There seems to be a little confusion about the upgrade on the 22sparrow. The new core is completely redesigned and is constructed of S/S. The new half pipes are constructed of steel. The new and old half pipes are not going to be interchangeable. The upgrade will be supplied with new steel half pipes. The upgrade is not 5.7x28 capable, the new production 22sparrow is supplied with a steel outer tube and IS 5.7x28 capable. 22Sparrow is a killer can on the .17 hmr, I use it that way all summer. the new one is very, very good on the .17 hmr as well. just a quick note to clear things up, inbetween writing orders!

I love my Gen 1 sparrow. How long will the offer to upgrade to the new SS sparrow be available? I'm getting laid off tomorrow, and won't be able to take advantage of it for, well, until I have another job...

Sucks for me (sort of) but I'm getting my new Gen1 in a few days, after 4 long months of Snook. Hows about a free swap
