AR 15-Uppers not like M4

[lopezni]

Since I can get lower's so cheap and so many people I know shoot them at club match's, I am debating on building an AR. However I cannot find a complete upper I like. I don't care if it is an A2, flattop, whatever. I do want a 20" barrel, no flash suppressor, and no chrome lining. Ever seen one like that?

Just out of curiosity why wouldnt you want chrome lining?

"...no flash suppressor..." Most barrels come with the threads, but contact this guy. He makes a thread protector too.

You do know that building one will cost a great deal more than buying one.

if you build piece-by-piece, sure.

If you buy a competitively-priced complete lower, complete upper that is near your liking, and customize it a bit, you can save a good deal of money.

Most varmint uppers come like you want. My RRA Predator Pursuit has a 20" SS National Match barrel 1:8 twist, no threads.

because they put chrome in the barrel just because of the people who load up a 30rd mad and go bam-bam-bam, unloading the mag in 30 seconds. If the barrels weren't chrome lined they wouldn't last very long now would they? The chrome does not wear evenly and accuracy deteriorates significantly over time.

I'm not sure that in your standard-quality barrel you would notice a significant difference between CL vs non-CL in the accuracy department. Now, you get into match barrels, yes, there is a difference (as evidenced by there being few match CL barrels). But for your standard production barrel, I doubt it makes much difference. I have a rack-grade A1 barrel and a commercial production M4 barrel that is non CL, and they shoot about the same.

It's not so much chrome deteriorating, it's about the process. Chrome lining the barrel means button rifling it oversized, then chroming it back to the required dimension. The plating process, however painstakingly accomplished, cannot hold bore dimensions to ten thousandths of an inch that is required of a precision rifle. It does ok in military use as that is 2MOA. Precision shooters are looking for 1/4 MOA barrels, and pay dearly to get them.

Precision barrels are typically stainless, rifled by the cut thread method, and can hold an internal variation of less than .001". Chrome won't, hence the lack of chromed precision barrels.

Chrome does a good job of blast resistance with full auto shooting, most recreational owners don't stress the barrel enough to need it unless mag dumping a lot of cash for the fun of it. Nitriding barrels is becoming an alternative, partly due to the cost of chroming and the associated OSHA regulations, partly because it effectively protects the barrel as well, and offers other qualities desired.

All the better makers offer varmint uppers, keep looking and hold on to your wallet, they get attractive.

I built one for a friend with a Stag lower and it is rock solid

nice gun

well thanks for the info. I can get a DPMS lower and an AR-Stoner parts kit for $180. A friend is going to give me an A2 buttstock and a grip. I'm in no hurry so I'll probably build the upper too. I really want a quality barrel since it will only be used in club matches.

A second for WOA, get the pinned rear sight for another $55. Compass Lake also offers a great service upper with the same features but a few more $$.

if you're looking for superb accuracy, i believe chrome lined barrels are not the answer..
