I've never sold a gun that I didn't regret later.
Having said that, I think Dave, spec ops is right. A gun ban or registration isn't going to pass. A private sale ban probably will pass.
I think the market price is as high as its going to get right now if it already hasn't started coming down as the likely hood of a gun ban seems to be decreasing. So if you really want to sell it now is as good a time as ever.
As far as value I don't really know, a pre ban Norinco with one 30 Rnd clip is worth about $1100-1500 in Houston right now. What variant you may have I don't know the value of at all tho.
Edit, I called my gun dealer buddy and he said the pre ban Norinco is around $1400 at the moment.
I have no idea what components you have when saying American made or built but the Norinco should give you a point of reference anyway.
There is something to be said for having Un-papered (non 4473'ed) guns in the event a universal background check (private sale ban) passes, which I personally think probably will.
I think any fed legislation that passes will grandfather in and not require registration of any existing guns. Current fed law specifically forbids registration by the Feds of anything but NFA items. But a 4473'ed gun is easily going to be registerable since the BATF can't be trusted not to use those forms they failed to destroy like the law says they are supposed to. It's a back door to future registration, and even if they do destroy the forms like they are supposed to they can simply confiscate all the dealer logs which are required to he stored for 20 years and use those for a registration effort.
I would not expect ANY state gun legislation to even he introduced in Texas unless its something that tries to offset or counteract new fed laws.
Texas constitution forbids cities from passing gun regs so that's not a worry in your Republic of Austin even with all the hairy legged tree hugging liberals you have on city council.
