The FrankenMP5 will be making a brief appearance with tracer rounds at FR on the 28th.
Got the new bits and installed it. Seems to work fine. First shot does not penetrate a can still but the second one right after it does go through both sides. I'll chalk it up to being a new spring. Will have to put it up against a chrony to get a true idea what it's shoot but I'm happy with where it is being a primary CQB weapon. Solid, heavy and crispy.
