Send it back!!!
I had some initial feed ramp issues with my Bushy, and I am talking about FTF like every other round. It was bad. I cleaned it and changed ammo, and the problem still persisted.
I explained it to Bushy and they emailed me an overnight UPS label and I had it back in a week.
It functions 100% now.
They added a D fender looking thing to the extractor, polished the ramps, and kinda cut in m4 looking feed ramps.
I am a happy camper at nearly 500 rounds fired without a failure. I even did a 120 round rapid fire stress test.
It was kinda hot to handle (thank god I put on para cord on the handguards)
I love it, I really really love it.
I just got a nice, bright reflex scope and I have some 68-77 grain "I mean business" ammo that WILL fragment out of the 7.5 inch barrel.
You have a pretty mean PDW there.
