Not affiliated with these guys at all, except as a very happy return customer, and this isn't the first time I've recommended them, but I highly recommend these guys:PK Firearms.com
The main reason being, IF it's on their web site, they have it IN STOCK, so you don't end up waiting for 2-8 weeks. Their prices are pretty competitive, their customer service is excellent, so is their overall service. I receive most orders in a 3-5 days from date of order, so no complaints from me. Try them out next time you need something. You won't be sorry.
By the way, nice looking SUR you got there
