    The various buffers are due to the differences in barrel lengths, operating systems and port sizes.

    If you use Colt as the baseline and look at what they sell and what buffers they use then you have an idea.

    The reason there are various springs just like everything else is because of a persons desire to tinker. Admittedly some springs do work very well and have a purpose.

Why constantly tweak your buffer system for different barrel lengths, gas port sizes and running suppressed or unsuppressed?

    The point I was trying to make is why constantly tweak your buffer system for every upper you own when you can simply use an A5 as a universal system. No need to worry about matching your different buffer systems to your uppers.

    Just like the rifle buffer.

    There is really only one flavor, and it just works.

    The A5 actually improves on the rifle buffer with the addition of a biasing spring.

    Markm has a little pile of these somewhere, if anyone wants one :-)

    A biasing spring can easily be added to the rifle buffer to achieve the same effect.


    Looking back at history, all these different CAR weight buffers just have users and Mfgs chasing their collective tails on tuning and gas port size selection.

    I firmly believe that a full weight buffer is extremely beneficial / necessary for proper operation of the AR across a wide variety of conditions, especially as barrel lengths and gas system lengths get shorter.

    The standard weight (original design) delays opening and extraction enough to make cycling very consistent.

    These lighter weight buffers make actions open faster and shortcut the normal extraction process, leading to trouble.

    Time to unlock is affected by:
    BCG mass
    Gas system length
    Gas port size
    Cam track length

    So, to delay unlocking the most, you want the highest mass, longest gas system, smallest gas port and longest cam track you can get that will still cycle the action.

    Well DSG just sent me my A5 RE last week, but the buffers & springs are still on backorder (since December 2012 for my order). I just hope Vltor gets them out in the next few weeks.

    Another variable to consider is the application of the AR. I happened upon similar discussion among the 3-Gun crowd about the relative merits of different buffers. Some interesting, albeit unscientific, observations there

    P.S. glocktogo rogtac has the A5 buffer and spring in stock.

    So for a 16" Noveske middy which A5 buffer should I run??? A5 H2 (5.3oz) or heavier?

    I think I heard somewhere that all Noveske uppers work with the A5H2.

    Thanks,
    Just ordered my A5 buffer/spring kit from ROG Tac who has them along with the 7 position A5 tubes in-stock.

    Midway USA & Bravo Co. also have the 7 position tubes in-stock.

    I use an a5 with my noveske n4 16 inch middy barrelled home build. Shoots like a dream and has been 100% reliable with everything I put in it.

    I contacted Noveske about that a couple of years ago and was assured by Todd K. that all Noveske N4s are designed to work with rifle buffers. Since then, almost 10,000 rounds, I have found that to be completely true. The A5 on my Light Recce midlength has worked perfectly.
