Let's say you had to run a collapsing stock with an AR SBR that had a rail mount 203. Which make/model would you go with? I'm considering the magpul ubr gen 2, when it comes out. Durable enough?

yes, def an awesome stock and heavy enough to balance out the 203's frontweight.

The CAR stock and the M4 stock have been used with military M203s for a long time now.  Any quality stock/receiver extension should be fine.

Yeah it doesn't have to be anything special. I have a LMT SOPMOD on mine. What DOES need to be special is your rail system. It has to be designed to handle M203 recoil and transfer stress correctly through the barrel nut.

Yeah, standard stock & extension are fine.

I too know what it is like to get that "New Something" and want to but the absolute BEST-EST parts on it !

No need to overthink it - really any stock you are comfortable with on an at least milspec extension should be fine.

Balance?  Ugh.  Good luck with that one!!  

Short of a Space Gun Stock with weights ADDED to it, I don't think it will balance very well~!

I should be OK on the rail, it's a Mega Machine MTS (monolithic 7075 goodness). I've carried a 203 in the marines. They're definitely front heavy. I'm gonna try to help the balance (not fix, just help!) by using a short lw bbl (DD CHF 11.5") and a relatively heavy stock, which is one reason I was thinking or running the ubr 2.0....
