I bought a Guardian .22 and started the tax stamp wait in January. Maybe I'll get mine in time for my June birthday. So, you like the Guardian? I don't hear many reports on them. Just got notified today that the gunsmith has finished threading the barrel on my 10/22. Already have a threaded 22/45 that I picked up a couple of months ago.
If the Guardian .22 works well, then I'm going to order a Guardian 9 for my G17 and for the .300 Blackout that I recently acquired.
