There was a time I thought I just had to have a 45acp carbine. I researched the idea, to death! Only to realize I wasn't going to get much advantage, ballistically, if I did,... so, I didn't.

Then I came across some info on the 45 Super caliber,... same bullet, same case, same chamber. I tried to do it in a pistol, with fair results, but, nothing to get all excited about.

My point?

I think a 45 Super caliber carbine would be very nice, indeed!!!

Just a suggestion,... enjoy! A great improvement over the 45acp, imo!

Also, FYI,... I forgot to mention,... with 45acp carbine ballistics not meeting my goal,... I went with 300 BLKOUT.

So not exactly what you are asking for but...

I have a MechTech 45acp upper mated to a Charles Daly 1911 lower and it has been flawless for years. Only downside is the 10 rnd mag limit.

 

[weenis]

whats the issues

Wrong caliber.

 

[Elk34]

I know Young Manufacturing is working on a DI 45 acp ar15 in pistol or rifle.

 

[delta6]

whats the issues

Wrong caliber.

Wrong caliber for What?

 

[knockonit]

some fella was chatting up a super 45, perhaps that was the reference

 

[shooter444]

Hmmm,... it's the same caliber gentlemen,... same bullet, same diameter, same brass length, same chamber measurements,... just loaded for more velocity,... what's the big diff?

I have a DI Macon Armory 45ACP upper. With my Osprey Suppressor it is almost Hollywood quiet.
Rudy over at Macon Armory is very knowledgeable and could set you up easily with a DI or blowback 45 carbine.

I'm running a 5" Olympic upper on a SBR lower with a Form 1 suppressor. It is a lot of fun to shoot.

I built up an Olympic blowback upper on a Cav Arms MKII lower so I could use a bunch of grease gun mags I had.



I then decided to get a dedicated GG mag lower for it and got a CNC lower finished for it. I also took the opportunity to update the upper with a different forearm and optic.



I have been extremely happy with this and it is a ton of fun to shoot. I have had no real issues with it and it has been reliable for me. I shoot mostly cast bullets in it (200 SWC's and 230 FP's) and other than eventually needing cleaning (blowback can get dirty depending on the ammo) it is great.

intel, a little more detail if time allows, length of barrel, buffer weight, ect.
i'm wanting to do a carbine length barrel, so have been reading nightmare tales of getting it "right", so more info is just a lot of help. and the biggy is finding a 16inch barrel in stock somewhere. that doens't cost as much as full built upper.

thanks to all for info

RJ, it is a regular 16 inch barrel and a regular carbine buffer (I think) and spring. Back when I built it (15 or so years ago) There wasn't many choices for components because "PCC" wasn't a thing back then. I didn't know there were any issues with .45 ACP PPC's? I put mine together and started shooting it. I would guess it has to do with magazine/feeding issues like people wave with the 9mm PCC's. I needed to put in the little feed ramp to make my Glock mag 9mm PCC work.

No problem with questions, happy to help if I can.

good read for sure

Yah,... I was surprised to find that someone makes a delayed blow back 45acp upper.

With that type of action, I would think it would be perfect for experimenting in 45Super reloads.
