I have three brand new Nine ball fill valves. I bought them not realizing I needed a larger size valve. I tried installing one but it didnt fit so still in like new condition. Other two are brand new. These retail for about $15 and fit TM and maybe KSC mags but other than that Im not sure. I would like to sell them all as a set. Just trying to get some of my money back to buy the correct ones. Price OBO. Buyer pays shipping and fees
