Looking to trade car audio for guns

Looking to expand my gun collection. Open to lots of different options, precision 22lr, CZ etc. any semi auto 762 or 556 rifle.
Antique handguns, large calibre 300win mag, prc etc

I buy, sell and install car audio systems as a hobby and have a great used system I would trade for a gun
It consists of a Kenwood KDC-X303 Bluetooth deck. (Retail is over $200) DC audio Level 3 15” sub in box (sub doesn’t look pretty but works good and have whole new recone kit I could install or give with if you want it to be brand new. New is well over $450CAD just for the sub. And a clarion 850rms amp. Could also throw in a full brand new Amp wiring kit. Used value on this system is probably around $600+ pretty easily.
If you’re interested but have something worth more I could add install or add cash to make up the difference
Thanks
