Has it been headspaced?
If so, then have no fear!
The only other thing that can go wrong is that it short cycles due to not enough gas or too much friction.
If it's a new DSA gun, you might want to take some 300 grit wet dry with you to polish any burrs off the bottoms of the feed rails if your brass isn't feeding well and is getting scratched up. This is pretty common on the new DSAs.
Have you done a piston drop test yet? UNLOAD, disassemble, remove bolt/carrier, remove spring from gas piston, check to see if piston will drop back and forth freely in the gas tube? If not this can cause bent or bound pistons and act like a gas problem.
make sure gas plug is in auto position.
crank the gas adjustment screw all the way closed against gas block, then rotate back out half a turn for starters.
If using metal handguards, bring an oven mitt if you take a lot of ammo.
