I've noted that some small SAI M1A parts, being sold by Brownell's, are marked Made in Czech and Made in the USA. In the past it was thought that most of the SAI parts made for the M1A came out of China through Wayne Machine Co. I was told awhile back that M1A forged bolts were also made in Czechoslovakia. If this is all true it is a big improvement although there have been reports of bolt failures. Of course, GI bolts have failed too. What is not evident is whether the parts are Mil Spec.
