Has anyone experianced the Korean MP5 Mags not fully seating in their Bellator 89? My boss and friend each bought a BA89. Both are very happy with them. I purchased a 20 lot of Korean mags and we all split them. They fit perfectly in my Bobcat, Cohaire, and SW. But they will not lock up in the Bellators? WTH? They are close too. Ive wiggled back and forth tried everything. No go. Any suggestions?
