in 1932, a much shorter version of the m1918 bar designed for 'bush warfare' was made by usmc major h.l. smith. captain merritt a. edson wrote a report on this rifle. edson was the ordnance officer at the quartermaster's depot in philadelphia, pennsylvania. the barrel was made nine inches shorter (229 mm), and there were some other changes as well. the changed bar weighed 13 lb. 12 oz. and was only long. this version was more accurate than the bar when firing automatically and while lying down, it was less accurate when fired from the shoulder. it was also very loud. though the report written by edson said that six of the 'jungle' bars should be built for testing, no more work was done on the project.
