As long as Biden is President, prices will remain high.
How high is a different story.
Go to Gunbroker, if you have membership, and check prices they actually sold for, not listed but sold.
I was/may going to sell some more guns but thought -- just because they list that high does not mean they are selling -- so I did that and found I can make a nice profit on some of my firearms.
There is no crystal ball to find the peak time, but right now, if you find a buyer, is a good time.
Put a high reserve on it, and list it to see what happens, if you decide that is a rare gun you can never replace.
