Mags not working with TNA WK180C upper receiver

[CA47]

Hi all,

sorry if this was already brought up, but I couldn't find any mention of it.

I have a problem with most mags not seating correctly after I changed out my WK180C's upper receiver for the TNA one with the handy dust cover. I have tried it with the Lynx 180B lower receiver as well as with the original installed. Both just won't let any mags other than the Cross Ind. Pistol Magazines. IS there a fix for this? Has anybody else had this problem?

Thanks

Just to be clear, I love both True North Arms and Spectre Ballistics. Not trying to slag anyone's products here, just trying to get this combo to work. The TNA upper with the Lynx lower makes a really sweet combo for the WK180C. So, if anybody knows what the issue is here, I would be so very grateful.

The uppers don't seem to like Pmags.

Haven’t had any issues running pmags. Lynx lower and tna upper.

What exactly is the issue? Loaded mag on a closed bolt can be an issue depending how/where your mags are
Pinned.

I had nothing but problems with the original platform and after trying these different parts. Ultimately, the solution was to get rid of it.

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.
