Cost to retrofit the Spin-Loc

Just got off the phone with Airforce and they said the cost to retrofit the Spin-Loc onto your gun is $50.00 plus S/H and labor. hope this helps you.
Spin-Loc would be a great idea if you have a TTTA because it would be so easy to connect with out having to dick around. just screw it on tighten down the set screw and your done. They have no price on retrofitting the old tanks to the new ones with the quick connect and gauge yet she took down my number and said she will call me when she finds out. i will keep you posted
