Bolt Racker Handle Compatible with Ruger Mark III, IV, IV Ruger Mark 3, 4 Lite Pistols -Harden-Aviation Aluminum

If you don’t have one of these for your MarkIV, I strongly encourage you to get one.The instillation wasn’t necessarily easy, but once I stretched it out a little (and I mean a very minor amount) it slid right on. Has stayed on through hundreds of rounds. Looks good, feels good, and is of good quality.Very good price compared to the competitors and quick shipping time. Honestly I mean this, if you have one of these pistols, you might as well pick this up. It makes FTF/FTE’e much more manageable. Saves ya from a pinch and imo works better than the charging handle accessory that other sites sell.

Fit on my ruger mark 4 perfectly. Feels like a solid unit and it works awesome. Makes it easy to charge the pistol and keep fingers from getting pinched

Just a note, watch the video on installing. Worked good but did have to use a small screwdriver to open spacing

Make sure it has slanted grooves on the bolt (MK III & IV) excellent grip. great fit and good value.

High quality

Very nice, similar to the more expensive product I'm sure you've seen. Watch the install video. Try lining it up the way they show you a couple times and then turning. Take this product's machine bolt out first to remove any tension, and then once you have this ring installed on the weapon's bolt pull, reinstall the machine bolt and tighten it with the provided allen key. When you get it right the ring goes on easily so if you're having trouble start over and try again. You should not experience friction or difficulty in installing. Should take you 30 seconds to get on. Great fit, solid product, easy installation.

You probably heard good reviews about the tandemkross halo and came to amazon to try and get one, then found this, right? Well let me save you the trouble. DO NOT USE THIS. I tried it for almost a month and it causes failure to eject about 50% of the time with cci standard.But, you ask, if the TK halo is so good, how can this be any different? Well let me tell you, this is ~28grams added to the bolt, the TK one is ONLY 11 !! What kind of witchcraft they did? I don't know, but it works perfectly unlike this one.In short:This thing makes my ruger fail to eject at least 3 times a mag. It's probably the extra weight. Do not use.

very good quality. Easy to install. Fairy light weigh.
