I bought these today at the gun show, got home and pulled one on the right out of the package and it doesn't fit in my rifle. The base plate is wrong for my gun. The only difference in these mags is that one has a "shiny" base plate and one has a "matte" base plate. I paid $35 each at the show; I'd like $30 each plus $5 priority shipping. USPS money order only and if you buy both I'll throw in free shipping!! I'd also trade straight across for BDM mags. ETA: Up for sale is a rail mount for the front sight base. I used it for about 6 months on my patrol rifle and then decided to get a surefire forend instead. It is in excellent shape except for a little rubbed area were the larue mount attached. These retail for $35, I'd like $25 shipped USPS money order only...this will go out priority mail (worth the 5 bucks shipping I am charging anyways.
