    Keep a suppressed SBR running in a class?

    Anyone have general tips for keeping a suppressed SBR running for the length of a 1-day carbine class? I've got what I feel is a quality build, with the heart being a DD barrel and BCG, but it gets really dirty even after a few mags at the range. Brass comes out filthy. The most rounds I've shot maybe 150 rounds through it in a single session, but we're talking 500+ rounds in a day-long class. The only stoppage I can really remember was after cleaning it, not lubing it at all and running it bone dry. It choked after a couple mags. Should I have some sort of aerosol CLP or gunblaster with me to hose it out, or is keeping the BCG wet with CLP through the ejection port going to be enough? I'd like to spend class time learning and shooting instead of worrying about a gunked up gun, so any advice is appreciated.

    Also, any trouble keeping the can on that whole time? It's an AAC 762SD. I know it's gonna get hot and might have some finish damage by the end of the day, but I assume those cans can hold up to anything my DD pencil barrel will take. It's a beast without the can and 500 rounds unsuppressed would suck.

    Well this will sound like a shameless plug, but I am throwing it out there. Get some FrogLube and lube the shit out of your AR. That's what I do and I ran my SBR well over 600 rounds per day during Magpul Dynamics with virtually no cleaning.

    What he said^^^ Lube the shit out of it.

    Running dry is retarded and will result in failures.

    You're good bro.

    Rock on and don't listen to a certain internet whacko on this forum tell you otherwise.
    Why do the loudest do the least?

    Lines aside... If you're running a suppress sbr, you need to limit your gas, no way around it. You have too much gas pressure.

    Adjustable regulator like a JP but that pretty much requires you do only run supressed. A Noveske Switchblock that if you have the right rail and port location is a great option. And the W.A.R. Upper receiver does the same thing but allow use of any rail, this is vaporware so far though.

    I disagree. You simply need a properly built SBR.

    It is actually. Anyone that's honestly spent any time shooting suppressed short DI ARs can tell you the gassing is not imaginary and does not mean gun is not a "properly built SBR". You're high on koolaid if you think a Colt SBR won't gas the shit out of you.

    Shooting with the switchbock is night and day suppressed. From the gassing in my eyes, how dirty the mags are, the location that spend brass is landing, recoil impulse.

    This isn't a question of being a "properly built SBR" unless you require have a means to regulate the gas. If that's the case, yea, I'd agree an adjustable regulator is part of a "properly built SBR".

    For what it's worth... My during ban Colt HBar that I had threaded later... gasses me worth than any other 16" gun I've used. Not sure why, but it's noticeable. My Colt must not be as properly built as the 16" Stag I tried the same can on, right?

    There is no way in hell I'd take a can to a class without an adjustable regulator. Either LaRue, Noveske, or Other. NOOOOPE.

    Here's a thought. Check yourself, before you wreck yourself.
