    ST-T2 Tungsten buffer. No problems at all with a verity of Russian steel cased ammo and some Israeli hot brass.

    Muzzle punch optional.

    I have a 16" middy with an H-Buffer and BCM spring.

    I have not used a Sprinco Blue + H2. Anyone running this setup? Any issues? I'm about due for a new action spring, and may upgrade to an H2 and see how it works.

    I have been running the H2/blue springco for thousands of rounds using XM855/193 from federal and IMI. No short stroking or last round lock back issues at all.

    Eta - 16" bcm middy.

Used a CMT BCG initially (with the H buffer) but have the brand new LMT Enhanced wrapped up in an oily Ziplock and would like to use it.

    I'm gonna play with it this weekend and see......
    Try an H buffer as well. If it doesn't lock back with the H then try the C buffer.

    Roger that.

    I'll replace my H with an H2 and Springco Blue, and see how she runs.

    Thanks for the info.

    No problem. I've never tried any weak 223 so I can't comment on how that will work, FYI.

    I think what buffer/spring set up you use is going to depend on what you use your rifle for.

    If the rifle is only going to be used at the range and carbine classes then go with a VLTOR A5 or an H2 with a Blue Sprinco Spring.

    If you're a SHTF type person and the rifle is going to be the one you grab for SHTF then I would use an H buffer with either the stock spring or a Blue Sprinco Spring. In a SHTF situation, you're going to want the rifle capable of cycling the weakest ammo reliably. There's a good chance you may not be able to load up every magazine with XM193/855.

    Thanks for the heads-up.

    I have, honestly, used nothing but brass 5.56 as long as I've been shooting these things.

    I'm going to keep the H buffer in my parts drawer, along with some old CAR buffers that have been yanked out and thrown in there, should the need ever arise.

    I too run a 16" bcm middy with a BCM spring and an H buffer with no issues. However i run 80% tula and 15% wolf ammo through it. Have always wondered about running an H2 but i'm not sure the TULA has enough power to cycle everything smoothly. I'm sure running real ammo with an H2 is fine, and crappy ammo with an H certainly is. Don't know why you'd ever need a carbine buffer in a 16" DI gun honestly- strange most recreational ar's come with them.

    A5H3 on 14.5" BCM Mid - I ran a class with it with no issues, this is with full pressured 5.56 ammo though.
