Dave-
I bought a CLE 22RF upper this fall, and have been having a lot of fun practicing with it. Mine is in service rifle configuration, with a float tube so I can sling up with it, and has 1/4 min. sights. Its Douglas SS 1~16 twist barrel is a tackdriver, even at 100yds. with Eley Match Xtra ammo. At 50yds, I use much less expensive($112/5M+freight)Aguila SE that John Feamster wrote about in the Nov. issue of Precision Shooting. My upper doesn't shoot it nearly as good as John's AS upper does, but RF barrels can be very picky about what ammo they like. Mine does shoot very well with SK Std. Plus, which runs $180/5M. I really like being able to shoot as many RF sitting & prone strings as I want without burning up a valuable Krieger match barrel, and it's also great for offhand practice. Frank supplies RF uppers with a modified M261 conversion unit, two magazines, and a neat single loading device that makes it easy to practice prone SF. I called to ask about getting one on a Friday, and because they had one ready to go, I received it on the following Friday. Price isn't cheap, at $950, but it beats the Victor Arms V22 I had before. Firearms International has parts for the M261 unit, and Frank is working towards getting a supply of spare magazines manufactured.
