GBBRs are great! But ... To be blunt,

You over paid for a garbage gbbr. WA / G&P are dated, you should of researched and looked into GHK if you had the cash to spend on a G&P or second place, WE.

I would sell it and start with a better base, or you can try modding ghk mags to work...with it...

If you want to try your lucky with G&P.. probably need to find an expensive gundoc to look at it to address your issues.
