Mags not working with TNA WK180C upper receiver

lol - ok, ok...

Sounds similar to a magazine retention issue in the Jard J180, messaged the Crover to see if he ever fixed his.

The mags (original M16 ones as well as pmags) just won't stay locked into the mag well. They just pop out with a mild shake of the gun. If I load in a mag with the BCG held back, the mag will pop out when I release the BCG forward. The same thing happens if I load in the first round manually and resecure the mag. The mag will pop out on the return of the BCG forward.

Could TNA and/or Spectre weigh in on this? They are both great companies and must have seen this before and know a fix for it.

Sounds like a crappy magazine catch/release, or it isn't screwed in tight enough.

indeed,

sounds like the mag catch isn't grabbing the mag properly
they can be removed from the gun and filed a tiny bit narrower till they fit
we're talking like 0.005" to start

sometimes there are minor tolerance stacking issues when combining numerious parts
imagine the mag is in spec but on the tighter side
the bolt catch is the same as well as the slot position in the lower
each part individually is good but as an assembly they don't work
