I ask, because I simply cannot fathom a system changing that much and not being "broken" somewhere.
    That gas tube was jacked up! There was so much gas leaking at the key and blowing all over the tube, but I couldn't see it under the DD Lite rail. I replaced it and the gun went back to normal funciton. Never did go back and retest any bad ammo... I think I just bought one box... and normally wouldn't shoot that stuff since I hand load everything.

    I still don't know what caused that tube to wear so thin... ??

    Very odd. I detect no abnormal wear on my ddm4 middy tube. It's a 16.1 gun though if it matters.

    I wouldn't expect so. I guess it was just a fluke.

    Sprinco Blue Spring and H Buffer in BCM 16" BFH Mid-Length Gas. Runs very well. Shoots über soft.

    I just don't believe in flukes involving mechanical things. People, yes, but mechanical things, I think always have a cause. Soft tube? Misaligned? Rough gas-key? I feel like something technical is at fault. Likely with the gas-tube and I wouldn't lose sleep, but machines don't randomly do things, IMO. Always a cause. Did you see if the gas-tube was more easily scored than others? Look inside the gas-key? I dunno, just ideas.

    Soft tube was my thought.... that's what I meant by "fluke"

    (not an alignment issue.. I know how to check that, and am too meticulous at poking around in an upper before I ever light a live round up)

    I run a carbine buffer. I was told that the spikes barrel I'm using was on the conservative gas port size. Feels like everything is working alright. Ran a h buffer for a while and the whole action felt sluggish.

    I run a Springco Blue, H2 buffer, "semi-auto" profile BCG on my 16" middie. Shoots pretty soft and so far cycles perfectly with pretty robust ejection at about 2:30-3 O'clock. Haven't shot the really weak ammo yet but have shot about 1K rounds each of Federal Premium 55gr "tactical" duty ammo and 55gr American Eagle practice stuff.

    My Black Hole Weaponry LTM barrel felt a little overgassed when I first shot it with a standard spring and carbine buffer. Shot it back to back with my issued Bushy (16" carbine gas) and didn't see the expected difference in perceived recoil or feel. That changed with the heavier buffer and sprinco blue.

    As an aside, I asked BHW what the spec'd gas port size was on the barrel and they replied .085-.088. That seems a little larger than some of the other sizes I've read about here for a 16" middie.

    I've been considering trying the VLTOR A5 to see if that changes or improves the feel over my current set-up.

    Perfect example of a company that has no idea how to port the barrel. That port is way too large and is approaching rifle port territory.
