    Coatings on the carrier aren't all that important, at least in my opinion. But if you do decide to look at other options, please give DLC a gander.

    I must not have ever noticed that you use Wiley Arms as your machine shop. I don't think I've ever noticed them before. Just started following them on IG and FB.

    BCG looks great. Interested on what the "S" stands for and how different the bolt itself will be.

    It will be staked

    Wiley Arms used to be (and still is) an OEM user, they build precision rigs. I'd like to use their lower as a template, alas they're very busy, we'll work on the upper first, as it has fewer changes.

    Make one of the bolt options a 6.5 Grendel and you can have my sister's firstborn son.

    We are going to need to see a pic of her before that could go any further.

    @ Duffy. Are the recesses on the bolt head so the swaged material from the carrier key actually bite/bind into something?

    Lots of info on the OCKS on m4carbine.net http://www.m4carbine.net/showthread....ier-key-screws

    OCKS, provided they're properly staked, add another layer of assurance the screws will not back out. It's a rather smart and yet simple implementation, wish I had thought of it first

    We're couple of weeks before product launch, so now we can show some pics



    This is an SBCG prototype. The laser engraving took up a lot more time than I cared to spend, mostly to make it small, which is a problem when it's TOO small lol. I want the wing span of the Cygnus to be no wider than 0.25, the engraver talked me out of it so it's now slightly bigger, but still on the inconspicuous side.

    The prototype doesn't have the gas key. As stated previously, the secure staking aspect is the heart of the SBCG. SBCGs will be sent to Sionics to have OCKS installed and staked, also using Ned's industrial strength staking machine.

    The serrations you see (or might have missed) are the "slick side" portion, for folks with uppers sans a forward assist. The area forward of the two gas vents can be used to push the carrier forward, the serrations simply make doing so easier than a finger on a normally smooth surface. Throughout the thread, I've downplayed this part of the SBCG, because it is a minor change/improvement, we've seen such implementation on some G3 carriers, and the half moon shape cutout on the UMP bolt carrier serves the same purpose.

    Despite the assertion that the area is meant to be used as a forward assist, I disagree, I'll need to take this up with Chris Bartocci to get the real answer. It's concave to accommodate the ejection port's spring loaded ball bearing "bump", I don't believe it was designed for a finger to push on it. Nevertheless, it does have the shape to be used in that fashion, so we added serrations to make pushing on it easier.

    I like the serrations for your thumb/finger, noticed them and knew what they were for immediately.

    SBCG marks the last of our 2017 product offering. This year saw the introduction of 7.62mm spec ABC/R v2, EMR-A, 6315, and just yesterday, URF. SBCG has been significantly delayed, I would have liked to have it available for purchase at the same time as URF.

    For 2018, we may see an URF2 and a castle nut done Forward Controls way, simple one piece ring as the original, but can be more securely staked than the TDP spec unit.
