    The LWRC (and I assume the POF and HK416) carbines run cooler and much cleaner than your guns suppressed or unsuppressed. After a long firing string (such as found in a protracted engagement or training evolution) you don't find that the lube has either turned into some sort of carbon sludge or been cooked off altogether. That may not be an issue for you. If it's not then you've got nothing to worry about. I've never, ever claimed that companies like LMT or Colt make bad guns. They make great direct impingement weapons. Hell, I look forward to trying out the LMT Piston MRP or Colt 1020. I have come to the logical conclusion that properly engineered piston operated M4/Mk18 carbines are better though; specifically the LWRC M6A2 carbine.

    A harmless puff of gas in your face is a hell of a lot different than getting particulate matter in your eyes.
    I'm refering to the noxious gases and not any sort of debris or particulate. I find that it is not bad in mid/rifle length DI systems suppressed or otherwise. In carbines I find it very distracting/annoying.

    I will conceed to Stephen the cooler running of the piston (at least in the bolt area).

    However I tend to question the NEED. Its nice, and dont get me wrong I think than any way to make the system run smoother in a the long run is a good thing. The issue I question is the push of the view that this is a DIRE need.

    I've shot a few suppressed M16FOW guns - from M2 Corp 4" PDW's to 20" rifles.
    In Afghanistan we took turns with my Mk18 at the range one day (I was going home the next day - and we where having fun)
    We put over 300rds of Mk262 and closer to 3200 rds of M855 thru it suppressed.






    We had to keep running back to the truck for ammo and mag loading.
    The suppressor blew sometime into the 2k frame. But the gun kept running.
    The gun was LIBERALLY lubed with Breakfree CLP intially - and again at lunch.
    However the three of us shot all our basic loadout thru the gun intiallu without any hickups, 24+ mags.
    Now I know you (Stephen) have been in ground combat in Iraq -- did you personally need 24 mags at once? Of course not.
    So what the piston does is give you a fudge factor (of maybe 20x) for operations -- and also makes your daily dust n' rust cleaning and after use clean a heck of a lot easier.

    I'm getting another 2 Hk416's and if Darren would ever return my email I'll be getting a LWRC 12.5. However I dont think I NEED them*.

    Okay now I am really confused If you (an obvious combat veteran) say you would get a piston AR if the zombies attack and you are getting the HK416 (which I think is a piston AR) and a LWRC 12.5" rifle then doesnt that mean that piston type rifles are good rifles. I dont need an AR, but I do want one. I want one that will provid me the piece of mind that if I ever 'really' need an AR type weapon that I will have the one that is 'really' up to the task.
    ***shaking head ** Now I have to go back and re-evaluate the pro and cons of piston vs. DI ARs. The more I learn the more tenative I become because I dont want to waste my pennies

    Often in my life, I've been happier when I stopped thinking and just wrote the damn check!

    I short Kevin B was joking about the Zombies part. Zombies don't exist... Now Vampires are another story.

    You will be fine with a LMT. FWIW the US military primarily uses DI guns for the past 40 years (although they have been upgraded and revised through the years.) The DI system is time tested, combat proven, and will serve you well for range sessions or home defense. There's no need to rethink the entire thing honestly. Go with a Colt 6920 or a LMT for the more bang for the buck model. A mid-length 16" barrel is a good choice for a general purpose weapon.

    Zombies move to slow to cause me to much concern. Its those dam Werewolves and other creatures of the night that I am really worried about. The ones I can out run. I would hate to have to push my girlfriend down as bate so I could get away and get my AR

    LWRC's, LMT's, Colt's (and many others) are "up to the task" you dont have anything to worry about there. When you say "up to the task" Im guessing you mean that the gun is reliable and wont give out if you push the envelope a little, maybe by not cleaning it as often as you should, etc... LWRC claims to have test rifles that have shot 70,000 rounds without piston related failures or maintenance, with a wipe down of interals every 5,000 rounds I think it was. So if your looking for reliability I think thats preeetty good. Need is the key word here. Half of us who own these weapons dont need them like our fighting men and women do. So to say you need a piston rifle may not be true. You have the same chances as any of us do of whatever weapon you buy to go forever or just go for awhile. Whatever you buy, keep it clean that always helps. One things for sure, it will run til it dont.
