All 3 versions now there, goes in descending order (v3, v2, v1) v3 slideshow https://www.instructables.com/id/UKP-v3/ Back Story (skip if you don't care who I am) Hello! Most people probably have never heard of me, and for those of you that have, you're probably in the same boat. I was part of the raise of knex guns, you could say. I helped to change the idea of knex rubber band guns back in my day, 4-5 years ago I think. And then began to dabble into knex firing guns. Project History The UKP was my take on the common pistol of knex. Way back when there were two options for a sidearm, the TDS or the GD-1. Both in their own ways, were excellent systems, except the GD-1 was massive, with a larger round and slide action, While the TDS featured a more compact design, without a slide (until later, still not the best). The original UKP was designed to create a medium between the two, and that it did, with some minor flaws. It's biggest set back was the lack of a slide. The UKP v2 ,2.1, 2.2, 2.3 and so on were my attempts to fix that problem, which it did well at, but it wasn't a complete success. It was never released due to my inability to work out the kinks. (note that the UKP v2 is pictured below) The Current UKP V3 I've come to realize, that I will be going to college soon, and that all knexers release something spectacular right before they leave the world of knexing for a while, or longer. So the UKP v3 will be my attempt on that. I will open a slideshow and various youtube videos throughout the production to keep anyone interested informed. This project has a deadline of mid august, as I leave the 20th. Summing Up If you've never built one of my UKP's before, I highly suggest you do, or at least keep an eye out for the latest release. They feature high removable magazine capacity, exceptional range for the pistol class, and an overall realistic feel and performance.
