    OK the truth be told, I did fire about half a case of M855 thru my Mk 18 today, and 750 Win/Ranger thru the Sig. I hurts to type.

    And I did it with a stock action spring and H buffer, no suppressor

    Slumming, huh?

    Edit: don't mind me - I'm feeling a bit testy today - quit smoking four days ago :-)

    No prob, Bro

    And I should add no Crane O Ring, but I was using H&K mags.

    All I did was add some lube(Rem Oil) every so often. Didnt even use a chamber brush. I would say the weapon went about 1200 rounds without cleaning the chamber. I had no jams what so ever.

    I guess the point im trying to make is that you dont need all the extra bells and whistles, up to the point that the weapon wont run reliably without the extras, then use them to keep the weapon reliable. Just like you dont use "Over 100,000 mile" motor oil on a brand new vehicle.

    Dude,
    You need to hook a brother up! I can help you deplete some ammo!

    I just installed the ARES G35 piston conversion on my Mk18'ish LMT and I'm having the KAC RAS2 top rail milled tomorrow to fit over it. I had thought of getting a VLTOR CASV-EL which is cool but probably would require milling to fit as well.

    I put an ISMI spring and H2 buffer on my middy a couple of weeks ago and was very happy with the performance. Everything ran great even Wolf ammo. Went to the range today and the crazy thing would short stroke Wolf ammo about every fourth shot or so.

    I was highly confused until I remembered that I changed out my stock flash hider for a Smith Vortex after my last range trip. Could a flash hider change make a difference in bolt cycling? The only other thing that changed was the temp. It was much cooler last time I went out.

    Ive had the same problem , I was breaking in an m4 with wolf ammo, during multiple range trips. I was new to the game. I think it's the wolf powder residue, it kinda gums up the gas tube after you let it sit any length of time after you shoot. What I do to resolve the problem is at the end of my range or training session I shoot some good ole high pressure 5.56 to blow the wolf crap out of my gas tube. It's the easiest way to clean your gas tube. I hope it works for you!

    I just read on the David Tubbs website that there CS springs are not recommended for use with low power ammo. The ISMI spring I have seems pretty heavy, it may have the same problem. I will probably go back to a standard spring or one of the Brownells CS springs in my Middy, since I use Wolf ammo alot.

    Well guys,
    Let me say that I bought some brand new, Black Hills (red box) .223 ammo, in 68gr Sierra Matchking BTHP today, and I "single shot" all 50 rds today, with not a single issue locking back.
    The gun performed flawless with the ISMI spring and H2 buffer. I think it was the ammo I had been shooting before.
    The problematic ammo, was actually some that I had THOUGHT to be decent ammo, due to many of my buddies having excellent experiences with it. Said ammo was from GA Arms, and yes, I know of the problems some of the board members have had with it, with double powder charges and whatnot.
    I too, had a shell that malfunctioned, but that is another thread entirely...

    Can anyone here tell me WHAT exactly is considered to be "low power ammo"????? I mean, is ALL .223 factory ammo considered "low power", and all 5.56 ammo considered "high power"????


    Also, can anyone tell me where I can obtain some Mk262 ammo?
    I mean, IF not available, then how much different would the .223 Black Hills 77gr Sierra Matchking BTHP ammo be, from the 5.56???? What is the exact difference between the two, and how will the two rounds most likely perform in comparison with one another??? (I realize true testing will only reveal the definite results, so I'm looking for approximates here)...

    Mk262 - www.goarmy.com or http://careers.state.gov/

    Blackhills was selling seconds IIRC -- but those two links are the two ways I have gotten Mk262

    I ended up with a few rounds of Mk262 in my kit on the way home from Afghan (accidently I swear) - I chrono'd it over the 77gr Red Box BH stuff I had -- aprox 150fps faster the NATO load was over the .223
