How is flipping the gun over in one direction "practical"? It just adds another step to the reload, making it much longer. Plus, bullpup weapons simply aren't as intimidating as a normal long gun like an AR15.
You have more barrel length in the gun at a smaller size, do you even know anything about bullups?
Literally you're getting rifle length accuracy from a barrel into a carbine length whole gun.

And taking longer to reload? If you acclimate yourself to the gun, you can reload it just as fast as a normal AR platform. There is no extra step. Its the same process as a front loading weapon, just release the loving mag lmao.
