Good idea, but next time when taking the photos, don't use your flash. The photos should turn out a lot better.

who is macro?
Ballistaman in reply to shot789Jun 20, 2010. 1:07 PM
Macro is a mode on your camera that allows you to take photos closer with more detail. you normally push left on the d-pad. The macro symbol is a little flower.

What's the extra piece of pvc for? Is the orange bit a glue stick cap? Also what is the threading for?

Thanks,
Thing 2
kve23 in reply to thing 2Feb 26, 2011. 8:18 AM
so you can stake it to the ground and yes that is a glue stick cap but no there is no threads. i think your thinking of the spring.
thing 2 in reply to kve23Feb 27, 2011. 8:23 AM
How do you get the glue cap to work for you without bending or poking a hole in it?
kve23 in reply to thing 2Feb 27, 2011. 1:23 PM
i put the pin all the way through and it really doesn't dent it
Fire Explorer 3 says: Dec 2, 2010. 7:43 PM
Hmm...tryina' figgure out how to mount this with the 45* angle, so i can use it under my gun w/o the bb's hitting my gun, or the ground, or shooting sideways...or, a way to use it as a real shotgun, but with better range... (Bigger pipe and spring, but how to quick reload...any ideas?
shot789 (author) in reply to Fire Explorer 3Dec 16, 2010. 5:10 AM
For a quick reload you can cut a small line in the pvc pipe and use a screwdriver or something to push it down. I have been meaning to post how to make a undermounted grenade launcher/ shotgun but i just havent had the time but i will soon.
kve23 in reply to shot789Feb 5, 2011. 8:03 AM
MASTERKEY!!!!!!!!
Fire Explorer 3 in reply to shot789Dec 18, 2010. 1:39 AM
Please do...cuz it may well become my primary... my crappy crossman crapped out on me...
kve23 says: Feb 2, 2011. 6:58 PM
ive gotta make 1 like that
wawhosed says: Nov 26, 2010. 10:15 PM
This is a good project, I have made one before. Also, you put a s****y spring in there.
evilgenius32 says: Aug 16, 2010. 4:12 PM
I like how the 45 degree angle keeps the spring from coming out. I tried one like this but without the elbow and had troubles with it. This one would work a lot better.
siv says: May 19, 2009. 8:27 AM
would the mine work for paint ball also or not
shot789 (author) in reply to sivJun 2, 2009. 9:53 AM
ya but you cant put the 45 degree angle on unless you use bigger pipe
Thundertydus in reply to shot789Jun 11, 2009. 9:53 PM
Mount it on your gun and add on a better handle and abolt action design, it makes a great nade launcher
Ballistaman in reply to ThundertydusJun 20, 2010. 1:08 PM
put some thin paper on the front of a pipe without the 45 degree angle when doing this. it keeps the bbs from sliding out.

No problem, it's what i do.
HeadBanger in reply to ThundertydusFeb 6, 2010. 7:11 PM
Yeah, that's a great idea. Thanks for that.

 Hmmm... Airsoft under barrel shotgun?
gregsmith55 says: Nov 23, 2009. 1:55 PM
so u put the spring and glue cap in put the screw in and push spring down and put nail in to keep in place????  also do you jus put the bbs/flour in ontop of the spring and stuf im a lil confused
shot789 (author) in reply to gregsmith55Nov 24, 2009. 4:08 AM
what u do is  put the glue cap on the spring and use a stick or something to push it down then put the nail in the whole so the spring is pushed down. then you put the bbs or whatever in it and then when the nail comes out the spring will shoot up and the bbs will come flying out.
gregsmith55 in reply to shot789Nov 27, 2009. 10:59 AM
alrite thx
2bad4u says: Oct 23, 2009. 6:41 AM
my friend and I are huge into airsoft and have thought about making this design but we can never find a spring the size we need and the power we need it to be... any suggestions...
