Feed ramp was off - Rival Arms Glock 43 Precision Threaded Drop-in Barrel

With this barrel i got multiple failure to feeds per magazine. The rounds would always go nose up into the barrel hood. That was with fmj and defensive ammo. The issues instantly resolved when i put the oem barrel back in.

The finish on these barrels are pretty nice, but who cares if they won't feed.

Don't buy these. They're too expensive to ever have the kind of feeding issues i had.
