Thanks for the replies. Maybe I should shop around before I decide.
I've got one which I bought a few years ago somewhere in the $900's. I picked it up from a Walmart before all of the big panic. My are that you'd be hard pressed to find one that looks better and has this fit and finish for the price point.
I have had zero issues with mine. I really love everything about it and it has been 100% for me. I have shot a mix of brass and steel case ammo through it and it doesn't hiccup on any of it.
I too have heard some of the parts for the Sig are not interchangeable with some AR parts, but I haven't had an issue on anything to date. I've only upgraded a few minor things.
I love Sig and this has lived up to my expectations of them...
First time out a year or two ago...
I really like they way they do their ambi mag release
This is a really nice feature to me as well...
