The TK Extended Bolt Lock is a very handy mod in that, the factory lock is borderline useless. In fact, the first time I lit my 10/22 up at the range, and was advised by the range officer to stop firing, secure all firearms and lock open your bolts . I had to be shown where the bolt lock was on it! The TK Bolt Lock is very handy and user friendly, most importantly - their installation video makes it a very doable DIY project

I had to wait until these were back in stock. I ordered 2 and they came in a short time. I installed both in less than 5 minutes. One went into my custom Ruger rimfire steel challenge rifle and the other will go into my PLR rimfire rifle that I am building. I watched Bill "Making good guns great" video several times. Bill, I would watch your videos anytime. You must have taken that lime green 10/22 apart so many times. If you folks are thinking of upgrading your 22lr, you cannot beat Tandemkross for parts and service. Watch Bill's videos. Tandemkross, you will hear from me again!

Works exactly as it is supposed to. Easy to install, followed instructions on YouTube. Actually it was fun and rewarding to be able to do it myself.

Best part I ordered so far! 2 needs met in one part order. The slight hit function is so nice to have vs a gunsmith machining out the v, and the bolt atch/release button is easier to find and use without looking. Before that the button was hard to locate and used a fingernail to engage- not fun. Easily installed myself using videos.

This thing is awesome - so much easier to operate than the factory mechanism. Definitely worth the price! Installation is simple - just watch the video

I recieved this item quickly and assembled it the next day. I took it to the range and it performed flawlessly, Assembly was a breeze and I could not be any happier. Tandemkross is the company ill go to for any further mod's. Keep up the great work. "Fantastic"

excellent quality, easy install, works well

Another great product from TK. Rather than fiddling and feeling around for the bolt lock, the extended knob is right there to easily engage the bolt. It's very intuitive and looks great on my rifle. The ONLY drawback is that the extension occupies the physical space where you'd normally shove your finger to engage the OEM magazine release. It really is a minor thing and isn't an issue if you've upgraded the mag release lever to a TK Fireswitch or similar. I just finished a "Frankenstein" 10/22 from previous project parts when I noticed this. So, I'll be upgrading the mag release on this rifle too !

After more than 25 years of cussing the thin blade bolt lock on my 10/22, I recently purchased your "Bolt Keeper" Extended Bolt Lock. Using your easy-to-follow descriptive video, it was installed in less than 30 minutes. Now I can lock the bolt back & also slingshot the bolt into battery in a flash. Why hasn't Ruger made this much-needed improvement decades ago. To the average plinker or Rimfire Challenge shooter I highly recommend the "Bolt Keeper".
