Anywho, yeah not sure how good anyone is anymore (as if I ever did) but be careful taking it apart, if you do so that is. It was a bitch to keep everything together and not loose anything. But this helped- http://nerfhaven.com...topic=12589&hl=
I just went to Osh and got all I need for this gun (exept the tire valve and pump) and they acually had like 8 different sizes for the couple. Part of why this gun got huge ranges is because the back of the exteneding part is 1/2" but it get's smaller slightely. This makes a bette seal and more preasure to build up behinde the dart.
It's weird I hadn't seen this coupler before at my Osh. They had sizes like 1/2", 3/4", 1", 1 1/2", and so on till' 3".
Does anyone know what he used for the breech at all??? Because I have researched this name he gave us on google and nothing came up that was remotly like it...
