Some of the posts in this thread are typical LOL exploding bolts are not very common
10 years of constant new content in the main battle rifle forum is a testament in itself to the popularity of the chinese M14/M305. The rifle has a cult like following and at the same time has brought out the tinkerer in many a gun owner. No, the chinese M14 is not perfect and like has been said, they do produce their lemons so buy from a dealer with an exchange policy/warranty.
BUT if you like to tinker and play with your tools... The chinese M14 is certainly a fun rifle to own. That and there is a fantastic community here to be part of and make new friends. The thing that makes them popular is not accuracy out of the box, it's not the finishing on the metal , it's not the sloppy parts fitment... It's just that they are a real fun rifle to tinker with and a real fun time to shoot.
That's my thoughts anyways.
My sentiments exactly. Ya saved me a pile of typing. The M14 community is the envy of the CGN community. I often get PM's from people asking about milsurp or hunting rifle schtuff because they feel invited to share and that's great.
Just a few observations:
Many people start their tinkering / tweaking /modifying on the M14 before expanding their comfort level into other platforms (ex. Ruger 10/22, AR15's, Rem 870, Rem 700, Savage 10/111, Tikka T3, Mossy shotty
Many people have started reloading (coming from a factory ammo background) because the M14 platform necessitated such a move. Welcome to the hobby within a hobby.
Some M14's allow themselves easy and drop in mods from USGI or M1A spec'ed parts, some don't which leads to the conclusion that some Norc/Poly M14's are 'more in-spec' than others.
Goofy QC makes the swap ability less predictable and mysterious, hit and miss is what comes to mind. Sometimes more hit and sometimes more miss depending on the rifle / shorty you end up with.
Some Norc rifles shot really well when tweaked and then shot better with swapped parts (from USGI or M1A rifles), some of them shot like KRAP and my fix was to "part" out the entire package and recover your money. With the Norc/Poly rifles, it's like a "box of chocolates."
I've met soooo many people doing their own parts swapping in and out, they have become experts and started helping people all over their communities. Ah... that's part of my vision. I ain't gonna live forever.

Don't plan to either!
I've noticed that whenever M14 Norc/Poly parts are posted for sale on the EE Forums, they sell! Not always quickly, but they sell....
Anyways, I've got a moose hunt coming up in a few days and I better screw off that .22-250 coyote sporter barrel and replace it with a .308 barrel on my hunting M700. My guardian angel gunsmith helped me get set up with a 700 that now has THREE barrels (.22-250 for coyotes, .308 for large game, and .223 for gophers and earth pigs). Yes, I have a .308 bolt face bolt AND a .223 bolt face bolt. So depending on the season, my M700 can serve triple duty. That's what happens when you can only have one hunting rifle, but at least I've got a Leupy Mark4 duplex on a set of ARMS22 throw rings and that helps the caliber/season/game swapping.
Cheers and keep on helping them noobs.
