Found a archived thread by RRiggs dated 8/8/2013 and pictured along with a in the wrap 1969 XM3 bipod case he had a bipod with clips on both sides in a clear wrapper, I'm inquiring re any markings on the bipod or the wrapper. Going thru my equipment cabinet today I found hidden away a knurled handle three piece gray parkerized steel rod with short tip M16 cleaning rod in polycraft envelope dated 1964, did some checking and I'm certain it's a M11 from photos and description/specs I researched. I also have the next in the series M11E1 cleaning rod. Printed in black on the USGI tan polycraft package, 1005-070-7812 Rod 1 Each DA-11-199-AMC-518(Y) A - 8/64. The tan polycraft package is marked 7/64 SEAL BAG 2131 with a 1/2" arrow. Package is 13 3/4" long and 2 3/4" wide, the shape of the polycraft package with rod parts inserted doesn't allow space for anything else. For 50 years old the package and rod are in very decent shape.
