I know someone was looking for a 15-22 MOE Flat Dark Earth but can't remember who. Anyway GrabAGun has them in stock $455.00 they also have the black for $495.77. Just a heads up.
And for those of you in Texas, dlshootingsupplies has them for $449 with free shipping, no tax, and no CC fees. Save some on tax. Does GrabaGun charge any FFL fees? It might be a wash unless you have a low cost FFL. Mine does them for $10 (CHL Holders).
