Excellent upgrade - KIDD Innovative Design LR Complete Bolt For Ruger 10/22 Scalloped Silver

The machine work, fitment, and finish of this bolt is excellent. The rear radius that pushes the hammer is very well polished. The little things that Kidd does like tool steel firing pin and extractor are definitely improvements to factory stampings. The harden pin to prevent firing pin movement will make each primer strike exactly the same every time. The scallops look great and actually reduce friction a bit... but mostly they really look cool. I have a Kidd bolt without the scallops and now I wish it had the scallops!

One thing that is different from a factory bolt is the extractor spring and plunger does not move as far rearward. If you have a TandemKross extractor tool to pull and hold the extractor plunger and spring back while removing the extractor, it won't work with the Kidd bolt. That is not unique to Kidd bolts because other aftermarket bolts I've tried are the same. It's not a big deal if you use a pin punch to disassemble the extractor components or, if you are a machinist like me, you can make one similar to the TK tool that works for the Kidd bolt.

Overall, I am very happy with the Kidd bolt and think is an excellent upgrade. There are a lot of little things that Kidd does to improve the factory bolt and they all add up to a real improvement that is well worth the cost.
