I recently bought a new 16" YHM Spector Length Upper with YHM Diamond Forearm to install on my custom DPMS lower. And I'm wanting to install a piston system on this 5.56 upper. Does anyone know which specific piston system will fit this YHM upper and YHM forearm?
Thanks in advance!

Good question. I think you'll either have to email whoever you are buying the piston kit from to ask them directly, or email YHM and ask them which kits will fit their uppers.
