On July 13, 2014, the unofficial yet famous K'nex war will take place in Freemont Ohio and luckily this year I coming back a veteran. With all the experience and advice I got from last years war I will be a stronger competitor this year, with more powerful and sturdy knex guns. With all the fun and preparation involved in getting ready for a knex war it made me think of all the iblers who don't get to come down to Ohio for the war, so I decided to try one of my ibler's war guns at the knex war. I ended up building the Red Book of Westmarch's R5 Defiance, A bolt action K'nex gun specificly designed for K'nex wars, and while he admitted he hadn't tried it at an official war he had tested it rigorously so he knew it war reliable. My stock version worked really well, it hit the range that Red had showed and it was pretty reliable. As you can easily tell by my final product, I changed practically everything about the gun. Why? Why would I do that if I was happy with it? Well there's a small difference in being happy with something and being confident with something. While the R5 was very reliable, I had trigger issues and a little chambering issue. That also being said I also have an engineering saying that goes building something is easy mindless work, making something your own, that takes skills. So I made my R5 my own and changed everything but the magazine and general body. I added: a new trigger mechanism that increased pin draw ( the stock pin draw was fine too), magazine lock ( I have a vendetta against friction in K'nex guns.. ), Upper chambering mechanism (because it makes the chambering smoother in my opinion), and a barrel (which prevents yellow rods from tumbling end over end). My modifications only increased the reliability and the overall functionality of the gun. I would definitely recommend building the R5 Defiance because it's a great gun and it'll definitely help you in a knex war. Like any gun though, try it out and make it your own before using it in battle! Anyway thanks for reading and if you have any questions I'll be around.
