Why is this the ONLY 10.5" upper with this really amazing looking handguard and also the ONLY 10.5" upper that has a phosphate barrel instead of nitride? I would gladly pay a bit more for something with both this handguard and a nitride barrel, but I'm not super motivated to buy a complete upper and then immediately swap barrels.

BEST ANSWER: Just adding that it would be ideal to be able to buy this beautiful rail separately as well...
Can you ship an AR pistol upper receiver to California?

I recommend this upper, I do wish that the handguard was bigger sense it does get warm real fast.

Very nice
I really like the handguard with the smooth area on top, it does not chew up my hand. I wish it had a nitride barrel for durability and to match the finish on the handguard. 100 rounds so far and it was 100% reliable with a H3 buffer. The chamber is on the snug side but no problems so far.

Excellent Value
I built an SBR with this upper and am impressed. It has functioned flawlessly for about 750 rounds and is remarkably accurate with inexpensive XM193. The muzzle device makes shooting bearable for the shooter.

Terrific design. I like these new slimmer M-Lok rails and the anti-rotation tabs.

I did remove the cross bolts and applied Loctite 242 to the threads as a preventive measure. Not necessarily needed, but cheap insurance for bolts that I don’t particularly want to lose.
