The AAC 762-SDN-6 can be used on a 7.5" 5.56 without voiding the warranty, per a telephone conversation I had with AAC when making an order.
As far as a 7.5" AR in general.... Mine works and has run 100% but I don't put a lot of rounds through it. Not very accurate, and without a can but with the PWS fsc556 on it the concussion is teeth rattling.
I think it looks cool, but I'm looking forward to getting my 10.3" Delta Company Arms barrel in 300 AAC to replace the short 5.56 barrel.

The added gas from the silencer overloads the shorter operating system more than a carbine length gas system.
You will want to use at least an 8" barrel and 7" handguard if you want to be able to hold the handguard.
It might be interesting to compare the OAL and sound of a 10.5" with one of the newer mini cans to a 7.5" with a regular size can.
I agree that finding another caliber is the way to go if such a short weapon is needed. Leaving the AR platform completely might be best though... MP5, etc.
Even the PDW caliber rounds like 5.7 are somewhat silly.... better off with a full house 9mm load.

You may have seen this already but in this video they compare the overall length of the MP5 to a AAC 9" 300 blk. IIRC from the video they are using a fixed stock on the MP5 which hurts it....but were talking 230 grns at a 1000 fps vs 145 grns at 850 fps.......

ETA: I have shot 1, 7.5" AR. It was on a FA lower at 50 yards. I didn't have much issue ringing steel on full auto and it ran through the whole mag. This is one sample and it was a Noveske upper.

In regards to this post, do you have any clue who you are talking to? Why don't you ask before talking to someone like. I bet in person this response would have been a HELL OF A LOT different.
Like zushwa, I have an 8" PSD. Not my favorite and I prefer my mk18, but does that make me a ****ing retard??
This shit here is getting stupid.
Proven combat techniques may not be flashy and may require a bit more physical effort on the part of the shooter. Further, they may not win competition matches, but they will help ensure your survival in a shooting or gunfight on the street. ~ Paul Howe
For those that provided meaningful input, thank you. For guys like magic saladtosser, thank you as well, your comment actually made me laugh. Although it was childish and useless, for some reason I found it kind of funny. It takes more than an internet tough guy hiding behind his keyboard to spin me up so it's all good
FWIW, I don't intend to shoot people with it so terminal ballistics are of no concern to me, nor do I plan to do much shooting past 25yds with it so external ballistics aren’t an issue either. It really would be just a "why the **** not" or "because it seems cool" project. I already have all the parts to build it just sitting around, except for the BBL (and suppressor which I will eventually have and use on other guns also), so I figured I'd look into it. I also have multiple other ARs, from 10.5" SBR's to an 18" SPR type, so I don't really have any other use for the extra parts.
I did consider the 9mm and 300AAC options, but I'm not crazy about sinking all the additional money into those calibers...BBL, bolt, mags, mag block, suppressor, reloading supplies, etc.
Lastly, I have found 3-4 manufacturers that will warranty a can on a rifle that short.
The will to win is common; the will to train to win is much more rare.
A 300BLK is just the barrel. It uses the same bolt and mags.

First off I wanna say thanks to the members here who have contributed at least something to the thread. I have no words for others. It pays to have members like zushwa contribute as I've personally been in his shop and asked him and the boys dumbassed questions and they laughed with me all the way to a solution. Stand up shop. I still plan to buy that mk18 upper when u make it down in a few weeks if you still got it.
The second is I wish to ask the op about which companies he found warranty them that short as I have a pea diablo upper is like to tame a bit.
