I'm shopping around for a 16" midlength barrel with a front sight block. Want 1/7 or 1/8 (I have a bunch of Speer GD 75s and some Hornady 75s that I'll shoot in addition to the standard 55-62g stuff).  

I got a couple Brownells C7/A1 uppers to mess with.  This is going to be a truck and range gun so I'm trying to go fairly cheap.  I've found one (a LW nitride 1/8) at JSE Surplus which looks like a good deal, and one at DSG (nitride 1/7 which looks to be a BA barrel).  

Anywhere else I should look?  

Any other recommendations?  Maybe just go with a carbine length? Seems like more cheap options.

Thanks

Last time I checked BA/Aero had one for around $200

Centurion has a very nice one I'm pretty sure

Spikes tactical

Hardly a rare configuration.

Thanks, I'll check on Spikes.  I've been looking for one of the Aero/BA versions and they are out of stock everywhere, except the DSG version, which seems a bit overpriced...

And yes I realize that this isn't an uncommon configuration, but they seem to be out of stock everywhere I've looked, so I guess my question is: does anyone know of any that are currently available?

If you decide to go full send on it OP you can check out Noveske's N4 barrel.

CDNN Bushmaster closeouts.

Here's a complete FSB CL mid upper (1/9, HB, no BCG/CH) with MOE handguards and YHM Phantom for around $250
