I have a Feather in 45 ACP. I like it, it is light and fun to shoot.
I am selling it though, I want to deck out a couple 10/22s for bench rest shooting and build up an AR upper. I have it listed in the equipment exchange. I have pictures of it in one of my AR15.com photo albums. Click on "my Profile" icon and look in the for sale album. There is a Big gun show in about 2 weeks, I am planning on taking it there, if it dont sell there, it goes on Gunbroker.
If I was going to keep it, I would put a front foregrip on it, and consider geting a red dot for it. It now has a 4x scope on it....maybe even pic up the adapter to allow me to put a AR style stock on it, either the CAR or the A2, since i have an extra one of each laying around here.
