    H6 Buffer

    http://damageindustriesllc.com/store...product_id=394

    Does anyone use this? Is it still in military service?

    I’m curious what range of gas ports/barrel length/ammunition type run well in this. It seems almost like a simpler approach to the idea behind the A5H2 and system,

    The A5 system is more than just a heavier buffer, it’s also a rifle length spring in a 7 position buffer that’s .75” longer

    I've had one for about 5 years and have used it with a couple of 16" midlength uppers. It works fine. I haven't tried it with SBR lengths or anything overgassed so it's not a broad test. It's probably a fraction better than an H2, but not very different in my experience.

    If you're building or want the ultimate, I think the VLTOR A5 system is better overall. If you want to stick with a carbine length buffer and tube, this is probably very slightly better than an H2 or H3 if your rifle is on the edge of overgassed, but I don't find any real difference vs. an H2 in my use.

    This is a good summary.

    The H6 is not bad like some other solutions, but it's no match for the A5 or rifle systems.

    Receiver Extension is the correct terminology.

    Same approximate weight as H3, so probably best used with a suppressor or 5.56 pressure ammo.

    Thanks for the info.

    All the rifles I have built have started with or finally been converted to the A5 system (and one rifle). But I do have Colt and BCM factory lowers that I really don’t want to change anything on other than going to an H2...or H6 buffer. Just as an explanation, which I should have started with.

    An H3 buffer is a standardized part and is 5.4oz. For a stronger spring you can go to SpringCo and get a blue, red, or even orange.

    Hey look, a thread from 5 1/2 years ago that reaches much the same conclusions!

    https://www.m4carbine.net/showthread...7657-H6-Buffer

    And yeah, I bought my H6 around or shortly after that discussion. Like many I like to try stuff out for myself.

    My experience is that an H3 and stiff spring will make most rifles choke and FTF. I've only had good luck with an H3 on an Adams Arms piston setup, which was outrageously overpowered and is no longer in my collection. If your rifle can run with an H3 and Springco red installed, even on the hottest legit military ammo, you should replace the barrel or install an adjustable gas block. Maybe an exception if all your shooting is at air temperatures of 100 and higher.

    I looked up the prior thread to confirm the weight, which is 5.15oz in that thread and reported elsewhere as 5oz. Either way, slightly lighter than an H3. I would take an H6 before an H3, and in fact my H3 is currently not in use, but kept on hand in case I encounter something that overgassed. OP, I think an H2 and a quality spring (not necessarily Springco, although their blue is fine) is the most that I would spend money on for your stated use.
