I have never worked with it, but I thought it was more Hornet/.218 Bee category.

I can scarcely imagine the look on peoples' faces when the pleasant looking old guy and the fuzzy dog go ambling past, with a PS90 slung on. That would pucker the Missoula latte crowd.

But back to our regularly scheduled programming...I am not an AR15 wonk. I do not know all the tinker toys that are out there that people are using to build them up. I posted this in the AR forum because I wanted to learn from people with more experience how light one could feasibly go in that platform.

We are on page 8 of the thread, and I really do not have a much better sense of an answer to that straightforward question than I did before, except that it is possible to go so light as to become questionable in terms of function. It is clear that Big Stick likes the Kimber Montana, but I think we learned that about 15,000 posts ago.
