    Just here to second everything Furbyballer said regarding brakes vs. flash hiders.

    If you are thinking a SF mini won't suppress well enough for your needs, you want no part of a 6933 fired with a brake on it. It's a lot like firing a 12 ga. in an elevator, just punishing.

    I'd run a FH and remember you probably aren't going to put enough rounds through it to wear out any suppressor. SF cans are a long way from the old "mesh and wipes" stuff from 40 years ago.
    It's hard to be a ACLU hating, philosophically Libertarian, socially liberal, fiscally conservative, scientifically grounded, agnostic, porn admiring gun owner who believes in self determination.

    Chuck, we miss ya man.

    Long story short: Left my old agency last month and joined a new, very progressive PD this month. Day 2 of my employment, they roll out a new policy ONLY allowing suppressed SBR's (so much for the new 6920 I bought). Due to a hearing loss incident from a previous shooting involving rifles, they have called it a risk management and health issue and got the city on board with purchasing FN SBR's and Sig Suppressors for each car (we rotate cars, no take homes). Now, we all need to use the guns in the trucks until we have our own Suppressed SBRs. I am not hot on sharing a rifle, as I like to know that its zeroed and maintained by me and no one else.

    UPDATED: So, here's my plan:

    Colt 6933

    Surefire SOCOM 556 RC2

    Does this seem like a solid plan for a gun that will be run suppressed all the time? What changes will I need to make to the 6933 to make it more reliable, if any?

    Your department is ran by morons.

    They selected the FN and SIG silencer hoping they can just marry these two things together without any thought put into gas port, buffers, ammo choice, etc.

    Having your gun suppressed all the time is an unrealistic situation.

    If you buy a 6933, you will have to get an H3 buffer and possibly a LMT enhanced carrier to vent excessive gas depending on what ammo you are shooting supressed.

    What?

    A 6945 uses a regular carbine stock.

    I have the 6720 & 6945, both are ported to run with a can very smooth. I have run a SIG QD 556 suppressor. If you want to improve reliability add the Vltor A5 buffer and possible a LMT enhanced carrier when you get more funds. SteyrAUG did you a solid on looking at the 6945, that FSB is the closest thing to a fixed sight, its bullet proof. Nontheless, your 6933 is a great choice. Add the above goodies when you can. Good luck with your rifle, looks like your well on your way to great stick.

    Sorry, when I googled the 6945, the link to Colt's site came up with this:

    I think that's an unfair assessment. Cops are generally not gun guys, and tend to listen to the guys behind the counter at the gun shops. These are good SBR's with good cans, nothing great about either option. I consider myself a pretty knowledgable gun guy and still didnt know anything about these things until this thread. I'm sure there will be growing pains with the new rifle/can combos, and we'll get them fixed. We are going from 20 year old Bushmasters to this, so progress is being made in the right direction, which is rare for LE agencies. Most gun owners, regardless of profession, never pay attention to NFA items and how they work because of how difficult they are to obtain.

    Thanks PB, that's good info to have. I'm God knows how many months out, but I think I'll try it in the stock setup with the can and then just problem solve from there if there are issues, starting with the H3 buffer or A5 system.

    That's a good approach. Those upgrades are often not critical but make it smoother or more Reliable. Kinda go from good to great. Your gun should run fine because your buying quality stuff. I corrected my first post in that I cornfused my Colts. I have the 6945 and 16' inch 6720 skinny barrel, I don't own the 6933 but I'm sure you will be pleased.

    And to be honest, the dept buying FN and Sig cans sounds like a huge upgrade from Bushmasters. Too bad you don't get your own. I could certainly live with that combo if it was my own to tweak.

    The issue is I don't foresee anyone in your department spending time/effort/money into getting these guns and silencers to operate correctly with each other.

    Who is going to control what ammo is used in these guns? Who is going to order new buffers? Who is going to install the silencer mounts? Etc?

    They were ordered with the false understanding the silencers would be attached to the guns with no extra effort required. How do I know this? Its because the person who picked these out knows nothing about this stuff, because he didn't pick the right gun and silencer brands to begin with.

    The easiest solution your department should have done was order KAC 11.5" guns with KAC silencers. That would have eliminated anyone having to fiddle **** with them that didn't know what they were doing.

    Your said your new department is very progressive and forward thinking. Your department issuing "community" guns is not progressive. This is regressive and backwards. Your department is acting like a bureaucracy dealing with a government property control and inventory problem.

    You are on the correct path with buying your own Colt and Surefire. Your department isn't.

    I suppose neither of us can predict the future. Maybe, with the help of you guys on M4C, I can try to advise when problems arise.

    Consider getting a 6920 barrel cut down and threaded at some point. Don't touch the gas port and have a dedicated suppressed carbine that runs so much better.

    Yes, cutting down a 16" barrel is a great option.

    Another is using our CustomTune gas port in the FSB.

    Both of these options correctly address the gas port size, which you'll want to do for best reliability and function of your dedicated suppressed SBR.

    This will also eliminate the need for special buffers, springs, carriers and charging handles, which are often recommended and tried in an attempt to compensate for severe over gassing.
