I have an AR-7 that I bought new and never fired. It does have some marks on the stock from bouncing around under the back seat of the car for a while, but other than that, it should be indistinguishable from brand new. It looks like the going rate is $250 for NIB, so I would go $200 FTF near downtown Houston. Or I would ship it to your house (at cost) if you give me a copy of your TXDL to verify residence. Cash, USPS money order, or discreet online payment. I am not active here, but have references out the wazoo. I'll get a photo if you are interested. Thanks.
There is an ar7 at a local shop in Hunt county for $125. Its obviously not new, but in pretty decent condition. He also has a papoose for $169 and Ruger 10/22 for $179 all used. Was actually thinking of picking up the survival rifle for the kids to shoot. Good luck finding what you're looking for.
