There's still a lot of details to be added to the travel limiter. I need to sculpt a lock and some nuts'n'bolts on the top and the bottom need some serious beefing with plast-card to bring it in-line with the look of the top. In addition, I need to make some hinges to hide the connection to the chassis itself.

But right now I'm letting it sit until the glue has dried completely, hopefully locking the barrel in place for good...
