    I think its a little difference when someone is making a comment, as opposed to making it the first post in a thread. No harm done that I can see, comments like that aren't going to turn this into arfcom.
    Stick


    Board policy mandates I state that I shoot for BCM. I have also done work for 200 or so manufacturers within the firearm community. I am prior service, a full time LEO, firearm instructor, armorer, TL, martial arts instructor, and all around good guy.

    I also shoot and write for various publications. Let me know if you know cool secrets or have toys worthy of an article...

    I have never seen a percentage given for the Vltor MUR regarding its increase in stiffness. Deflection tests, such as the one Kino did, would be pretty easy to replicate.

    The other part that really interests me is the tight barrel extension fit. This might end up being a giant win for the average guy on the market. Again, especially at that price.

    I was pleasantly surprised by the price, enough so that I bought my first BCM non-blem stripped upper.

    Any insight on the channel in the upper being for blowback/gasses? If that is what it’s for and it works, I could see myself switching a couple uppers out for these.

    Added gas expansion areas and new channels added around the charging handle opening vent gases away from the end user’s face, *reducing* distractions when employing the weapon system with a can.

    Nice! I usually run the blems, but at this price I'll start grabbing these. Don't think there is enough there for me to switch out existing uppers, but anything new I'll give these a try.

    Those channels/venting sound great on paper, if someone can confirm they actually work I’m jumping on board.

    Likewise. Every little bit helps IME.

    just tossing this out there but these do not work with a geissele rail, the tabs on the lower corners of the rail do not clear the added material on the upper.
