Does not fit - TANDEMKROSS Assembled DoubleKross Ruger 10/22 20 Rounds Rifle Magazine

We were excited when the doublektoss magazine arrived. It is a bit expensive for what it is. However, I did not mind paying a bit more for a product that appeared to have more quality and engineering into it. Sadly we didn’t even make it to the range with this magazine. I decided to check it out attached to my brand new Ruger 10/22 and neither side of the magazine would fit into the receiver. The magazine has resistance, going into the receiver, and will not lock in place if you even get it in all the way. Yes, I did make sure the magazine was facing the right way. Even if the magazine can make it all the way into the receiver much force is needed to eject the magazine out.
