I'd agree with him. The top tier ARs I've used ran fine given proper cleaning, lube, and decent mags. The million dollar questionis how they do with foriegn obstructions like sand. I couldn't tell you.

So what entry level or "bargain brand" rifle did you do this with for comparison?

Looks to me like only half the experiment was done. I'm gonna have to go with Nipprdog on this one, unless there was part of the article I missed.

Very good read on gas impingement though. I might look into changing some springs now.

The article isn't about bashing the lower AR's. But more about showing what a good AR is capable of. No oil is pure abuse. I'd never try that.

Not saying that. I just think you can't really say, much less write an article about, what a "good AR" is capable of if there's no "lower tier" AR to stop running first. Basically, how do you know that my $640 Del-ton Frankengun won't outshoot your $morethanmine.99 BCM?

Not jumping your case, I just think you have a little more research to do. And being a budget gun buyer by principle, I'd eagerly await the results!

FWIW, I run my rifle a little on the dry side with nary a problem! :neener:

You wouldn't try it unless the rifle was designed to run that way. I agree that abusing a regular rifle by running it without oil is just stupid.

NEXT GENERATION ARMS MP168 SPC 5.56mm

A Special Purpose Carbine that runs 100% reliable without any lubrication!

There’s an old saying the there is nothing new under the sun and in the world of firearms, that is generally true, especially with AR-type rifles and carbines now that everyone with a machine shop seems to be producing. But occasionally something comes along that is different from the rest of the pack. Next Generation Arms has entered the burgeoning market with an AR-type rifle that is unique in several ways. There are three versions of Next Generation’s rifles and carbines: the JC 382 Patrol; the JC 382 Tactical and the subject of this evaluation, the MP168 SPC (Special Purpose Carbine).

Gun Details
Externally, the most obvious difference between the MP168 and others is the ARMS (Atlantic Research Marketing Systems) upper receiver that features an uninterrupted full-length MIL-STD-1913 top rail and shorter at the handguard sides and bottom, plus free-floating the barrel, enabling mounting accessories without affecting the rifle’s zero. The MP168’s 14.5-inch Noveske barrel, featuring a 1-in-7-inch twist, is ceramic plated along its entire length for rigidity and heat dissipation. The irremovable proprietary ceramic plating fully permeates the barrel and is so effective at dissipating heat that an operator could fire an entire magazine on full-auto and just a few minutes after shooting, the rifle is cool enough to put away.

Meanwhile, the ceramic means the weapon is impervious to any corrosion-—even salt water. While several companies offer excellent aftermarket ceramic coatings that can be applied at home to any firearm, Next Generation Arms uses a process pioneered for the aerospace industry. Because the Next Generation Arms process actually penetrates the substrate of the material it is applied to, it is not possible to remove it without actually removing the metal itself.

The test rifle also came equipped with a Primary Weapons Systems FSC556 flash suppressor/compensator, one of the most effective devices available. Fit and finish of the MP168 are excellent. We were particularly impressed with the mating of the upper and lower receivers, which exhibited absolutely no “play” whatsoever. Next Generation’s MP168 is one of the best-assembled AR-type rifles we have ever seen, as each rifle is hand-fitted before it leaves the factory. But quality is only the beginning, unlike most other ARs, the MP168 runs without lubrication of any kind.

I agree that the FAL is an incredible weapon. I coated mine in the same stuff and it runs beautifully. I don't think I will every put 10,000 rounds through my gun with the price of ammo/reloading components these days but it's nice to know I can.
