Well. I tried out both M1 Garand and M16 slings today at a local gun show. They are close, but they bind. One seller told me that they were made from spring steel (can't be easily modified) and there are more bends in the original M-10 style hanger piece.
Looking for a Mac 10 front strap with the metal clip (Powder Springs?) as my M11-A1 does not have the larger slot that would accept a Cobray type strap with a button. Reproduction is fine as its for a shooter and I can't find one anywhere. I believe that the original ones are olive drab in color.
Have Paypal or could mail a certified check or money order.
Thank you,
