Haven't seen any reviews online, but someone somewhere must be using one of these.

If anyone knows anything real world about them please post here.

Thanks!

Wow! They must be really good.....

Everyone is speechless...!

Well, I got a chance to shoot mine today.

25 yards outdoors (not much wind) at my clubs Pistol House, cheap Simmons on 3X, sketchy front rest & no back rest. First 5 shots were with RWS subsonic which produced a group of 3/16".

Gun is a put-together (by someone else) with no upgrades beyond a nice BX trigger. No bedding either.
And I shot that group close to rapid fire - I was really just using the gooey subsonics to get some lube into the bore. Every time the crosshair dropped back to the bullseye I let another round go.

I was introducing someone to shooting today so I had very little trigger time. I did run a group with RWS HV HP which I really screwed up, and one with Aguila SE SV which looked like the subsonic group minus the 1 called flyer.

So, my 1 experience with that Brownells (Azimuth Technologies) barrel is pretty bleeping good.

What barrel length and contour does it have?

16" sporter contour. It has an odd, very slight OD reduction starting maybe 6-7 inches short of the muzzle.

Threaded BTW, and it looked weird to me being so short, so I put a $15 ebay muzzle brake on it just to get some length.

Ill post a pic and set up a link.

Also, it has a counterbore at the crown, and when I scrubbed the barrel with CLP & a brass brush, the finish came off the counterbore, and I assume the bore as well.
The barrel finish wasn't affected by CLP on the outside.

What sort of chamber does it have, regular or Bentz?

I don't know, but they call it a "Sport" chamber with a capital S (per the advertising people I'm sure).
I don't think it relates to any sort of standard.
