If you're experiencing extraction or ejection issues with your 10/22® style rifle or Mark Series pistol, the PRP® "Delta" extractor kit could help you solve the problem.
Due to the wide variation of manufacturing tolerances between the many brands of rifle components and rimfire ammunition, your extractor may not engage & hold a rimfire case properly to insure reliable functioning. Excessive gap or loose tension between the bolt, extractor & case can lead to non-extraction, erratic ejection, or the dreaded "stovepipe" jam.
The PRP® "Delta" kit contains 3 extractors of different front-back length (#1-factory, #2-.005" short & #3- .010" short) and an integrated tool to facilitate removal & installation of the extractor in your bolt. This will allow you to tune the extractor engagement specifically to your combination of bolt headspace & ammo case rim dimensions, giving you a more reliable firearm. After you tune your extractor, you can keep the tool in your kit and use it anytime you need to do a detailed disassembly for cleaning.
