KRG Bravo Stock Questions

[jladd]

I have a Seekins Havak Bravo rifle that I have 2 questions about the stock.

* will the MTD exterior M-Lok weights fit my Bravo forearm with 2 slots?

* I took the forearm off and 2 small flat threaded nuts fell out and I didn't notice where they went?

Thanks much!
