Listing is for one magazine only, but I have seven left as of 10 March 2012. Two are shown in the photos.
This magazine was manufactured long ago by Federal Ordnance to serve two rifles of the same caliber - the AR-180 and the AR-15. Having tried the magazines in numerous rifles of both types, I have concluded to sell them as AR-180 mags, since the fit and lockup were near perfect for that rifle, and not so perfect for the AR-15. I only had one Sterling-manufactured AR-180 out of nine I tried that wouldn't fit, and that was in the early 18XXX range. The rest, and the several Howa and Costa Mesa guns I tried, accepted the magazines easily and achieved a tight lockup with no wobble or drag. These magazines were manufactured this way and are not the AR-15 mags being recut today to fit the AR-180. They are in as new condition, but being sold as used, and may provide a great alternative to the spendy factory original high capacity mags so seldom seen on the market today. There is a three-day inspection period to see if the magazine will work for the buyer, but the buyer must return it in EXACTLY the same condition he received it and assume the cost of shipping in both directions. Personal checks are accepted, but shipping will be delayed seven days to allow clearance by the bank.
Buyer to pay actual cost of shipping. Insurance, if requested, is at additional cost to the buyer.
