I bought a few 223 extractors. On the first photo is a 7.62x39 bolt, the other a Grendel bolt.
Notice how the extractor impinges into the bolt face. The extractor on the 7.62 would mostly fail to snap over the rim.
I looked at an AA bolt and noticed an extended taper on the face so I made the extractor faces look like the AA bolt with a dremel tool.
The second picture only shows one modified. I also did the second one later.
Bolts are reversed left to right in each photo. Sorry.
They both now function to manually feed and eject a cartridge. I didn't have problems before with the Grendel unmodified.
I did not try this in autoloading mode. Over and out.
