I believe you will find the Poly Tech to be an excellent rifle. Provided it was treated well. I bought one in 1992, and I have had zero problems through it. I am in the process of tinkering with it though, to improve accuracy. The rifle, as it is made, is basically rack grade and should shoot 2 to 3 inch groups at 100 yards. With a shim kit and some trigger work it is easy to cut that in half. Most of the rifle will accept milspec parts, with the exception of: barrel gas tube threading, gas tube lock ring, and flash suppressor nut threading, bolt. Having said that, the receiver will accept USGI barrels and after market barrels (go figure). I don’t want to play the game of which rifle is better or worse, but the Poly Tech is a good serviceable rifle, and should give you little trouble. Report ably, the weak link in the rifle is the bolt. It has been said they are soft, and the firing pins may not be mil-spec. I am going to have my bolt changed out, as soon as it gives me the first sign of trouble (1k rounds through the weapon so far). In addition the wood stock that comes with the rifle is dimensionally incorrect. Do yourself a favor and pick up a used USGI fiberglass stock for about $20. It’s a simple, cheap, drop in upgrade, that will also aide in accuracy. In regard to scope mounts; I use an ARMS 18, that fits like a glove (perfectly). There are other mounts out there that should work fine; I have had good luck with the ARMS though. Just don’t buy the Springfield Arms mounts (for a Poly). They are not made to mil-spec (at least I don’t believe they are), and the one I had (Gen I) did not index properly to my receiver- had to pitch it. Oh the other thing you will hear is the finish stinks. It’s basically just a green/gray parkerized finish. Reminds me of the Remington Rand I carried in the service. It works- shoot it, and enjoy.
