Crossfire Dye Valves

Have a couple of valves to move that I picked up in deals. Crossfire 4500 and what I think is a Dye(has a Dye gauge) 4500. Both have marks from when they were removed and I have not tested either. I guess $30 each or trade for gear ,Mag parts, hoppers, etc. Make an offer I'll probably take it.

if you can put a fill nipple on the crossfire, I will trade a Halo B for it. LMK
