What size gas block do I need RRA Med length upper
I just ordered this upper Saturday and I want to change the gas block to a single rail.I don't want to just assume it is a .750 though. I won't be able to call RRA till Friday so I am hoping someone here knows the proper size.

On some side notes this is my first time posting on this forms the only other firearms form I am active on is the unofficial P-64 forum but this seemed like a much better place to ask. Also, I just got done putting my first lower together and its going to be a long couple of days till I get my upper :)
Thanks for the reply. I measured it when I received it though. I order a low profile gas block from del-ton. I should have know better they still haven't shipped it. The same day I order a new stock, grip, lower parts kit, rail covers, mbus sights and a flash light from couple different stores. My gas block is the only thing I didn't receive last week.
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:
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 ;)
I wish i would have seen that sight before. I didn't even notice that not all gas blocks would cover both pin spots on the barrel when removing a standard sight until they pointed out that one did. Now I need to get another gas blocks and figures mine got shipped today ;-). Maybe I can get a clamp on bayonet lug that will cover that.
Think this would be wide enough to cover it? Don't really need a bayonet lug but cheaper then buying a gas block.
