Great for lightweight builds. - Strike Industries Ultra Light Pivot/Takedown Pins

I'm not sure why anyone would opt for aluminum pins like this if weight wasn't a factor...but then again, weight often IS a factor. If your AR rides your pack or shoulder more often than a sandbag, it shouldn't weigh you down like a sandbag. I know what you're thinking; with clever writing like that, this can't possibly be a real review from a real customer. But it is. You're welcome.

I have used these pins in a couple of lightweight builds, and even though they're small parts, every gram counts. So, as a part of a system-wide weight reduction strategy, I think these pins are great. Plus, it's one less steel part to corrode. Fit and finish are excellent as you'd expect from this company.

As far as durability, the way that AR upper and lower receivers mate prevents much range of motion between them, other than the intended pivoting for bolt access. Meaning, there's not much leverage to challenge the pins' strength. Time will tell, but I'll be shocked if this part fails due to wear.
