I ordered this upper minus BCG from PSA. It came with the float tube, and a highly regarded FN barrel for $299 delivered. It's an A2 profile with mid-length gas system, 1/7 twist, cold hammer forged and double chrome-lined. Should be fun. Just got her painted up, next stop the range. Shane

I tried a different color scheme than I usually do. Used some Rustoleum colors from Walmart. I like the way it turned out. Started with a sage green base coat, Then accents with brown and tan, sprayed through some dry grass.

Took this rig out to zero yesterday.
Was getting odd results, 1 moa lateral spread, and 4 moa vertical spread.
When I got home I went over it in detail and found my trouble. I had installed a YHM M-Lok front swivel in the bottom of the float tube. I didn't pay close attention and had inadvertently ran the M-Lok hard against the bottom of the gas block, pushing the top of the gas block into the top of the float tube.
Not a lot of clearance on these low profile tubes. I relocated the front swivel back a notch, and got off the gas block. Everything is floating again.
Will get back out and re-zero soon, and get some chrono numbers.

I've got three loads on hand.
Yesterday was 77gr Nosler over 24.0 gr W748
Also have 53gr VMax over 24 gr XTerminator, and some milsurp Green Tip.

MM - if that Vmax load doesn't shoot as well as you'd like, try bumping up the powder charge more. I've used a bunch of XTerminator for 50-55gr bullets and almost always found that it shot best and was most consistent at or near max; ~2-2.5 gr higher than your 24gr charge. Ambient temps here are a little lower than you might have though so take that into account; 90 F is a pretty warm day for us.

I loaded up a bunch for prairie dog shooting.

Got some velocity data today on a few loads. I used a Magnetospeed for velocity data. 5-shot averages. Accuracy data was 5-shots without the chrono attached. - M855 'green tip' (PMC) - 2860 fps, 2 moa accuracy - 53gr VMax/24gr XTerm - 2870 fps, 1.5 moa accuracy - 77gr Nosler/24gr W748 - 2605 fps, 4 moa accuracy I can see where the 53 VMax wants more powder, should be up around 3000 fps or so I believe.

Shane,
How do you like the Magnetospeed?

I like the Magnetospeed a lot. Small to pack, easy to set up, not light dependent. No lining up tripods. I have seen a rail adaptor out there for mounting it to semiauto pistol accessory rails.
The only con I can think of is it may shift your POI on a rifle.

I have the magnetospeed and I love it. I sold my prochrono and never looked back. I always get good data, in any condition. Very useful for my high end airguns that I usually shoot indoors.

MM, to follow up on my previous comment, from a 16" AR I loaded up to 3000 fps with 55gr SP bullets and XTerminator, and up to 3180 with 50gr Vmax, with best accuracy at those top loads. I don't have a velocity for the 53 gr but one could make some educated guesses.
The 77gr Nosler load sounds disappointing. I had difficulty getting that one to shoot well too until I tried Benchmark; 23.5gr shot well with an S&B SR primer. Velocity should be ~2650 fps in your rifle. 8208 XBR seems to give pretty much the same results for the same powder charges so either one will work if you have them. ( I have been suspecting they may be the same powder with just lot to lot variations between them).

The Nosler 77 gr has been lackluster in other AR's, as well as the Ruger American Predator boltgun.
The 75gr Hornady BTHP shoots well in the other rifles, I need to load up a few to try in this one.
