Sunray,
The "Husky" and "H-5000" were a Tradewinds creature and existed as two different rifles;
The "Husky H-5000" made from a 1640 action with a 560mm barrel and the Krico actioned ones. Already in the late '60s Tradewinds bought rifles from Krico (the M/600 short action - offered in 222 Rem, 222 Rem Mag, 243 Win, 308 Win, 22-250 Rem and 223 Rem) and later had a run made with the M/700 (standard action) wich they named the Husky 5000 series.... these guys liked confusion.
On the other hand, from '65 to '70 HVA bought some M/600 but only chambered in 222 Rem. These were named m/2001 and 2002. This was to compete against the Sako Vixen.
Bullseye61,
You are talking about the bolt stop / ejector blade right?
If so, your easiest way to find one will be to talk to Trade Ex, but will have to strip a receiver. But these are not so hard to fabricate, all you need is a Dremel and a set of good hand files.
