Imagine a vertfeed ule RT with a red or blue smear anno AND matching barrel!!
As it's been mentioned TL-AC adapters are certainly an option for those who prefer to use an AC barrel.
As for those who worry about their non-cf tl barrel, as long as it's not stainless, it's VERY easy to drill a small divot for centerfeed. Heck, you can get away with using thicker barrel orings to hold it in place instead. The barrel really won't twist on its own.
Keep this as close to "classic" as possible (minus the weight and vertfeed :D)
... although, it looks like XMT made his decision :(
