Probably
THE BEST receiver currently being made is the LRB, which is a forged unit rather than cast. They are very spendy, running north of $600 for a stripped receiver. They sell complete rifles built to order, or just stripped receivers. They come highly recommended.
Milsurp M14 parts kits are the way to go if you want to build one up on a stripped receiver. They are also quite spendy now, starting at about $700-800 and going up. I saw a VERY NICE one online today for $1100, but all the parts were either NIW or like-new.
I don't know if Springfield is selling stripped receivers now or not. I believe they're dedicating all of their receiver production to rifles now, and selling them like hotcakes!
Springfield rifles tend to be either real good, or not. There doesn't seem to be any in between. The good news is that they
will make it right.
Armscorp recently split the blanket between the two primary owners, and had to stop making receivers for a while. Not sure what their status is right now. One former partner moved and was supposed to start selling his own receivers under a different name. I
think the other partner was set to resume production under the Armscorp name, but I'm not certain.
Entreprise has a spotty reputation and I would avoid their receivers. The Chinese rifles have gained a pretty good reputation when properly set up, but they're a lot like Hillary - people either
love them or they
hate them!
I would suggest joining The Firing Line forum, which is dedicated to the M14 rifle. Lots of very knowledgeable folks there, and they won't steer you wrong.
I was fortunate enough to buy a very lightly used Springfield M1A a few years ago for a very reasonable price, complete with two extra synthetic stocks and handguards, extra sights, and a slew of magazines. A few months later I stumbled across a USGI M14 parts kit (less the barrel and stock) for $400. I happen to have spares of both, so now all I need is another receiver...
