Maybe I was a little bit harsh, I apologize for that but I think the design on this device is rather ingenious and a refreshing change to the "metal tube unscrew some parts" mech mod world, but I like to tinker with things as do alot of mech mod users out there. So, calling it junk because it doesn't fit your idea of easy is unfair to this device which alot of people might enjoy, the copper firing pin is easily cleaned through the battery hole with a long cotton swab and some rubbing alcohol. Ok, so it sounds like you have it together without the spring. Take the bottom off and take off the wooden side without the firing device. Look up on the inside of the remaining wood side where the lock screw goes, the spring goes in between the copper and wood right at the hole for the locking screw, and the locking screw actually goes through the spring when its in place to hold it. There is a little shelf cut into the wood so the spring will sit flat when in place, you may need a screwdriver or needlenose pliers to get the spring in that small space. If you keep the device I would recommend only taking off the bottom cap and the wood side that does not have the firing button so then you dont have to worry about the spring, that will give you easy access to the copper pin if you dont want to go in through the battery hole (you can also clean the trigger "arm" easily from there. Let me know if that gets you going again, if not i'll post pictures when I get home from work tonight
Thank you and apology accepted. I edited my perhaps too-harsh description. I was honestly hoping to love this device, but unfortunately upon receipt it just doesn't live up to my expectations. Here are some pictures along with my concerns
====================================
Here's the delrin positive pin assembly, which is secured only by the pressure of the two wooden pieces when they are screwed together. Without some sort of threading, I just can't see this design holding up:
====================================
Without disassembling the device, the only access to cleaning the pin is dealing with getting a long cotton swab down here:
====================================
Getting that tiny spring back in between the lever and top cap is...well...difficult.
====================================
Cheap plastic battery screw:
====================================
And lastly, one of the top brass screw inserts has already pulled out of the device. Unacceptable on a device of this price:
