The handguard cross bolts are supposed to clear the slots in the barrel nut. However, the cross bolt holes of the handguard are misaligned such that the cross bolts are forced to partially thread the barrel nut.

Yes, the handguard is not aligned with the upper receiver and the Picatinny rail fails to meet the tolerances of MIL-STD-1913.

The gas valve spring can fall out if improperly installed while under the handguard. It easily falls off when the handguard is disassembled. Removing the spring shouldn't cause any issues with the operation of the rifle, but why add a part that easily falls out. You can simply pinch the spring to tighen the fit on the gas valve to properly secure the spring.

Thank you for your valuable insight. Forgive me for my ignorance, I am not the most mechanically inclined person, but from what I understand the bolts slightly hit the castle nut which is not good. How big of a problem is this for operation? Will the threads on the bolts wear out if repeatedly unthreaded or does this have any other implications?

Yes, the threading in the aluminum handguard will likely wear out first as the steel cross bolts must be removed to clean the gas system. The cross bolts contacting the barrel nut may cause point-of-impact shift when loading the handguard on barriers or a bipod.
