This item was cast from an actual M6 bayonet, used on the M-14. It has all of its maker's marks in place, U.S M6 and the company that made it AERIAL (an uncommon maker I am told). The bayonet was cast in a silicone mold so it holds all of the detail of the original.It is a good alternative to carrying your expensive original into the field, or an excellent display piece. It is cast in a black resin. Item will be packed very securely and shipped via US priority mail for $6.00. (Other shipping methods available if you prefer. International shipping will cost more. Email to let me know).
