Some of the noticeable exterior differences of the magazines we are distributing are the markings which state the magazine is made specifically for the Canadian market and specifically for the Ruger 10/22 rifle. Some other physical exterior differences are that the alloy feed head is not removable as well as the alloy feed head is also a slightly different shape. Please note that these are the physical exterior differences that I can see in the office. I am certainly not an engineer!! Our company has been working with GSG for quite some time as most of you know developing this magazine specifically for the Canadian market and and we are very happy to finally be able to offer this product for sale. This specific magazine has been designed, manufactured, tested, marked and advertised specifically for the Ruger 10/22 rifle and the Canadian market.
Cheers,
Ryan
