Stranded wire to terminal blocks

Skup sent me a YouTube link about wire ferrules. I didn’t know these existed until I watched it but I knew instantly it would solve the poor wire retention problem at my Pmags. I bought a similar kit on Amazon Prime for under $30 and had it in a few days. Worth every penny if I never use it again.
