RCA said almost the exact same thing, but did you ever call them to ask them to make good on it? Jeez...
Definitely not saying you or your company is like that, and I am pretty sure you are not, given who Azimuth supplies.
My questions: What kind of surface finish is on an Azimuth enhanced BCG? Is the thing slick like a JP, or are there little machine ridges, etc.? Maybe expecting hand-polished slick for the price-point is a bit much, but I'm curious.
Also, other than the obvious dimensional changes, what has been altered from a typical BCG design?
I like what I term "the sand cut".

I can't speak for RCA. But, as stated before, if there is a defect with our gear we will cover it. There is definitely trust on both sides of the coin.
Hand polishing is not done. Adding to what you touched on, we hit a price point thats the same as some standard phosphate BCGs. The machining work is top notch and any machining marks are already at a bare minimum. What we have is a very functional BCG that looks great as well.
Here is some info on BCG. If you would like specs, I can list those too, but the specs are also on our website. We have reviews coming in by Chris Tran, Modern Arms, and hopefully another avenue that we are keeping under wraps for now. In my signature there is also reviews of our standard BCG and our URG. Give them a look as well.
The enhanced bolt carrier is designed to reduce carrier tilt/cant during recoil and increasing reliability by strategically relocating key bearing surfaces. The enhanced carrier has fewer points of contact resulting in less friction area and the slight increase in carrier mass extends dwell time and ensures proper gas pressures for reliable extraction. Carrier bearing surfaces are ground after heat treatment to ensure proper and unaltered tolerances. Every single BCG is also hand debuted then tumbled. The bolt home in the carrier is honed after heat treating as well, to both ensure proper tolerances and smooth movement and to also remove any sharp edges caused by the cam path milling. Every single portion and of the BCG is held beyond Mil-Spec tolerances.
The Bolt is “true” Mil-Spec dimension and external surfaces are CNC ground after heat treat for a precision fit. The bolt bearing surfaces are ground after heat treating to ensure proper and unaltered tolerances.
Here a few pics of the BCG to see the surface finish. The last photo is to show logo placement through the port.

Im normally a NiB guy but that nitride finish does look slick. Spade logo is a nice touch. I do focus mainly on function but I bet this would look great in a burnt bronze upper.

I have a bad case of over cleaning and lubing my BCG's, so on my last build I tried a NIB coated one. While it is easier to clean and needs less lube I am going back to phosphate coated ones. For my preference I like how the phosphate ones hold the lube in place better.

The only "coated" bcg I've had was one of the BCM ionbonded. The next one I buy will be the Fathom Arms for sure, those suckers are beautiful.

I'm in the middle, here. I DO like running things wet, but also realize that the only contact surfaces of a BCG will not retain oil when it's running best.
What I mean is, you have the "skids" and gas-key surfaces. The rest? It's just oil sitting there doing nada except making it easy to wipe the carrier off. Those skids quickly wear down the phosphate layer to bare steel if you shoot even a little bit, and the carrier movement gets slicker and it runs better, in my experience.
So...soaking even a phosphate BCG in oil past the break-in period is kindof pointless, in my opinion, based on "the numbers".
I have shot with other QPQ bcg's, and they flat-out run. Very slick.
My main question is...hardness. How does the extra hardness of the bolt affect the barrel extension? I know a mil-spec BCG has very tightly controlled/spec'ed RC levels on pretty much every surface, and at every depth.

So, after all this... what BCG did you go with?

I picked the UCWRG BCG for this build, though I'll get a Fathom BCG next for our pistol.
