    I get it. I carried an M16A2 and an M4 in the late-90s and early-00s but I have no burning desire to replicate either one. If I have anything that's similar in style, it's a coincidence and not anything done out of nostalgia. Do you think you would have a different opinion if you'd had more positive experiences with them?

    This build and getting quality parts into my "good" carbine are the priorities on my AR to-do list. They are also probably the only things on that list that stand a realistic chance of getting done despite all my ohhing and ahhing over and want of an AR45, something in .450 Bushmaster and a 6.5 Grendel.

    Read a wrong, but I didn't explain it well - Sorry two fold problem:

    1) I thought the Colt SMG was an open bolt design originally, and the closed bolt was just the semi-auto version. Most open bolt SMGs don't lock back on empty, so it's just kind of superfluous to have one that does. I had been told in the past Colt added the bolt catch later, per some agency request. In other words, I thought the odd 9mm-specific bolt catch was a later addition, because the original design really didn't need one.

    2) It turns out it is a closed bolt design, period. Which means, instead of making a magazine block design that uses the original AR15/M16 bolt catch, Colt opted to make a modified 9mm-specific bolt catch. And why they did it that way is anyone's guess. Particularly when we have modern magazine blocks that do not require the 9mm catch, it's not a difficult machining problem, I'm sure Colt could figure it out.

    I suppose it could still be that it wasn't part of the original specs and was added later.

    __

    And yea, the AR9/Colt SMG definitely isn't an MP5 or Sterling or Swedish K, or I guess APC9...It's more like a Grease Gun or Uzi...something made as a stop gap because reasons. But they are fun when they work and can be made to work. But like most blow-back guns, they need lots of mass behind the bolt, lots of lube, and usually heavier/hotter ammo.

    I will never forget the first time I shot an Uzi. I had a major love affair with Uzis as a kid. And someone handed me a transferable Vector on the range and a mag. So, I brought it up to my shoulder and started shooting. Good god...what a pile of unergonomic shit. Grip forces the gun way up, cheek weld? Only if you've got a neck like a brontosaur. The grip safety...it seems to require only 4-tons of grip pressure to deactivate. Also, whoever thought it was a good idea to not let you work the bolt without gripping the grip safety, dumb, makes manipulations difficult. And that sliding safety? Detents are weird, sometimes it clicks, sometimes it doesn't. Then there is the mag release...

    And I remember my heart breaking a bit, kind of like meeting your hero.

    Anyways, when I was done with that mag, I gave it back, picked up a Lage Upper equipped Mac and got back to having fun.

    100%. I have a near mockup of our Mk18s from work sitting next to me right now just because I love'em so much.

    I imagine if we had MP5s general issue, I'd probably have an MP5 too.

    Enough! The Uzi holds a dear spot with our older agents. It was a matter of betrayal when Uzis were taken from service and replaced with Colt SMGs. From the days of porn 'staches and fros:

    Ok this is going to take awhile but I promise to come back OT...

    During the last last scare, on principle, I got a MPA 9mm MAC type that ended up more or less as I expected. Horrible sights but a stock/brace would make it fun.

    Then during the last scare I got a semi Vector UZI. Looks awesome but I ran into every meeting-your-extremely-flawed-hero issue that RevolverRob so eloquently laid out. The clunky semi fire control system only makes it worse. Makes the MPA seem like fine machinery in comparison...

    Of course I also needed an MP5 before the last ban so I got a reverse stretch POF MP5K. Even though I had fun shooting MP5s in the past, when I started putting more rounds downrange I ended up not liking the "rolling" recoil impulse.

    Just for the heck of it I got a couple Scorpion EVOs as well. Not bad. A little bulky with a mediocre trigger but runs 100%.

    I also built the aforementioned QC10 dedicated Glock into a carbine with a Faxon 16", Brownells BCG, HeavyBuffer, and a SSA trigger. AR inline recoil, slim lines, and a G trigger makes for a quick firing and pointing 9mm carbine. In the end it's my favorite fun 9mm long gun.

    See I brought it back on topic!

    Dennis.

    That’s how it starts. Now I don’t even know how many I really have. I found a stripped lower I forgot buying the other day.

    So after lots of detours, delays and quite possibly forgetting about this project (), I ordered the Hahn top loading block and 3 Brownells Colt mags a couple of weeks ago.

    I installed it last week and promptly found out a standard 5.56 mag catch doesn’t have enough reach to lock the mags into the lower. I ordered a 9mm mag catch from RRA last Friday and it arrived today. Not bad at all considering there was a holiday in there.

    Anyway, the new mag catch solved the problem and I ended up with this:

    There’s also a CMMG MK9 lower on the way so there’s probably a carbine in my future as well...

    For those using Glock mags with AR lowers, is there a polymer mag release button that can be used? Similar to how the Shield Glock mags suggest not using their steel mag release with factory polymer mags again.
