Anyone have any comments on using Colt 9mm carbines? Very expensive, of course, but are users generally satisfied with them?
Thanks.
I have one and I am very pleased with it. Shoots great.

I have one …The ONLY regret I have in owning a 6450 is I wished I purchased it in 1991 like I did my Colt HBAR for $650 (I got it and a 1000 rounds of Norinco for $750 cash out the door !!).
I did casually look at one back then and unknowingly snubbed it … I thought “WHY would anyone want THAT!!!” Absolutely love the 9mm AR’s. Huge fun. I also bunny hunt w/ mine and play PCC.

I have one. I’ve only shot it very little but it’s run without issue when I have shot it. I think I have a couple hundred rounds through it tops. About half of that was shot suppressed with a YHM can on the end, the other half was initial sight in and function check.
If my new Anvil/RRA 9mm SBR runs as well I’ll be selling off the Colt.
Here it is with the can on it.

Rob, I have read on TYV about your Anvil Arms SBR, but I have to wonder why not just SBR your Colt?
Primary reason originally was that I didn’t want to mark the lower.
I see.
Those are great looking rifles and I do want to buy a Colt 6450. I noticed your upper looks modified. That hudge Brass deflector is gone and I thought it was part of the upper, meaning you cant move it. Pls explain how you removed yours and the way it is attached originaly.
Scattergun!
I have one and I am very pleased with it. Shoots great.

Thx
The upper receiver on Colt 6450 9mm doesn’t have a deflector made into it like the
A2 and later 5.56mm uppers do. They have a plastic deflector/shield that
attaches to the port door hinge pin. I think this plastic deflector/shield
looks like a cheap after thought. It is easy to remove by removing the “E”
clip on the front of the port door hinge pin and pulling the pin out. Once
you do this you will also need to replace the short port door with a
standard size door. My gun ejects the brass forward and to the right on
about a 45 degree angle so removing the deflector/shield was not a problem
on mine. The deflector/shield is also supposed to block any gas that blows
out of the port during firing. I have never had any problem with this issue
either.
Like Scattergun I also removed the ugly plastic clam shell on my 6450. I have not been hit with anything since the removal. Cases land Way out @ 3 o’clock. I have not even replaced the door yet. I love the old A1 look.

I have a 6450. i got a good deal and bought it for the lower for my SBR project. I immediately replaced the upper with a larue upper, w a noveske barrel and larue hg (after my stamp came back of course). It is actually my wife’s gun, but ammo costs being what they are I’ll probably be using it at a few classes this year. It runs like a champ; about 10% of my CProduct mags have issues and will be going back
Well after holding, touching and smelling a colt 6450 in a store today, I had to have one. This rifle is much nicer in person but the price was to high so I went back online to a company where the price was at least 350.00 cheaper and bought it. It might be in my hands by this Friday or next Monday. ![]()
You wont regret that purchase. I have one and it’s a great shooter. Also the perfect rifle to introduce new shooters to EBR’s.
I inherited a Law Enforement marked Colt 6450 about a year ago. When I first got it, I thought, “what the heck is the point?” I was resolved to sell it. Well I waited and never got around to selling it for sentimental reasons really.
Then I took it out for a spin on the range. I LOVE IT! I have to say, it is awesome. Super light, suprisingly accurate (remember its a 9MM)
I reload, so my 9mm is SUPER cheap to shoot. Get one, you won’t regret it.
I too put my nose up at the 6450 and didnt even consider this rifle a couple years ago. I began looking into them and thought what the heck so I purchased one and its great. My lower is maked Colt Defense with the LEO markings current production and the finish is great.
I only shot from 50 yards but I hit dead center with a grouping the size of a small fist. I was using Magtech 115 gr full metal and had no issues. I shot 100 rounds and now I want to reload for this weapon. ![]()
I dont know much about reloading anymore but do have a Dillon Square deal I purchased in 1992 set for 40 cal. I need to check if I can switch out dies for the 9MM.
I found a new colt 9mm carbine at a gun store today for $1299. I feel like a fool for not buying. I’m guessing that was a pretty good price considering the times.![]()
You’re likely right. Whatever does or does not happen to us legislatively, it seems clear that demand will remain consistently high from this point forward, and a return to the days of “reasonable” pricing is probably not in the cards. Rather than grouse about that, I guess I should just be grateful that, for now, the window of opportunity is still open at all.

If your gonna go 9mm go Colt, you will not be disappointed.

I’m wanting to build a 9mm 7-10" suppressed M4 that uses Uzi mags. Can anyone give me ideas as to where the best places are to purchase the parts I need to make this happen? I have been wanting to build this weapon for a long time.
When you say M4 you are meaning a flat top? Look at the link. Parts are hard to come by at this point. Grant has a built up option available now. You will need to find a bolt (RRA) and a mag block (Hann, RRA, Colt). If your lower does not have a 9mm hammer and heavy buffer then you will need that also.
