How short of a shorty?

I'm trying to decide between a 10.5,11.5 or a 7.5 (already have a 16). I really like the looks of the 7.5 but know the ballistics of the longer barrels are better, though bullet fragmentation is not an issue for me. Am I better off the building a 10 or 11 with my VIS1 and save the 7.5 for a 9mm build later?
 
I've built three 7"ARs, and owned a DLASK built MINI Moose.
They are LOUD and the flash is quite impressive ...
To the point it is very distracting to your range neighbors,
and they WILL complain.

5.56 NATO ammo out of one of my 7" barreled builds chronoed at about 900 fps less than the same load from a 16 " . The shot to shot velocity variation with the 7" was much more significant than with a 16". For paper punching, this doesn't really matter, but for XRATED Zombi Mutants, you may want more punch.

I currently have a 10.5" LMT, and find it balances perfect for fast close paper punching, and it is significantly quieter than the 7". Still a bit of a flame thrower with BALL ammo.

I think my previous build with a 14.5" is probably the ideal length, and though I find my 16" LAR 6.8 feels a bit longer than I am used to, it still balances well. The longer barrel does improve the 6.8 [ and the 5.56 ] threshold for reliable expansion/fragmentation ... if that is mission critical to your mutant zombi hunting role.

just one person's opinion ...

Any idea where one could get an LMT 10.5, Questar doesn't carry them. Besides a custom build the only ones I've seen are RRA and the ones from Fab. Noveske would also be nice but no body sells them here.
 
I bought a NEW 10.5" LMT upper two weeks ago from Dlask.
EXPENSIVE ....
especially considering that I usually build a complete AR 15 for less than what I paid for just the LMT upper.

At that time, Joe said he might have one more LMT 10.5" upper left.
 
Questar shows stripped LMT 10.5" uppers in stock. You could also have a look at Armseast they still had one of their 10.3" N8 uppers left after I bought mine.

Saw one in the EE today for a good price...surprised it hasn't gone yet. I've got one and I find it way handier than the 14.5" AR15 I had before.
 
Thanks guys but just to make it clear it's the barrel and gas system I'm looking for as I already have Vltor upper for the build.

I'm going to give Walt a call today.
