nicely done. sweet.

Barrel, bolt,handguard is the same as i've wanted.

Would be interested in chrono numbers and how she shoots.  

do you have  access to a range with some distance, that would be a good time.

My initial chrono numbers were quite a bit lower than what I expected (2600-2625 fps with factory AMAX) but the more I researched this seems fairly common with the first 100-150 rounds of ANY new barrel.  Now I'm at around 150 rounds shot and I plan on chronographing any new loads.  I'll post these results up when I have them.  I do have occasional access to a friends farm field when him or the neighbors aren't out working.  About three weeks ago I had it hitting pretty consistently at 500 yards with factory 123 AMAX.

2600-2625fps is well within the norm.  With factory 123gr AMAX, you'll be anywhere from the high 2500s to high 2600s (2580-2680fps).

Nice fire stick.  Did you do any accuracy work on the upper assembly, like barrel bedding?

My original hope was 2650 with factory 123 AMAX.

The only accuracy work I did on the upper was to true the face receiver.  I'm not sure if it would do anything, but a buddy had the stuff and talked me into it.

Especially on longer barrels, it helps to bed them.
