The 722 was the rifle which eventually evolved into the remington 700 short action. It was chambered in several calibers (.222, 300 Sav, 257 Rob, etc.) and carried (originally) a trigger of nearly the same design as the current M700, with the same flaws. The largest difference between the M700 and the 722 was styling.. The bottom metal on a 722 is stamped sheet steel, while the M700 sports alloy castings and hinged floorplates etc. Also the stock itself was restyled and the finish changed. The 2 stage trigger I find intriguing..remington never made such a beast at least to my knowledge. There were set trigger mechanisms made and I suppose someone could have made a 2 stage trigger for some reason.. But that is a mistery.. Perhaps a really light trigger with overmuch sear engagement to help with safety issues?? Both rifles are made from tubular steel and with a recoil lug created by sandwiching a steel washer between the barrel and receiver.. Both the M700 and the 722 were accurate and well built rifles with the quality of manufacture going to the 722 and the earliest M700's.
