do you have any real knowledge and experience with the M14 platform ? if not , pipe down and let the rest of us who do , offer our thoughts.
we are seeing far too many broken bolts lately, a problem rarely seen when i had the shop open servicing these rifles. As someone who has handled 100's of the chinese M14S/M305 rifles, in nearly all configurations..... I can say that this brittle bolt situation is a new issue. The fact that since joining here in 2006, pretty much 80 to 90% of my posted content has been pertaining to this platform, I can say without a doubt, that these suspect bolts are either the rejects from previous years manufacture...... or somewhere in china , they are manufacturing new bolts. Who knows what goes on in China, maybe they never did stop making M14S/M305 parts.... maybe they just recently , in past few years, brought machinery out of storage and started up again.
Someone out there knows, but I don't. What I do know is that a fella that has wayyyyy more experienced in these things and has had business dealings with norinco/polytech for decades dropped some info on me back in 2010. I was told that the china was at the bottom of the barrel when it came to the parts manufactured for these rifles, including receivers, in the 90's, that brought us all those excellent rifles 98 to 09.
The proof is in the pudding..... something changed after 2009 ..... right around the time we started seeing other companies invest in the chinese firearms and doing thier own importing. I have not been comfortable buying a chinese m14 type rifle of any year after 2009... and I have never broken a chinese M14 bolt. I've also put 1000's of rounds down range in 100's of chinese m14 type rifles from stock to highly modified..... and never broken a bolt.
I'm not an expert...... I just play one on CGN
