What are the big watchouts or decisions one must make? Robert the Texan and others have built their own here. I'm just in research mode
What barrel do you go for?
What mfg make good barrels ?
Adjustable gas blocks for AR10's?
What rail or who makes AR10 rails ?

Hey PB,
You are probably on the right track with the Noveske upper Mega lower as they both have the same upper receiver/lower receiver angle cut. Same as the SR25 and LMT MWS. The big question will be fit. So make sure you check fitment with pivot pin and take down pins installed.
The Mega Lowe will come with bolt catch installed (using a threaded hex bolt with is so much nicer than hammering a pin in, and if you get the Mega Ambi lower it will have the ambi bolt catch. No real gotchas with the LPK, , just remove the bolt catch before you install mag catch/button.
I’ve ran mine both with rifle gas and A5 system. My current AR-10 uses the UBR Gen 2 stock which uses the same length buffer as the A5.
So as far as pitfalls. Realizing that Noveske, LMT, KAC, Mega and LaRue are compatible (for the most part) and Aero, DPMS, PSA, CMT are the other standard. You’ll need to make sure that your upper and lower receiver profiles match (DPMS High and DPMS Low). This will not impact your Noveske upper.
Gas blocks:
On my Aero 308 I ran an adjustable gas block. My MWS does not. I prefer standard GB, sure you can tweak out some recoil impulse, but you are putting a lot more strain on that GB than an AR-15. Not sure if that’s why my first adjustable GB failed on me. Bottom line for me? Adjustable gas blocks introduce another point of failure that a mil spec GB does not have, so I don’t run any adjustable GB on any rifle I own.
Rails... yes as mentioned not the same selection as AR-15, but CMT, SLR, Mega all have really sharp options along with the the other mainstays - Troy, Midwest, Noveske and even your favorite - KAC. Although when I looked st the price I literally laughed and muttered words my mom would be ashamed to hear me speak. But it was a nice looking rail.
