Classic RT vs ULE help

[jbogle4422]

Can anyone tell me the real difference between the Classic RT vs the ULE with XValve?
Other than the obvious weight reduction and center feed in the ULE's, is there a real difference?
High input pressure and sweet spot the trigger, will machine gun on both.

I finally got a hold of 2 classic, clean, and unmolested RT's, but I'm trying to decide if a ULE build is in my future.

Thanks

performance wise they are very similar. I don't think the classic rt's are milled for the 2nd oring, which means you can't use the ult. The banjo hole will have to be drilled out on any frame you decide to swap over.

Thanks for the info.

I'm not looking to do anything with my classic RT's except for a lv 10 bolt. Besides that, I plan on keeping them as they are.
I'm just trying to decide if I need to do ULE build or not.
From what I have read, the only advantage is the weight, use of AC threaded barrels, and just the overall look of the mag.
