Was this a good deal?

That's what I figured. I didn't buy much brass yet for reloading and I have been using a 10 round PMAG for my first Grendel loaded with only 3 rounds to avoid mag bulge. My first Grendel is 16" and I did not see much point in getting another unless the barrel length increase was significant.

I am not sure if I will get it apart if I want to reconfigure since AA apparently Loctites everything together in a solid mass.
