This started as a .303 enfield. Original barrel (included) is shot and keyholes. I bought a 7.62x51 barrel/receiver (great bore) but could never get the original bolt to feel right with it. I believe it just needs the slightly shorter bolt end. It has the 7.62x51 extractor and original extractor included. Includes everything you see. I have not fired it with the new barrel/receiver. I do not believe it is safe to fire as is. Interested in trades.
