When you are working with the best internal upgrade parts in the airsoft world you're going to need to compliment that with the best lubricant in the airsoft world, therefore Madbull have introduced their Ultimate Silicone Oil! This ultimate silicon is made in Germany and it's characteristics have been crafted to cater to the airsoft perfectionist.
As always with Madbull this is another great product. Bottle cap has built in applicator great for that automatic drip (lol) that makes filling a propane adapter without spilling excess oil everywhere. This also happens to be the proper viscosity oil KWA recommends for their LM4 GBBR.
Recommended viscosity for the KWA LM4,
Comes with a fine tipped spout,
Great for propane adapters.
I am required to type 30 characters here but I really have nothing bad to say about this product.
