If all works well I think your choice of accessories is well chosen. Good luck and give us a range report before and after your additions.
Glad the 2nd one is a good one...my 2nd one is a little better than the 1st one with regard to abnormal wear on the mag tube, but still has the occasional shell elevator jam issues and the sight windage adjustment annoys the crap out of me.
