IIRC, the "Legacy" series was Daisy's last attempt to capture a portion of the RF "kid's" rifle market segment. They showed some unique and, in some cases, usefull design features ie: butt stock adjustable for LOP without tools. At least the plastic-stocked BA that I purchased to teach my then-SO's young son did. Also had a Ruger 10/22-esque rotary mag, I believe. They were discontinued after a relatively short time after disappointing sales volumes.
There were three basic models, IIRC: a SS bolt action, a magazine-fed repeater BA, and a semi-auto. I believe that there was a wood stock & forend option available at extra cost.
While the light weight and handy size were 'pluses', I was somewhat unimpressed with the quality of materials used to take advantage of streamlined manufacturing methods in order to keep costs low. The plastic stock wasn't particularly rugged, and the Zamak receiver et al gave me some serious misgivings as to its potential longevity in extended use. The finish on the metal was some sort of matte black paint, and was not very durable.
On the positive side, it was quite inexpensive and surprisingly accurate for its modest price. It was also easy to clean and very reliable in function. My longevity concerns were never really tested IMO, as less than 1,000 rds went through it while it was in my possession.
The only possible source for parts that I can think of for these now-obsolete little rifles would be Numrich (The Gun Parts Corp). Haven't had a current catalog in several years, but contact info I have is: (914) 679-2417; Fax: (914) 679-5849. Be aware that these are severaL years old and may have changed. A Google might turn up a web site.
Hope this is of some help.
