Springfield 1903 peterson device (clip not included)

This is fully functional 30-06 Springfield 1903 Mark I

Pedersen's concept was to provide rifle-equipped infantry with a weapon that produced a high volume of semi-automatic fire in the assault and retained the capability for the long range firepower of a standard infantry rifle. The M1903 Mark I rifle had an oval ejection port in the left side of the receiver, special stock modified to accommodate the ejection port, special sear/trigger and modified magazine cut-off. Prior to installation of the Pedersen Device, the Mark I rifle fired the standard .30-06 cartridge and functioned exactly like a standard M1903 rifle. On removal of the bolt and insertion of the Pedersen Device and 40-round magazine, the Mark I rifle functioned as a semi-automatic rifle firing the low velocity .30 caliber Pedersen cartridge. The Ordnance Department adopted the Pedersen Device in March 1918 and for security purposes designated it.
