Does the flap feel like it would warp enough to be unusable?

[Zorns Lemma]

You should up all your sizes in the flap valve to 3/4" nominal and thus put less stress on the hinge. The easiest way to do it would just be by replacing the 1/2" coupler with a 1/2" to 3/4" reducing slip->slip coupler (or even reducing male->slip or expanding slip->female, if those are more easily found since threads on the end bit won't matter). The other way would be to get a 1/2" to 3/4" reducing bushing and 3/4" coupler.

Not at all. It is very flexible.

I really don't think that's all necessary. From the looks of it thus far, I highly doubt that the flap will break. In addition, I wanted to create something that was not very big or bulky and was just as small as the usual end cap on the back is. However, if this design does not live up to my expectations, I will be sure to take what you have said into consideration.

Yeah, my bad, I thought it opened up outwards. In that case, this is more awesome than I previously thought it was.

ohNO !
I make this thing last year, but failed!
Because the valve is not thick enough, darts fly out.

Gasket is good idea

[fallinouttadabox]

Does the gasket around the screw show any signs of wear? After a while, I feel like it might break at this point, and a small washer would be a easy fix, unless there isnt room for a washer without impeding the dart's movement.

Everything is in fine working condition and there is no sign of any leakage or wear throughout the whole thing.

Very nice. Very, very nice.

I know this may start to sound redundant, but have you placed your hand over the barrel to see if the plunger head still traveled?

I don't mean to sound like a jerk, but the seal of the device has been questioned 5 times in this thread and I have responded each and every time by assuring the inquirer that it does not in fact leak out air when the blaster is fired. It's very frustrating when I have said it so many times and people just keep asking the same questions over and over. I apologize for ranting on and on, but I hope you see where I'm coming from.

I have actually plugged the barrel with my finger and put the whole top of the blaster underwater and shot it. My L+L doesn't have a perfect seal so most if not all of the air that does escape does so by getting around the plunger head.

It seems like having to push each dart through the door with your pinky would be slower than opening a ball valve and simply dropping darts in to fill the clip. Don't get me wrong though it's a fantastic idea and appears to be working working quite well.

I really like this. I saw the swing check valves in action at the GridCode war and was impressed. This seems like a viable solution that is cheaper and less bulky. Well done.

Instead of using a rubber 'C', do you think it would be possible to just make a ring of hot glue? Seems like that would be a bit easier, but maybe I'm not thinking of something. I think I'll try this out this afternoon.
