I have a BCA side-charger that I picked up not too long ago when they were running a deal on the upper with a BCG. I stuck a Wylde barrel on it and put it on top of a Ruger lower. Fits almost perfectly....no gap, no rattle. The finish is fine...it's very close to the Ruger. I wasn't sure I'd like a side-charger, but it's fast becoming one of my favorites. I don't have a whole lot of rounds through it (~200), but so far, so good.

The question isn't who is going to let me; it's who is going to stop me.
