C&R MG42 German Machine Gun

MFG CRA in 7.62mm x 51 and 8mm kit 21-3/4" barrel with a very good bright bore.
Referred to by the Allied forces as "Hitler's Zipper" or "Hitler's Buzz Saw", capable of firing 1200 rounds per minute. The MG-42 replaced the MG-34, being easier and quicker to manufacture.
Built largely from stampings and with quick barrel change to accommodate rapid rate of fire. Designed by Mauserwerke in collaboration with Grossfuss of Dobeln. The recoiling parts were lightened by the designer to allow for more rapid rate of fire.
The guns method of operation is often described as short recoil, gas assisted and roller locked which became the standard design feature in HK MG. The top cover mechanism was later copied in the US M60 MG.
