If you spend much time around the guys who really, really know their craft, and who truly live this stuff, you tend to find that they are very soft-spoken and modest -- almost to the extreme. To my mind, that is a model worthy of emulation

No doubt about it. I'm pretty sure it's gassed close to my FN 10.5 based on internet searching. But we'll run some buffers in it and maybe shoot some groups and stuff.

I think I remember reading somewhere that salt residue from the slat bath can deposit between the threads of the barrel extension when treatment occurs with the barrel extension attached, later leading in corrosion. Is this a concern you have addressed or a non-issue?

Got the barrel today. It looks pretty good. A few initial observations are:
1. The port is about .078"... Too rich for me, but I hope a heavy buffer can rein it in.
2. The port is obviously reamed post QPQ, but Aero already posted that fact, and
3. The taper pins are reamed a little deep into the barrel. In the pic, you can see that the pin holes are so deep into the meat of the barrel that they are enclosed. Not necessarily the end of the world, but not quite the ideal 50% of the pin diameter that would be ideal. On a 10.5 blaster, this shouldn't be a big deal. The pins come partially driven so that you can easily remove them to install your barrel nut.

thats interesting Mark. Thanks for sharing.
I'm surprised they are so deep, but for the price and the gas port size (.007" isn't far off) I might grab one of the FSB models
Why do the loudest do the least?
I put this thing in one of those $49 Bushmaster Flat tops from Brownells. Those are pretty nice uppers.
I used the delta ring and handguard cap, and it'll have a carry handle on it to get started.

I have been vary happy with my barrel. It is a 10.5". Didn't check the gas port with a micrometer but it runs just fine with an H2 buffer and carbine spring. I don't run the A5 stuff. Most notably, I am impressed with the accuracy and consistency.
