New AA Grendel. 37 rounds through it with two failures to extract. Two cartridges stuck in chamber. New rifles ought to run. Should I just go ahead and replace the extractor? If so, any aftermarket extractors recommended?

When your two cartridges stuck in the chamber, did your extractor pull off the rim and fail to extract?? How did you remove the stuck cartridges??Comment

Clean your chamber good and then remove your upper from your lower. Lightly push a factory cartridge in your clean chamber and then point the end of the barrel up. Your cartridge should fall out or stick very little. If the cartridge sticks then you may have a chamber or head space problem. I would also check to see if your extractor has the o-ring installed. Remove the O-ring if it does and see if this helps. I have seen the O-ring create feeding and extraction problems with Grendel bolts..Originally posted by Bjorn View PostLast edited by montana; 10-25-2021, 05:20 PM.Comment

I had the same problem but I never experienced any cartridges getting stuck in the chamber. Did you experience stuck cartridges in the chamber with an oversized gas port?Comment

Yes, just now after your post. Tried three new ones and they all slide in and then just drop out with gravity. No shaking even. The rounds that failed to extract were factory Hornady 123 SSTs. The test I just did was with the same ammunition.Comment
