A&K Ammo Box Wired Winding Pressure Switch for Drum Mags

"This is a vital tool for those using Box mags, Auto wind will destroy your box mag and sound wind fails after a while.

"While this is a vital tool to use A&K box mags with sound control, it’s also a piece of crap. Maybe it was the box mag but after only an hour of use, the box mag was not responding to the switch. I’m not sure what one broke but… neither should have broke so soon is my point.

Pros:
-Vital component for A&K Box Mags
-Cheap

Cons:
-Cheap design (breaks easy)

Rating it 3 stars solely for its importance. However, I recommend using the Cybergun 2000rnd box mag, that one is sound control non-switch. Much better in comparison.
