Any potential customers on someone that can make a superb eighty% Colt marked lower? I'm beginning my journey building a circa-1968 M16A1 and am striving to locate a decreased. I'm serious about attempting to source a reduce with all the proper Colt markings.

It is simply the character of Market/Customized goods, nevertheless this is a bit more time sensitive. There's multiple issue Functioning in opposition to me, so If you prefer just one vs waiting and acquiring one particular off GB a long time in the future for more, just get it done.
