Re; Polytech M14S:
I own one of these rifles. It had been significantly updated when I got it, it has a chromed bore (standard), USGI flash hider (over bored), match iron sights, reworked trigger, springfield scope base w/burris 3X12 power scope. Ifound the headspace to be excessive, (bolt closed on field reject guage) which necessitated replacement of the bolt with a USGI bolt. I then replaced the chicom wood stock w/a polymer stock. Total tab about 9 bills.
Looks GREAT!, functions perfectly, essentially it is a match rifle, maybe not up to max standards but very accurate. Hope this is of some help to you.
