I have 2 and sold another. Use it dry. Clean the piston and mag tube with hoppes let it dry and use dry lube on the rails. I have found that dry works best in all weather conditions especially cold weather. I asked an exhibition shooter who uses SX4s and shoots thousands of rounds through them and this is his recommendation.

 

I wonder if you are referring to Steve from the Focus Target Life? I watched his sx4 cleaning video. on the video he puts Otis dry lube on all moving parts, sprays inside of the receiver and wipes the mag tube but keeps gas system dry.

 

Yes absolutely it was Steve Gould.

 

spray it down with Rem-Oil .....wipe it dry and go shooting

 

I have kept a light coating of Rem-Oil on the gas system of my two SX2s and my SX3 for years. They all run like tops, including the SX2 Sporting which has fired many thousands of rounds and never jams. Plus, I think the fouling is easier to remove than if they were run dry.

 

Thank you everyone for your comments. I will most likely just use very light coat of breakthrough clp on moving parts mag tube and gas system and a drop of synthetic oil on rails.

 

Been shooting that style of gun for 25 years. Shoot it Dripping wet with break free clp.

 

Outside of mag tube and inside of piston wipe with a cloth that has a small amount of your favorite lubricant, so there is barely any on those two parts. Outside of piston and inside of cylinder keep completely dry after cleaned. I have gas guns that run for 2500 rnds with no issues doing that, cycling or wear, but it's best to clean every 600-800 IMO. I use Hoppes Benchrest with weatherguard.

 

You can run it wet, shooting sporting clays or trap, I would not run it wet in the field. Field loads tend to run dirty and if you are in cattails and such all that oil just attracts everything.

I wipe mine down with rem oil or clp, just a light film, never have issues. I have an SX2, 3 and 4.

 

Hi everyone I received an answer from Winchester costumer service the did confirm to use lubrication on the gas system. As suggested by some I will use minimal coat of break-free CLP on the inside of the piston and on the mag tube where the gas piston movement happens. Don’t see the reason to put it on the outside of the piston.

“Thanks for reaching out. Yes, that is correct, you will want to apply a thin film of oil to all parts of the gas system after a good deep clean”.
