I have had experience with both Springfield Armory , Inc. (have two early ones) and Smith Ent. I have a friend who recently bought an LRB.
For what it's worth, my recommendations are:
LRB are hammer forged and therefore have a longer projected life. This extra life comes at a very high price, however. LRB receivers are expensive. The Chinese receivers are also hammer forged but the Chinese mixed some metric in with our inch dimensions. These problems can be fixed by competent machinists (Smith Ent. does these fixes) but again, by the time you are done, you have a significant amount of cash invested.
Evrybody else has cast receivers. Some are better than others. In my estimation, Smith Ent. made the best cast receivers, bar none. Some of the others were terrible. Smith also made some receivers years ago, out of forged bar stock. These are good but hard to find and expensive.
All of the above should be built up with U.S. GI components. As John Holbrook can tell you, the cast bolts & etc. made by Springfield are not even close to GI and most are junk.
Smith Enterprises is in the process of getting back into production with a new receiver. At this time, I don't think anyone knows how it will be manufactured but everyone who follows this M14 thing is waiting very expectantly.
Incidently, If you have to ask about a lug, you don't need one.
