    Troy M7 16'' CQB Upper receiver barrels.

    First off - 16'' and CQB should never be in the same place together.

    Second - Is NiCorr becoming more popular? They're the second maker I've seen this from. I love this coating (Amazing on LWRCi rifles) and was wondering if anybody knows where I can get it done. If it's available.

    Third - Not that I'm considering buying one, but what's the general consensus on Troy AR uppers?

    People use 16" for CQB every day. The military uses 20" for CQB, and quite effectively. NiCor, I know nothing about, but LWRC is using it and they make some very high quality guns.

    Nicorr is not a finish.

    It's a metal nitride treatment.

    I believe it will become more popular. When done right it is viable compared to chrome and phosphate with some tangible benefits

    Do you know where standalone NiCorr treated barrels can be bought?

    I appreciate the post, but I wouldn't touch anything DSA for a life saving gun.

    Kyle Defoor has a couple of entries on his blog Re: the 16" Troy CQB upper. He just built up a new carbine wearing the new Troy upper after shooting out the barrel on his DDM4.

    Off the top of my head, I can't name anyone selling nitride barrels

    You might want to give Spikes a call. They are doing 4150 cold hammer forged Melonite treated barrels, which basically is the same process as nitride.

    In a nutshell here are the suggested benefits of a nitride treated barrel

    1. Tighter tolerances because the barrel is not over-bored to accommodate the chrome lining layer, which in theory translates to better accuracy

    2. Barrel is near impervious to rust inside and out

    3. Color can't be worn off like traditional barrel phosphate. The barrel steel is actually treated

    4. No chrome lining.

    5. Better barrel life due to incredible surface hardness.

    6. Barrel should be cheaper due to no chrome lining or phosphate

    Are KAC barrels nitrated or CL?

    If so, then this is a non issue for me.

    ETA: I meant to say CL but put CHF. I don't know why.

    I've done about 6 nitrided barrels for SPR's so far. Results have been very good. It is cheaper than chrome, but in small numbers it's still pricey.

    Let me know if you all have any questions I can answer.
