the rifle was originally designed so as to kill a man at 800 to 1000 yards
let's look at it this way......
some say cutting the barrel will have an averge affect on velocity equal to 25 ft per second per inch.... roughly.
so by cutting back the barrel by 3 1/4 to 3 1/2 inches from 22 to 18.5 we could safely assume a 100 foot per second velocity loss for any given round. reloaders may be able to speed her up a bit to compensate but i can't comment there as reloading is not my expertise.

In my opinion, inside 300 yards , the 18.5 inch barrel can be very accurate and in a battle condition where a man is the target, effectively accurate range would be possibly reduced to 600 yards maybe a bit more.

recoil is straight back next to no muzzle rise,it does have a brake on it too but this is my bear/deer/zombie go too gun now






and shoots the 168gr ballistic tip nice too!

I was so excited last nite that I pulled out my McMillan pistolgrip folding stock for my shorty project last nite that I purchased quite a few years ago for this ... however, I pulled the buttend of the stock out and it spins ... so I turned the shaft and it stops but it's off-centre ... there is a wee hole in the cylinder ... am I suppose to use a punch thru this to keep it from moving when I have it centered? I'm new to this type of stock so I'm confused ... help appreciated????

Before the summer is out I'm going to have to get one of these built. I've got a new-in-wrap TRW USGI bolt sitting in my parts drawer for the last 8-9 years, along with a SA USGI trigger group for a speical M-14 build.

How do these new Polytechs compare to the Marstar Norincos?

IMHO they compare favorably having built USGI clones on both receiver types.

I found the machining in the oprod tab channel to be smoother on the Poly and tighter but slightly rougher on the Norinco. The Norinco has better (less obnoxious) receiver markings than the Poly with its ugly dot-matrix Bell engraving.

I won;t comment on the oprod or bolt since you have both parts in USGI ready to replace them.

The trigger group was better machined in the Polytech, though I know M14 doctor prefers the Norinco hammer and trigger/sear citing them being harder. FWIW, on my Norinco, I gashed the original trigger group (actually I gave it away) and installed a USGI one. On the Poly it was better machined and I kept the housing and replaced only the pins, springs, hammer, trigger and sear with USGI and the mag catch with a Sadlak for Norincos from Fabsports.

The Poly barrels seem to be a bit better IMHO, but that might be because they apear to be newer manufacture and some issues were fixed, such as leaving more metal under the oprod guide and improving the way the crown was cut.

IMHO you NEED to replace the factory flash hider with a cast and machined SAI, USGI, or aftermarket milled hider. Period. In my experience more than 80% are crooked such that the sight dovetail isn't perpendicular to the top dead center spline on the barrel.

One more thing I will say, Every Norinco gas system I have seen was useable as-is. The only "junk" gas system I ever saw was on a Polytech where the gas lock had a big casting inclusion in it (e.g. had to be gashed) and the gas cylinder on the same rifle gauged out of spec with too large a piston bore.

I'm sure others will chime in with varying opinions :)
