I like to clean my guns with hot water. That's not a problem with a hooked breech rifle, just drift out the wedge and stick the breech end of the barrel into the bucket of hot water and clean. But if you have a pinned barrel gun there's no way to put the breech into the water so you need to run a hose from the nipple or vent hole into the water. Most places sell a deal with a 1/4x28 tube and a length of plastic hose that you can screw into your vent or where the nipple goes to get the job done but then normally want about $5 bucks for the deal. I found an inexpensive alternative, just pick up a 1/4x28 Zerk fitting(some people call em' grease fittings) and drill out the check ball and spring the attach a piece of 1/4" plastic hose to it and there ya' go, a vent/nipple adapter hose that'll let you clean your pinned barrel gun in a bucket of hot water.
