We are constantly making updates to our parts. Because of this, we recently gave a much needed update to our Mini-14 clip spoons and Mini-30 magazine loaders. These parts now function with older magazines as well as the new magazines. Typically older magazines include a square welded tab at the back of the magazine.

Gen II parts will be manufactured with our own internal production capacity from ABS plastic. All our engineering and testing show that this is the right move forward for a stronger, cheaper, and shorter lead time part. Take a look at the images below.
Any plans for a AK stripper clip to AR-15 mag?
No, The combination of really stiff springs in those magazines and the way the 7.62 rounds stack in a strait magazine body make it virtually impossible to push more that 3 rounds in at a time with a stripper clip.
