It has taken quite some time to piece these complete bolt carrier assemblies together from factory Armalite parts.
These are a combination of new and slightly used components that may show slight wear.
Perfect as a spare or use them in a new build.
Will function in an original AR180 if a straight charging handle is used and the dust cover is left open.
The bolt carrier can be machined with a relief cut for the dust cover and one for the charging handle key. You or your machinist will need to perform this if desired. I do not provide this service.
Last two pictures show some examples of some of the wear you may expect to see. No choice on bolt carries. No hand select.
Quantity is very limited and may not ever come back into stock.
