Has anyone experienced the Korean MP5 Mags not fully seating in their Bellator 89?
Yep. My BA89 came with a single Korean Mag that fits, but barely so. I have a couple of the newer Korean (ATI-marked) mags that wouldn't lock up at all.
They fit perfectly in my Bobcat, Cohaire, and SW, but they will not lock up in the Bellators? WTH? They are close too. I've wiggled back and forth tried everything. No go. Any suggestions?
I progressively fitted the newer (ATI-marked) mags (by lightly touching the front shoulders with a Dremel) so that they would lock up but fit very snugly.
Being real proud of myself, I proceeded to the range where I then had feed issues with all of them (to varying degrees). The one that came with the gun came out second best to one of the ATI mags.
The best mag (new ATI) would
generally work for about 12-15 rounds before becoming FUBAR'd. The worst, also a newer ATI, would only make it about 4-5 rounds. All were completely inconsistent in performance.
In defense of Bellator, their manual lists acceptable mags and none of them are Korean/ATI. Blaine also warns potential buyers of this issue and suggests using only HK mags.
To me, it looks like the ears on the HK mags are different and the Korean follower feels like it isn't as free as the HK. That could be a spring issue or the fact that the Korean mag is parked, inside and out.
