Welcome to the Colorado AR-15 Shooters Club Discussion Forums.
DOH!
I just fixed a similar issue with a home build a couple of weeks ago.
The owner had inadvertently installed the gas tube upside down.
They don't cycle so goodly iffins one does that!

Well it was a 20" so the misalignment was a bit subtle
He didn't bend the tube but it looked funky.

I had a similar problem with one of mine on a rifle length upper. I had it misaligned just a tiny bit and it was enough to prevent the gun from cycling on 55 grain .223 but it would cycle on 62 grain m855. It is hard to tell if they are off just a little because there is not a sight post sticking up to reference off of and the allen screws to tighten it on do not index like pinned gas blocks.
Sorry to keep you all waiting on this. I am using a gas tube that is not new (1000 rounds) it was cleaned every 250 or so and does not appear obstructed. The gas block is and was properly mounted. All holes lined up. Gas tube oriented properly.
Because I am studying for the bar I have not been able to shoot it recently since I broke it down.
The dams block operated the gun perfectly, the Troy failed to cycle. Went from Troy to DBMS and back to Troy.

After trying a number of different combinations, I switched out the flat-wire spring for a standard spring and she runs like a dream. Thanks for the input guys.
