I'm planning on adding some kind of optics later but 1st a stock. I'm really open to buttstock suggestions, so fire away.

Looks like the Gen II might work as well and is less $$$
Not saying there is anything wrong with the UBR it just seems to contradict the purpose of a SBR. Your Sig is heavy to start with and if you are not careful you will end up with an 11 pound rifle before you plug in a magazine. The UBR weighs 3 times what a BCM or B5 stock weighs.
