    asking for some expert advice here - I'm building up a 10.5" SBR (Noveske barrel) and plan on getting a suppressor down the road (sooner than later, but we know how that usually plays out)

    with the SBR should I get an H2, I'm thinking the H3 is a little too heavy? Feel free to correct me?

    You'll just have to try it out. I always thought that running the H3 was for KNS pin user types who worry too much, and that it'd just create more issues than it would fix. But I think it has actually tamed my SBR.

    I've been running it with both full power military ammo, some factory .223, and some of my pretty mild hand loads. It seems to function fine across the board.... which is the only acceptable way a gun that I own will run.

    You'll just have to try the buffers and see how it runs.

    I voted H3, but I am getting ready to demo a Slash extra heavy buffer in my suppressed 5.56 SBR, as well as my suppressed 9mm SBR. It weighs in at 6.5oz.

    I suspect that my cyclic rate is going to go way down, and I'm hoping to see more consistent extraction.

    I will post a review soon.

    Well Noveske sends their complete 10.5" rifles out with H2 buffers with a standard spring. I'm currently running an H with CS spring in mine as that's what Grant recommended with the Noveske barrel and it's been running well since I got it.

    Granted I only have 300 rds through it so far, but my Colt 6921CQB (10.3" barrel) has an H3 buffer. No issues yet...have shot XM193 and Federal AE223. More after my LT forend gets here on Tue and I can install it.

    I have an LMT 10.5 with a Noveske Krink set up on an LMT lower. Standard LMT carbine buffer as far as I know (will check later). I've got about 400 rounds through it without a problem, but it's all slow fire at my local range. Not planning to shot this carbine suppressed.

    Question: what function check do you use to test for optimal buffer weight? When will problems show up if the buffer / upper / ammo combo aren't optimal? Fast shooting drills, or ???

    I'm attending a three day class next month and I'm thinking about buying an H buffer to have in the spare parts kit for when something goes wrong (just not sure how problems manifest RE: buffer weight).

    Put one round in a magazine and chamber the round. Fire the weapon. Does the BCG lock back? If so, then you are GTG.

    Generally on a 10.5, I would use an H (minimum) and really go with an H2.

    This might sound dumb but I'm learning

    What, if any affect do these changes in buffer weight and spring tension have on velocity and or accuracy?

    Nothing on velocity. Maybe you could realize faster and more accurate follow up shots with a buffer that tamed recoil a bit.

    I read in some magazine that the Colt M4A1 carbine with a 14.5 inches barrel has a H2 buffer?Is this true?The reason for me asking this question is because I have one and a couple of days ago,I just placed an order for an LMT Sopmod buttstock with an H2 buffer.I just hope that it won't cause my Colt M4A1 carbine to mulfunction.
    Thanks.
