I am thinking about geting a RRA national match for matches at my local range but it's Chambered for .223 wylde.

so what in the world is .223 wylde???

It's a compromise between the 5.56mm chamber and the .223 chamber. From my reading it lets you safely shoot mil surplus 5.56 or .223 while giving you a little more accuracy than the 5.56mm chamber.

The wylde is a short thoated chambering for the .223. The reason for this is it sets the bullet closer to the lands when it chambers. Less jump = more accuracy. The Wylde chamber really comes into play when you are launching 80 grainers that are sized longer than 2.500 OAL. I think the Wylde is pretty standard on RRA rifles now, and they make a GREAT rifle. I have not heard about any problems with the wylde chamberings and if you are going to be shooting long range, over 500 yards, the wylde will be an advantage. Of course you have to look at the twist rate too.

A good article on this was written by Glen Zediker. He is a great expert in AR's

The wylde chamber is a compromise between the 5.56 and the .223. Most RRA rifles are a 1-9 twist. Mine is fabulous, I couldnt ask for a better rifle. Im currently building a .204 that will have a RRA lower and 2 stage trigger.

what is considered a good twist rate for a AR

That depends on what weight bullets you plan on shooting.

In a nutshell:

If you don't handload, 1-9" is just fine.

If you do, and want to shoot heavier than 75 gr. bullets, go for a 1-8" or 1-7"

If you get the RRA NM rifle, it will come with a SS 1/8 twist Wilson air-gaged barrel. If you're going to shoot in matches, that's the one you want. The barrel is free floated, 2 stage trigger and match sights. RRA is by far the best off the shelf NM service rifle you can get. Just make sure you get a good Turner sling and a balance weight for the butt stock. It will help balance the rifle for offhand.
