Good luck with that, everything on gunbroker is double to triple its normal price. Same thing that happened back when the idiot was about to get in office the first time. Things will probably settle down in a couple of months and junk will be cheap again. I have 8 stripped lowers to finish and I can wait.
Probably not a great place to sell it either. The stripped New Frontier lowers are averaging about $80 on gunbroker. Most people are afraid of the polymer lowers so they don't command a lot. I personally like them because you can build a great lightweight carbine to carry in your vehicle without worry of rusting or scratching it up. I had a couple of the Plum Crazy polymer lowers and they worked flawlessly
