月15日 · Ruger finally got around to sending me a replacement for my defective MK4 Hunter. Here is my experience with Ruger. I spent $650 on a precision .22 pistol that had a bore that was drilled off center and found by Ruger to be defective. It took Ruger nearly a month to send me a replacement. I...

2021年5月28日 · I have some Ruger mags that say Mark III on the package. I also have Ruger mags that say Mark III & IV on the package. I also have Majestic Arms mags that say Mark II/III Universal on the package. I have all four guns, I, II, III, & …

2024年12月2日 · With the mk4, numbers 1 and 3 are your most likely culprits. Springs become slightly weaker as they achieve a set. That means their uncompressed length shrinks a little as they settle into their working length. Around 500 high velocity rounds is typically enough for this process to complete in mark pistols.

2020年12月31日 · My Mk4 suffered from various ailments, but the most maddening was stovepiping of empty cases. Really frustrating during 10 second matches! It would never stomach subsonics for more than a round or two before malfunctioning and often had stovepipe issues with Mini Mags etc. In short the Mk4 was a complete pain in the backside.

2023年10月3日 · Thoughts on which manufacturer upgrades are the best for the MK4? Tandemkross or Volquartsen? I'm wanting the usual trigger upgrades and enhanced firing pin/extractor upgrades for target and general plinking. Anyone have any recommendations for …

2019年3月18日 · Unless you are a world class match shooter, chances are that the gun is more accurate than you can be. I have the MK IV 22/45 lite; at that range, I often put out a target with dots that are about 2" in diameter.

2021年9月23日 · Again, I'm a Bullseye shooter with a Mk4 Ruger. Just exploring 'cheap' ways to reduce undesirable movements. All of the top shooters in our league use European gear at +$2000 before mods / red dots, tricked out electronic triggers, etc.

2017年9月2日 · The Ruger Mark series through the Mark III are notorious for a difficult and confusing disassembly and reassembly process. The Mark IV made that a push button process. I haven't looked for a Mark IV video, but if you're not finding one, I suspect no one has wanted to make a video where you just push one button. It would be a short video.

2017年1月18日 · congrats Congratulations on your new mark 4. I have an older 22/45 mk3 and have been having a few issues (related to the number of rounds through it). Anyway, I have had good reminders of how much of a PITA assembling and disassembling it can be, even with the mag bushing mod. hopefully I am on the good side of that now. because hearing all the positive reviews here have be

2021年11月17日 · Well I really like it, except that I'm getting 1-2 failure to fires, per mag. Even when perfectly clean. Too bad I already ordered my Volquartsen barrel, trigger & accurizing kit ahead of bringing my mk iv home and discovering this problem- they had a more extensive kit that would have helped with that.
