| I just picked up a polytech from a buddy for $250. The rifle has only 20rds thru it the day after he bought it. He had a usgi flash suppresor installed and put it away. I have heard norincos can be good but the polys have headspace trouble. can anyone give me info on these rifles? |
$ 475 here.  You didn't get ripped off and I don't know why someone would say that with out at least saying they were joking. (BAD BAD WATERMAN) You have most likely a fine rifle. My brother has a poly and we've shot it with the original bolt with no problems. If you're real concerned, buy some headspace gauges to make sure it's within spec. God knows you should be able to afford it after you just saved anywhere from $500- $ 2000 to get yourself into this platform. If you're not worried about the headspace. Buy some ammo and shoot it!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Oh yeah, and post pics!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! |

Let's put it this way. It has a forged reciever and a chrome lined barrel, unlike certain commercial models. Check the headspace. Some of the very early ones had a soft bolt, but some will tell you that they all do. Don't listen to them. If it is out of spec, you can have a GI bolt conversion done or order a brand new Norinco bolt (same rifle) from marstar.ca. The rifle, if it is in decent shape, is worth at least $600. You got a steal. The best ammo is 7.62 NATO surplus. That's what it is chambered for. If it passes a .308 headspace test, then commercial .308 is fine. Try to stay as close to 150 to 168 grain bullets as possible. Commercial .308 CAN have a different pressure curve than 7.62 NATO, but a lot of 150gr FMJ is loaded to the same specs or close to it. It's when you start getting into match ammo and really heavy bullets that problems may arise. That is true of all M14 clones. If it will pass a .308 headspace test, Georgia Arms makes a very good 150gr FMJ and have some good deals on it in the "Canned Heat" package. |

Breaks down like this; Bad; May have head space or bolt lug engagement issues. Best to have it checked. May have minor problems with rear sight. May have ugly Chu wood stock. Good; Receiver, barrel, trigger group, op rod and gas system are as good as USGI. Most parts are interchangeable with USGI. To legally have a flash suppressor with a bayonet lug, you will need to have the following domestic manufactured parts, Stock, hand guard, magazine and flash suppressor. Items of interest; The Chinese gas cylinder is made of carbon steel (G.I's are stainless). They are slightly larger I.D.. The Chinese gas piston is slightly larger O.D.. The Chinese gas cylinder lock has metric threads, G.I. will not interchange. The Chinese flash suppressor nut is also metric but the thread pitch is so close to G.I. that a G.I nut will thread on and change the metric pitch to standard. Some claim that the Chinese hammers are soft. I've never seen it, but USGI M1 or M14 hammer, trigger, sear and safety will interchange. Some claim that the Chinese springs are of poor quality. Change the op rod spring if you like. My Chinese trigger group has thousands of rounds without any trouble. The Chinese connector lock pin is a bit shorter than G.I.. If you are using a USGI wood stock, the pin can back out. The stock can be shimmed in the area of the lock pin. USGI synthetics don't have this problem. Use only USGI or Chi Com Mags. Learn to identify them or buy new from 44mag.com. Care and maint. is the same as for USGI M14's. Enjoy your rifle. You got a smoking deal.

You done good  Is it heel stamped or a side stamped IDE? |
btw any chance of seeing a close up of those gas cylinders and how they're unitized?

Will you guy's knock it off allready!! I can't leave the computor for a minute without a thread spouting off about how great chi com rifle's are. Before too long an LRB is gonna be cheaper than a Chi Com. Now repeat after me....CHI COM RIFLE"S ARE JUNK!! Seriouisly SMOKING GOOD DEAL MAN I have over 9000 rounds thru a Norinco 1.5 to 2 moa accuracy with match loads. Do have the headspace checked. Mine is long but not out of spec. That make's it harder on brass. Important if you reload. Maybe at the end of this HP season I'll finally get around to a USGI bolt and new barrel.
