This section ataces the stock to the main body. It also houses the firing pin. Be carefal because I show both sides of the housing. Ask for help if you need it.

PLEASE LOOK AT BOTH PICTURES

Be sure to read the image notes.

Picture 2-3: yes that is a broken yellow rod. I diddnt break this on purpose it was already broken from a previuos gun. If you dont want to break your connector you can use a orange connector.

Step 6: Trigger

I can't imagine this being strong at all. :(

It looks weak. Try to use a black rod as a ram and make a longer barrel. 2 connectors between trigger and bullet lock does not make for a powerful gun. There have been single shots that shoot around 70 feet and require no modded parts.
Tom Buckey (author)  DJ Radio4 years ago
Well the modded part does not make any difference to the range. Thanks for the advice I'll be sure to do that in my next gun.
Where did I say anything about modded parts? The short traveling distance of the firing pin makes the gun weaker.
Tom Buckey (author)  DJ Radio4 years ago
"There have been single shots that shoot around 70 feet and require no modded parts." There is where you said about the modded parts. Ill be sure to make the ramrod a black rod too.
Yeah, but that wasn't related to my first statement, the reason your gun is weak isn't because of modded parts, it's because of the short traveling distance of your ram. Oh and make the barrel longer, more connectors between the trigger and bullet lock mean more acceleration speed.
Tom Buckey (author)  DJ Radio4 years ago
Okay, thanks for the advice! I'm worling on a pistol for now!
If you know the stock is to big then why didn't you fix it??
It could be used as a cheekrest.
Could, but for one it would not feel good.
Tom Buckey (author)  Killer~SafeCracker4 years ago
Because I did make it smaller but took away the overall look of the gun. In other works it didn't look as good.
Seconded.
