Colt 9mm AR VS newer 9mm carbine options. Login/Join 
Prepared for the Worst, Providing the Best

I've been watching this thread with some degree of interest. I also like the idea of a 9mm carbine, for reasons similar to those of the OP, as well as the fact that my club only has one bay that I can shoot center-fire rifle on, but a PCC opens up several more options.

I had a PSA 9mm AR, and it was not a good experience. I had all kinds of problems, including doubling and out-of battery discharges. It liked one kind of ammo, and that kind only. I tried all kinds of different springs and buffers, to no avail. The final straw was when it OOBed on one of my co-workers during a range day. Thankfully he was unhurt, but I ended up trading it off with full disclosure, at a huge loss.

I also had a Ruger PC carbine. I didn't like the fact that it took screws to disassemble for cleaning, and the chintzy takedown lock ring was not confidence inspiring. The recoil was also pretty stout for what it was...the butt-pad would actually bruise your shoulder. It was reliable, though, and never blew up cases in my face. I'd probably still have that one, except I decided I didn't need 2 9mm carbines and traded it off during a period when I thought the AR9 was fixed. Then 2 weeks later I had another OOB discharge with the AR9.

After those two experiences, I've sworn off blowback carbines. I'm tentatively saving for an MPX right now, but I'd take a PTR 9CT if one came along at the right price at the right time.

A buddy got one of those 9mm AK pistols (not the PSA one...the one from Atlantic Firearms). It's blowback, but he swears it's reliable and incredibly soft-shooting. I'm still needing to find a time to go shoot it with him. It's going to have to be something really special to get me to drop cash on another blowback gun.

I've also thought about building another AR with the CMMG Radially-delayed blowback system. I was looking at those the other night when I came across something about MEAN Arms developing a roller-delayed blowback AR upper...now I'm thinking I need to wait and see where they go with that.

I have a pre-ban Colt, AR, 9mm and a Ruger PCC in the standard configuration. I think the Ruger is more fun to shoot.

Where are you going to find a Colt 9mm carbine nowadays? It’s the gunpocalypse. Good luck.

I have one. It’s not very reliable. Every other 9mm carbine I have has been 100% reliable. The Colt? Not so much.

Probably not the topic for this thread, but I have never seen a true factory unbuggered colt that is not gtg. Personally (I have quite a few) and my local guys used them for quite awhile without issue. What exactly is wrong with yours, it can easily be fixed.

I've used this BTE 9mm for some time now. It uses H&K MP5 mags and I find it very reliable. I've also got a B&T GHM9 Compact, which (although very well constructed) just doesn't feel as comfortable to me as the AR 9mm. I'm also in the process of getting a stamp for B&T's conversion to SBR status.

What bolt are you running? I was recently given a quarter circle lower that takes MP5 mags, but have yet to put an upper on it yet. QC10's bolt is $225, but I haven't see any others that claim compatibility with MP5 mags.

I remember when you were building that rifle, still looks so damn sexy!

I think I am going to buy a CMMG bolt/barrel combo, use the Endomags and one of my SBR lower so I don't have to worry about paying for another tax stamp. I'm debating on 8" or the 4-5".

just saying not a lot of room to hold onto things in the 4" ones.

I put a much longer handguard on my 5" Banshee 9mm.

Big enough to shroud the suppressor that I plan to build once I get my Form 1.

But yes, a VFG or something similar is desirable on the super shorties.

It's not a Colt pattern, but I'll play. Built this off a QC10 Glock lower a while back, they make Colt pattern lowers too. Other than it being extremely tight, I've had no problems out of it. I do like the B&T offerings, but I don't need another 9mm anytime soon. Had they been out when I ventured down this rabbit hole, probably would have picked one up instead.

My Glock lower PSA 9mm. In hindsight, I wish I had spent a little more for an upper in the 8-10@ range to give the cartridge a little more umph, but the price at the time was well under $100 at the time for this one. It’s been reliable and makes for a easy to travel with little guy. No complaint

I really like the Colt AR style 9mm PCC's. Here's one I built up from parts.

Not really because being that short it balances at the mag well.

Wouldn't be my choice of setup for sure. but ok. sling mounts, light possibility, backup irons, some place for the hands etc. not really happening. BUT the great part of these PCC guns is you can do what you like.

I never really wanted an AR9 due to the Glock mags looking kinda funky on an AR.
Then I seen a PSA 8" upper for sale locally that came with 3 Pmags with Endomag inserts.
Did some research on them and picked it up, stopped and grabbed a lower and ordered a few parts.
Already had a bunch of spare parts and a half hour later.




The A5H4 buffer will be here in a couple of hours, I put an A5H2 buffer in it just to see how it cycled and if it would need a spacer.
The Vltor A5 buffer, rifle spring and carbine tube is a perfect fit for an AR9.

The PSA AR9 BCG worked out with the Law Tactical folder too.
Once the pin and slug were removed the adapter went right in and weighs .4 oz less than the slug.


The Magpul MS4 sling I have worked out as a single point on it better than a full size rifle and will use it on it instead of my weed eater now.

The bolt on my Battle Tested Equipment is made by BTE and their part number is: 9mm-BCG

8” barrel, 7.2” rail, and direct thread suppressor.
The three lug adapter for the TiRant is like $200 if you can even find them. I don’t swap it out often to justify the cost.
