Re: Sako 3-n-1 gun 02/09/04 09:49 AM


I talked with Sako personnel last weekend and asked about that new 3-in-1 rimfire. I've bee told, that it should have been secret and that rifle will introduce in SHOT show to very limited group, not for the general public.
Few rifles have been made for testing purposes. Proto series will be made in the summer and zero series will be made in the fall. So it will be 'new in 2005', at least here in Finland. Maybe there in States it will introduce earlier.
It have easy switch barrel idea. Only one hex-screw need to open etc. But I didn't ask, if all three barrels comes with that rilfe at the same time, or should they bought separately.
Let's see how it looks like. Maybe that's the reason to sell my CZ 452 American and buy the domestic rimfire.

Hopefully you understand my not-so-good English.
