Saiga/Vepr style .223 caliber AK bolt.
Use as a backup to your existing bolt. This is one of the unique parts that simply cannot be obtained from the factory. However, headspace must
be checked and verified by a gunsmith prior to firing!
It is machined here in the USA (one more domestic part!) from 4340 high nickel steel, and uses an off the shelf AK-74 extractor. It comes complete with extractor and spring loaded firing pin.
These are new manufacture, and as such, may require fitting to your particular rifle. Again, this must be done by a competent gunsmith.
These can also be used in build projects.
