    Why don’t you do a 13.7” upper?

    A 10.5 to 12.5 pistol with brace would make for a a good truck gun. Or possibly the size mentioned above... maybe price a BCM

    BCM 11.5” barrels are notoriously over gassed. The pistol you’re referring to that was linked is a factory built knights upper and factory built knights lower.

    Let’s both agree on an 11.5” for the guy haha. But seriously I think an 11.5” with a brace would be a great truck gun. If he does go this route he should look at Rosco Manufacturing barrels

    Absolutely not...they don’t make a pistol. Some of the KAC dealers put them together to sell like that. The good ones don’t. Look at KAC’s website. You’re wrong.

    Sorry to disagree. A lot of us would love for them to go that route but they have no interest in doing so.

    It is my understanding that Chuck takes off the cheesy Moe stock (unloads them separately) and installs a brace to complete the requirements of the stock Knight’s lowers that he makes into pistol lowers. It’s all administrative stuff. The upper and lower are still the same contract parts that the full auto room clearing folks prefer.

    I don’t disagree with your comment but Knight’s does not make a factory built pistol. So advertising it as such is false. I’m sure it’s a really good pistol but price is still over the OP’s price point. Plus, if I’m spending the money, I want a factory built KAC. There is a reason there are only a few KAC authorized service companies. They are required to go through a KAC certification course.

    But this if off topic. I apologize for my ability to screw up someone else’s fact finding. Now, back to the OP’s fact finding...

    So if you replace the stock that comes on a rifle, by your logic it no longer a factory built rifle? Swapping the stock/brace does not alter the lower receiver in any way whatsoever nor affect its build quality. Insinuating or bringing up the fact that only a certified armorer can make such a change is laughable...and a moot point since Chuck is a certified knights armorer like the rest of their dealers.

    Those lowers are 100% factory built/assembled, the only difference is he swaps out the buttstock. That is a fact.

    OP I would still go with a BCM 11.5 pistol for your use. They are a little over you max but BCM is a good/quality build point. Over gassed doesn’t really start to make a difference until you get into shooting suppressed. Best of luck.

    What about increased wear on the lugs, gas rings, and buffer spring? What about the effects on felt recoil/muzzle climb? Those are the draw backs of an oversized gas port. While adding a suppressor will exacerbate the issues, it’s disingenuous or ignorant to say they only manifest as a result.

    Most manufacturers are over gassed in order to run both weak 223 and full power 5.56. It is what it is... Lets stop this play by play thing and allow the OP to make a decision on his needs.

    There are so many good choices in the AR arena today it is bewildering when you first get into them. I know because I'm a newbie navigating my way through this maze. I went a different path for something akin to what the OP is looking for. I have a virgin lower that I am building up with a SMP4 brace and popping an 11.85" PWS MK111 Mod2-M long stroke gas piston upper in .223 Wylde on it. This has a 3 position adjustable gas block. Going to put an OSS supressor on it - these are radial in design and vent gasses out the front so they have minimal increases in gas pressure. I'll have the whole pistol together this week, minus the suppressor.

    I don’t know what you mean by “play by play thing”. I know far more about ar’s then I do 1911’s so I go out of my way to spread accurate information on this forum. Oversimplifying (ie overgassed is only an issue if suppressed) is just as bad as over complicating (ie changing stocks need a certified armorer).

    I’m ensuring OP like ever other ar thread is being filled with the right information and I’m correcting the wrong. If you take offense to being corrected, then maybe research before you post and stop sharing your opinion as if it’s a fact.

    For the money BCM is one of the best options in my opinion. Great stuff and a good company IMO

    Would running an adjustable gas block help the over gassed issue from BCM?
