He really shouldn't. One of these days I'll get around to posting some of the research and testing conducted on some of these "wonder" coatings by the US Army and maybe it will show why they are a poor overall choice compared to the basic phosphate coating. How they accelerate wear in the upper reciever, how they promote crack propagation in the high stress parts of the BCG (which the Army figured out in the 1960's and stopped hard chroming BCG's as a result), etc. There is only one coating system currently in testing that has the real promise to be a truly effective replacement to the standard and it isn't commercially available.

Yes on both of these. I have an 80% arms jig. Have already done two others that work really well.

Are you talking about NiB BCGs like Fail Zero?
Also titanium and "ion bonded" ones.
Cryptic Coatings has a "Mystic Black Titanium" BCG for $450.

re: Official AR-15 thread
I THOUGHT about buying another cheap spare AR and maybe a case or two of ammo. But my more sensible side prevailed once I watched the news and heard no one needs those things....

I was tempted, but I'm not panic buying. If you're in the market for a pistol brace however, you may want to jump on it. I could see those going the way of the bumpstock soon.

All of them. Super hard and slick surfaces look nice and clean easy clean but neither is particularly needed or beneficial to an AR-15. You'd want such a surface coating the interior of the gas system to help with erosion, the face of the bolt, and maybe the fire control parts. The standard phosphate coating is like a sponge in that it absorbs a small amount of oil and traps it, providing lubrication but also some cushioning between the rails of the BCG and receiver as the action cycles. It certainly makes it harder to clean but cleaning is part of owning any firearm. Also, the BCG's are full of wear items, they aren't supposed to outlast the receiver. The surface hardness of the phosphate coating and the anodizing used in mil-spec receivers are reasonably close, with the anodizing being higher. You put a NiB coating on there and you have something in the 80's HRC which much harder than the anodizing, something is going to wear no matter how much lubricity the BCG coating has built-in. And since these coating all tout the ability to run without lube that means the receiver is taking up pretty much 100% of the wear. And $450 for a BCG is retarded, even for a competition rifle... There are lots of military applications for these coatings in crew-served weapons, mortars, cannons, etc., but I don't think they are much value in your average combat rifle. Hell, the HC chromium coating used in service rifles today has problems with uneven application, micro-cracking, and excessive hardness depending on who is under the contract making them. Brand new, never fired barrels with surface cracks and this is a very mature technology. My AR's are very plain affairs; I spent extra money on glass, triggers, and some good tools to put them together.

Not to get too political, but Trump noted this morning he is only wanting to push background checks, not seeking an AWB. So that’s a plus.

What more can they really add to background checks?

all solid information however like you said

i would much rather wear out my receiver which costs considerably less than $450 so im okay with it take the beating. also the beating youre talking about is after 1000s of rounds. id like benefit of easy cleaning over worrying about wearing out my upper.

just my two cents

I think they want background checks on all sales. No more private sales if I had to guess

Got my frontier c-5 80% lower in today.

Looks good. Now just need them to get the BCGs in stock.
