We already have a ton of non-restricted rimfire rifles available.I say keep fighting it. Rimfires are selling like hot cakes. I was bummed that I couldn't do a NR shorty.
I'd love to build something small I can shoot for kicks out back, instead of having to go to the range to shoot it.
These guys are extremely busy.
Time spent on rimfires is time NOT spent on Modern Sporter receivers that everyone needs.
