I haven't checked in for some time and didn't want to hijack Phil's thread, so here's a new post. I've been thinking about suppressing my 15-22 for some time and got pushed over the edge with the release of the new Silencerco stainless steel 22Sparrow. I ordered one today from Major-Malfunction and can't wait for it to arrive (2-3 weeks). I also got one of the first ones off the line (low SN) - FWIW. I'm setting up an NFA Trust using a VA lawyer and might just SBR my 15-22 at the same time to save one Tax Stamp fee. Let's hope the ATF processes the paperwork quickly!
