We have received, my son and I a silicone oil to lubricate the pistol ball that I bought at the same time. I confirm that this oil is very effective if I refer to a nice bottle of collection, ageless, engraved "grenadine" and that has not made a fold out effectively face the cannon projectile. I keep a relic, to prove that Ultrair it's cheap, but it rocks.
By cons, it would take you stipuliez on your user manual, as Ultrair, is used only in a gun barrel, as my dear love I love (my son is normal ...) made a test pchitt in the kitchen, but I've discovered that when I finished my trajectory in the refrigerator door (right leg slides in the left, the embossed head in the door and right hand that would prevent me from crumbling me, sliding in the same direction).
This small jewel of technology, which does not take more space than a quarter of mobile is developed by the company "ActionSportGames" .... j''aurais had to be started by reading this c ... It is true that it was sport ...
Yours Mr. Amazon
