Is it a TM G18? If so, I might still be willing to consider a trade + cash offer as I have a friend looking for one. I should also mention, the MX5-Pro I am selling as the ICS style receiver, not the Navy style. Basically, this is an ICS-18 with the nylon fibre RIS swapped for the flash light foregrip.
Edit: All original packaging included, which includes two highcaps.
