    I made it, and it's AWESOME. I just have one problem: I need a solution for the pellets spilling out when i hold it downwards. I also am wondering if there is an easier and faster way to load the bullets, and if a larger pvc will make it have a higher fps.

    I have a suggestion. First, for the pellet to not fall out of the barrel find where the bullet should rest and cut out a section on the barrel. Many airsoft guns have what in called the "hop up unit," this unit holds the pellet until fired out of the barrel so you can take the hop up from an old gun replace that section of the barrel.

    Second problem. I would not expand the air chamber because doing this would take longer for you to fill the air chamber still having a FPS very close to the original.

    I hope this helped you. :)

    Very cool! Glad you like it. You can keep pellets from falling out of the barrel with a bit of paper/tissue as wadding, just like an old muzzle loading musket is loaded. I don't have a faster way to load pellets.

    I have a problem with this, I sealed the bb with hot glue just as it said, and put it all together, and there Is a leak coming out of the end of the barrel, I am confused and kinda aggravated.

    probably is the O ring. Put some pipe thread paste on it and it should seal better.

    from the shrader valve, stop askking.

    i reckon for what its worth make a 'magazine' that you can manually (a rod that goes into the mag) push up a bb through a x cut piece of paper into the barrel

    how does the air from the bicycle pump go into the chamber? Please respond, I'm thinking of building one. Thanks :)

    what is a schrader valve? And also how far does this shoot or what fps does it get, thanks again.

    how does the air from the bicycle pump get into the chamber??

    This is just awesome. What's your favorite replica weapon?

    I made it but do you side the pellets down the barrel or what
