I've had my new 15-22 Sport for 9 days. The extractor works fine, but has fallen out of the bolt twice. Does anyone make an extractor or extractor/plunger/spring that will stay in the bolt? I've been very lucky to have found all of the parts both times.
The Tailhook looks like it may stand a better chance of staying in: Tailhook S&W M&P15-22 Extractor Replacement Part
