This is an original Remington 03A3 receiver which has been drilled and tapped as an A4 and then modified with an internal receiver block and machined to accept 1922 parts.
The 22 Caliber conversion was completed with an original Springfield 1942 dated barrel and original bolt and internal parts. Barrel date is SA 5-42.
The magazine is a reproduction made by TripleK and the stock is a reproduction from Minelli in walnut.
This rifle is truly one of a kind.
