Feather Rifles is still in business (see the link above). I purchased a new RAV 45 ACP rifle from them 5-6 weeks ago. They haven't updated their web site in ages, so it's probably best to just call them; they have phone numbers posted on their web site. They're a very small division of some company called AWI, and there isn't always someone there to answer the phone, but they'll get back to you. They did some nice trigger work on my Feather Industries AT-22 (Feather Industries was the previous maker of these rifles) this past winter.
They should update their web site. They have a neat new feature for their RAV 45: it is now designed to take Glock mags, rather than hard-to-find Uzi mags. I am always amazed at how accurate both of my Feather rifles are. The AT-22 does jam occasionally, but generally works pretty well with high velocity .22LR. The RAV 45 is rock solid. -TB
