Arfcom users report seeing Bushmaster carbines and Remington R-15 rifles on sale at Wal-Mart. On one hand it seems significant that the world’s largest retailer is selling The Black Rifle, but on the other hand they are the last retailer I look at for firearm industry trends.
Wal-Mart ceased firearms sales in 2006 but earlier this year reintroduced them to about 2000 of their stores.
