Howdy, y'all, greetings from the Lone Star State! As the title implies, my first post seeks some assistance with my new Tippmann Arms M4-22 Rifle. But first, a little backstory.

I've owned a Ruger 10-22 for about 40 years, and recently decided to try an AR style .22LR firearm, the S&W M&P15-22. The weapon malfunctioned right out of the box, and I sent it to S&W for a safety-recall replacement of the bolt and a new ejector. In the meantime, I tried both the HK416D 22 LR and the Tippmann, both of which have been much less prone to malfunction.

Based on increasing confidence in the reliability of the Tippmann and my preference for it over the other two firearms, I used it for a competition today and suddenly discovered that whenever a course of fire calls for safeing the rifle with a live round in the chamber (safety on, magazine out, and manually ejecting the round with the charging handle), the extractor fails to remove the round from the chamber.

I've searched for online discussions that might help identify the cause and decided to try the community link on the Tippmann Arms website, which brought me here.

Thanks in advance for any comments and suggestions.

Very respectfully yours,

Welcome.

First thing I'd check is the extractor engagement, with the bolt removed and a fired case, make sure the rim fits under the extractor with minimal effort.

Next is to check the extractor cut on the barrel, slip a round into the chamber and see if the rim extends over the extractor cut.

Finally, make sure the extractor cut is clean and free of debris, which could hold the extractor out away from the case rim.

Good luck

Update

Thank you again for the suggestions:

With the bolt removed and a fired case, the rim fits under the extractor with minimal effort.

With a round into the chamber the rim extends over the extractor cut.

The extractor cut is clean and free of debris.

I also loaded five snap caps into a magazine, closed the bolt to chamber the first one, and extracted all five with the charging handle.

Without having found anything to explain the original malfunctions, I'll need to test the function of the charging handle to extract an unfired round multiple times to see if I can duplicate the malfunction.

Once I've done that, I'll post an update with the results.

Tosh
