Problems with it
It doesn't have a delta ring.
Flash hider looks disgusting.
The handguard isn't complete.
Magazine isn't scaled correctly, it should fit inside the magwell.
The ironsight or whatever the hell that is that's standing up near the front of the handguard looks incredibly out of place.
There are a bunch of little bits on the receiver that also look out of place.
Charging handle is made incorrectly.
Stock looks fugly but, that's not really a problem.
I'd need another angle of the gun but, I'm guessing you didn't add a bolt release.
