    Google works from your computer just as well as mine.

    Being that the weight, and variance of, is a part of the design, I don't see how it's any different than an other ill suited or mismatched buffer. Nor do I see any demonstrated benefit to having the buffer weight powdered.

    I am also of the view that probably the biggest significant factor to a weapons perceived recoil is the weapons overall weight and of course the ammunition used. Not the buffer.

    I thought I read a while back someone was trying to formulate a way to quantify and measure recoil and it's reduction with certian add on parts. While this hasn't materialized yet, it will be a good read when it does.

    Not a cool kid argument, just a product I don't see benefit in.

    Run what parts you want.

    ST/AIM include those buffers with most if not all of the uppers they sell. If they are causing problems in a given application I imagine any same weight buffer would in the same gun. All I ever hear about them is that they aren't any better than a rattley one, no worse. Mine works, it was all but free.

    no setup is the wrong setup if you understand the forces and issues involved and take steps to ensure reliability. but how many people do you think are out there running a 14.5 middy with some combination of spring and buffer that they saw kewl pics of on the internet, and are totally bewildered when their gun won't cycle low power ammo?
    Point taken.

    All I did was to run a test using a modded A5 system with a particular low powered ammo that has proven reliable and accurate. I modified the A5 buffer because I understood the forces and issues involved, ensuring reliability, and to my satisfaction the combination worked.

    Will I run the super light H0 buffer with any other ammo, no; I don't want a battered AR.
    Will I buy more of ASYM training ammo for the next class, yes, now that I can run it on both my middies & my carbine length SBR's.

    I think there's quite a misunderstanding of the A5 here. Does a carbine buffer work with every set or does an H3? Nope, and neither does an A5, but it does a heck of a lot better job, barring the occasional 14.5" middy.

    For a while, I was running the A5 on my SR15's. I still do at times, but the standard factory set up works fine. I also run it on my other guns and it makes the 10.5" feel like my SR15, but even better, it allows it to eat anything I run through it, and very well at that.

    Try it on a 14.5" carbine or especially a 16" with a carbine gas system, you'll see a difference in all but a few occasions. The softer recoil of the A5 on many systems, not all, is a positive side effect allowing quicker shot recovery. If you are buying the A5 for your middy 14.5" or similar, to make your gun softer shooting, you're not buying it for the right reasons.

    If you're buying it because it may make your overgassed, SBR'd or finicky rifle more reliable, then you're headed in the right direction. Another reason one should consider the A5 is if they have one or two lowers (maybe SBR'd?) and a handful of uppers, especially if they range from a 10.5" to a 16" or 18" middy or rifle system and often use those uppers on the same lower or two.

    I found that the other weekend when hunting that I used my SR15 on my SBR'd Noveske lower as well as my mk18 (block 2, I guess) upper and just left the KAC lower sit in the house. Both performed equally well for three days suppressed, both felt almost exactly the same and both ran everything from Monarch steel cased to Nosler 77 grain and TAP 75 grain.

    I posted this a while back and feel more sure that it's true now -- There's obviously a threshold here with the AR and a particular ammo that once it gets to a certain point, it can't get any softer shooting without sacrificing reliability. Believe it or not, sometimes a carbine or H buffer is all we really need for a particular combination of gas system, barrel length and ammo, not to mention the gas port size from that particular manufacturer.

    Rifles I have personally seen work with the A5 with no modifications. Ammo was often xm193 and Winchester 55grain .223, but some (the ones that belonged to me) have had a mix of basically everything.

    LMT 10.5" mk18

    Noveske 10.5" mk18

    KAC SR15 16" (both new and old gas port sizing)

    Noveske 14.5" carbine gas system

    BCM 18" mk12 mod 1 clone

    LWRC PSD 8" (could have used a heavier buffer)

    PWS Diablo upper in both 5.56 and 7.62x39

    Now, I have not seen it fail in any upper I've tried, but there have been times where a different weight would be preferred. Maybe replace one tungsten with steel on the SR15, especially the older, smaller gas port, and maybe replace one stainless with a tungsten for the 8" PSD.

    I don't have enough experience with the 14.5" middy to say, but I do know BCM, for example, uses smaller gas ports than Noveske, also for example.

    After posting everything showed up... this forum is drunk!

    I think I basically get the idea now.

    I'm kinda new to posting here. Anyone know why i'm getting email updates but when i visit the thread the posts are not there and even on the main forum it shows the person who posted last but when I read the thread its not there.

    That's not the first time I've heard Noveske likes healthy gas ports.

    Is this true? Noveske 14.5" mids have bigger holes than BCM?

    It seems to me that a good solution would be a highly tuneable version of the switchblock... maybe?.... i dunno...

    I have a 16" carbine gassed DD. Do you guys who have had time on both middies and A5's think i would benefit more from an A5 or a new mid gas barrel?

    If i went with the A5 it would kill 2 birds because i'm already set on purchasing the Emod stock. The DD carbine CHF barrel is basically brand new.

    Some say that they cant feel much difference at all between mid and car length gas systems but ive also heard the same regarding the A5. So, would i notice more of a felt recoil reduction with the A5 system or installing a middy barrel??? What do you think

    Thanks

    For reference, i've never fired an AR with either one of these upgrades/options.

    After running the A5 system on everything from an 18" SPR, 16" mid, 16" car, and 14.5 mid, I highly recommend it. I am slowly converting all my lowers to the A5 buffer (I have 3 so far). I really appreciate the smoother shooting characteristics, and have found that it works better than a battlecomp, as far as calming down a carbine gas gun.

    Now an A5 and a battlecomp- thats the best of everything. But between the two, I would get the A5 first.

    In your case, keep the barrel you've got and put an A5 behind it. You will probably be able to run the A5-3, which will further help your carbine gas system.

    So you haven't had any problems with the A5 on a 14.5 mid?
    What buffer are you using and what brand barrel?
