I switched to a borrowed harris on day 2 and just liked it better. Easier to deploy and easier to unlock the cant. Otherwise, both seem just as stable to me.
Yeah, not too hard, just easier without a crimp. But, crimps only need to be removed once, so no biggie.
I forgot to mention, everyone gets sent home with at least a little magpul gear. I came home with a bit more because I scored in the top at a few of the friendly competitions we had.
