A reader direcxts my attention to this deal: "New C Products 30rd .223/5.56 curved Aluminum Lightweight magazine for AR15/M16 type Rifles. Feature Chrome Silicon Springs, Black Teflon coated Finish, and C-Products Orange or Black anti-tilt follower." Buy 10 or more at $8.50 each from AIM Surplus.
He notes: "I ordered a dozen for myself and the shipping was less than $11. Not a bad deal." I have dealt with AIM in the past and found them to be excellent on quality and service.
