Personally, if you have a nice collection of firearms, I’d spend it on ammo (when available) and hi-cap mags (when available). $1,000 isn’t going to go very far with the hugely-inflated prices for firearms/ammo/mags, these days.
Invest in bass and lead and hi-cap mags. I did over the past 11yrs, and I’m well-stocked.
