And people are starting to accumulate enough of the "standard" AR's - 5.56, 9mm, 22's, and it's showing in the market. Prices are falling, and sales are leveling off. Mfr's will begin offering more AR stuff in non-traditional calibers, and the market, saturated with "normal" AR's, will have increased demand again.
6.8, .300, and 45 are gonna be more popular in the future.
