I was told this polytec was upgraded with some usgi parts. So far I am not able to tell what is what.

the trigger group is marked on the upper rtight side upside down with 62001937

the receiver is a side stamped polytec .308 (lol) 16413
under the stock line is the numbers 3418117 also

the bolt has a serial # marked over another serial # with a electro pencil the top appears to be 33495
under that is hard to tell but looks like 383?0
these are both on the underside of the bolt.

I looked as hard as I could on the bolt and could not find anything

the OP rod lightly says in electropencil

33495
and also 0E5380 even lighter

I also could not find anything on the gas piston or any other parts.

any help is greatly appreciated.

It is Just like Chevy,Ford, Dodge. Some people love them Some Do Not.Some Run Good, Some Run Better than others and Some are just a Lemon.
My best friend has a PolyTech and he loves it and it runs like a Champ
The only thing I would do is check the Head Space and replace the bolt if needed
Perhaps as $ is allowed slowly replace with USGI parts
