Here is the latest video from
AV Guns running an POF-USA 18" SPR full auto. Also testing the new POF Precision Sniper Stock. Precision was not the goal of this video as you can see. The stock did perform well, was comfortable and took the beating. We ran 1,050 rounds (7) Armatac 150 round drums through the rifle without cleaning or lube. All Armatac drums were dumped. No slow fire here. We loaded a mixed variety of ammo. Some drums were Wolf, XM193 and M855. All ammunition functioned flawlessly through this 18" SPR upper. Stay tuned for more extensive torture tests of different length POF rifles with faster reloads and more volume of fire. Enjoy the video.

I can tell which bullets were XM193. They're the ones with the huge fireball.
Why don't you put a tarp down to make brass pickup easier?
On string three (where you started with two singles), why does the ROF start out slow and increase?

I didn't think we would look tacticool enough if we laid down on a tarp.

Doc,
You have a keen eye. Not many people notice that. It is caused by the pressure of the spring in the drum and only noticeable on full auto. Have you ever tried to load a topped off 30 round mag in an AR with the bolt closed? Sometimes it doesn't seat and it takes some force or a hard tap. When you downgrade that mag to 28 rounds or so, it is much easier to seat the mag. Same thing with the drum. As the pressure is reduced by firing off more rounds, the bolt carrier moves more freely and faster. Good catch.
