Looking good. But I've a quick question...is your upper a monolithic upper? I ask because of the way you have your scope mounted. It looks like it's mounted half on the upper receiver and half on the top rail of your handguard. If it's a monolithic upper you shouldn't have any problems. If it's a railed free floating handguard, you'll want to move your scope mount back fully onto the upper receiver. If you don't you could have sighting issues because of the flex or movement you'll get out of the handguard when shooting.
