While cheap guns have always appealed to budget-minded buyers, I think the current situation may have caused an unexpected shift. From what I have seen at stores and from online sellers, the midrange ($400-$800) guns are the ones that are sold out. The "cheap" guns have gone up in price by $25-$100 depending on model, but they still appear to be available. The guns in the $1200+ price range also seem to always be in stock.
I think that those of us who already liked guns, whether to avoid a price hike or possible legislation, have been purchasing our bucket list guns or the mid-range guns we were always curious about. The first batch of new gun buyers seem to have mainly purchased offerings from well-known manufacturers, which just happened to be the mid-range guns.
I don't think many current first time buyers are intentionally buying cheap guns. I think they would be perfectly willing to buy a $500-$600 gun from one of the few brands they have heard of, but those guns just aren't available. These buyers just want to leave the shop with a reliable firearm, and are unwilling or unable to buy a $1500 race gun.
If the cheaper brands are reasonably reliable, I think there is a good chance that this market will create a lot of new SAR and Canik fans. It shouldn't be too difficult to appear reliable because the current buyers won't be able to purchase more than about 100 rounds of ammo. I'm interested to see what the market looks like when this crisis passes.
