Careful not to tear the bucking getting the unit on and off. Add white lithium grease if you're having trouble (less is more).

Do not use white lithium grease on buckings, it is the wrong type of lube for buckings!


Picture below shows the types of lube I keep around for installing Hop-up buckings. From right to left,
Silicone spray - This stuff is sold at all hardware stores and works great for cleaning barrels, but because it’s spray does not adhear very good making it so great for hop-up buckings.

100% Silicone Oil – This is somewhat hard to get, and most hardware stores don’t carry it. It’s a little thicker than the Silicone spray although not by much. I use it for lubing valve O-rings on gas guns and coating Teflon tape (AKA plumbers tape) because it does not have any additives and is 100% pure Silicone Oil.

Silicone vacuum grease –This stuff is great due to its high viscosity and good sealing and lubricating ability. I use this on all hop-up buckings and air nozzles. It’s available on ebay for around $30 with free shipping for a 5.3 oz tube. Also available in smaller amounts for around $10-$15.




Just apply a little bit. As you can see it’s very viscous.



And smear it around to coat. You should have a very thin layer.

Sir, much more detailed than I could have hoped to be. I was told to use White Lithium...

White lithium's more useful for gears and such, while a silicon oil is best for the cylinder assembly and hop up

I just got some, so I'm a little White Lithium-happy.

Thank you.

If I were you, I would just take it in to my local AirsoftOutletNW store and have them put it in for me, they're pretty friendly people and they would usually do it for free, but then again, you might not live that close to them...
