    Who are "most people"? 10.5" guns are notoriously finicky and there is no standard buffer weight which will make them run as gas port dimensions vary widely.

    I repeat my earlier assertion that no other buffer system runs as smoothly, or as well in so many different uppers, as the A5 with a std A5H2 buffer.

    The fact is, there are dozens of posts over many threads here on M4C where the A5 system has taken previously unreliable setups and made them function reliably with a wide variety of ammo.

    Most any company can invest relatively little capital money to study the versatility of the carbine type action system to the rifle type/ A5 action system. I seriously doubt that any that do so would come to the conclusion that the carbine action system could be utilized in an equal role for as wide of a range of the rifle type/ A5 system. The curve of operation supports the higher mass with less spring over carbine type action.

    Exactly.

    And we still have yet to see a combination where a carbine setup would work and an A5 would not.
    Why do the loudest do the least?

    Another bit of data.

    Colt 6920 equipped with Vltor A5H3, green Sprinco and SIONICS NP3 carrier group. Weather was about 55 degrees. Ammo used was Lake City M855 and Federal M193. 100% function with about 90 rounds fired.

    Does the NP3 contribute to smoother cycling? Is it similar to Cerakote MicroSlick?

    I wouldn't expect different results than this. If lower powered ammo is used, then there could be an issue. It would be very hard to argue that that the standard action system with the provided H1 carbine buffer is superior in function and reliability/durability compared to the A5H2 action system with a Colt rifle spring in a Colt 6920. It would cycle less "snappy" for sure, but overall an improvement in operation.

    You're saying A5>stock set up in both smoothness and reliability, right?

    I have no idea what Cerakote Microslick is.

    No, reliability would tend to be a yes.
    Smoothness isn't something that could be said across the board as universal. There are circumstances that differ as this is something that is not directly measured for the most part. There are higher and lower mass reciprocating mass systems, multiple action springs, and other variables that come into play.
    The carbine action system will cycle at a higher rate than the rifle type action system in general.

    I would be happy to send you my Microslick BCM Bolt Carrier Group for long enough for you to compare to your NP3 coated one, if you are curious. I am personally curious about the NP3 BCG. If I can finish saving in time, I'll end up with an NP3 BCG when I purchase my Sionics upper.

    In relation to this thread, I'm pretty curious to see what it's going to be like to take my over-gassed M&P15, my stock Colt 6920, and a mid-length Sionics Upper on a Sionics A5 Lower and run them all side by side. I'm hoping to feel a difference between the three. If it's a notable difference, I'll out fit my other two ARs with A5 stocks.
