Great gun. I was busting water bottles at a 100 yards after three shots. I added a quad rail and a pistol grip before taking it out. Great setup. Simple, efficient, and accurate. It took a while to get it due to some processing delays but all in all I'm satisfied.

This was my third...
This was my third purchase from buds and by far my favorite. The weapon performs flawlessly every time I squeeze the trigger. Sig deserves some major respect for building a weapon that performs as well as my buddys bcm. I have added a six power scope, a larger latch on the charging handle and a muculek compensator. Thanks bud!
