That's pretty neat actually. It's nice to see people still coming up with quality ideas to alter the SKS after all these years.
I really like that they incorporated the AR mag into the design. Pretty much covered all the bases of modernizing the SKS.
Our G9 also incorporates the AR mag at a far lower cost. Ours also, "pretty much covers all the bases of modernizing the SKS".

Marcus... I know that you are sensitive about your mag adapter, but this thread has nothing to do with your adapter. This is a stock that incorporates a removable magazine, and uses an AR-15 mag release. This is nothing new. There are many other brands out there that make stocks that add removable magazines to guns that didn't have them. Your adapter is unique in how it attaches to the gun and that is your design, but you did not invent the removable magazine. It's just rectangular hole with a spring loaded release. The hole obviously has to be the size of the mag being used, and the release being used is a design that's been used on millions of other guns for decades. Nothing has been stolen from you.
As far as your adapter covering all the bases of modernizing an SKS, I'm pretty sure your adapter doesn't allow the user to use an AR style stock, AR style grip, picatinny rail, or keymod hand guard.
