The idea for a precision chassis system came about when I had picked up a type 38 Arisaka from an estate sale of a local Colonel that had fought in the pacific theater and had about 4 or so Arisaka rifles that were bring-backs. Through out the years since then, I believe these rifles were not protected from moisture or some other situation caused them all to be missing stocks and other external features. I picked one barrel action up for around $120 and began to look for options on how to get this rifle in a usable format. Due to missing a lot of external features such as sights, wood stock/furniture, grip, and other hardware, I looked into finding an aftermarket option instead of restoring this rifle to its costly original configuration. Many after-market stocks didn't quite do it for me in terms of modern features and coolness factor. 

On top of this, through my early research I found that the 6.5Sr Arisaka cartridge was relatively similar to the now popular 6.5 Creedmoor, while this gun being well known for an incredibly strong action(although having questionable steel alloy), this gun could have the possibility of shooting higher pressure loads similar to the 6.5 Creedmoor in performance. It was from that day forward that I set out to design a precision system for this rifle to both get this rifle up and running on top of experiment with different design features, technology and have some artistic freedom.

Some of the basic features and ideas I had for this project in mind all revolve around most features precision rifles are sold with today. At the start of this project I was first getting into advancing my skills at being more artistic and less utilitarian in my 3D modeling. Some basic influences that lead to the creation of this rifle included video games such as Half Life 2, Borderlands 2 and some current precision rifles like the Barrett MRAD and Ruger Precision.  
The geometry of this rifle is built up of many chamfers and other organic & innorganic shapes meant to look almost like it was grown with crystals on another worldly planet.  As guns continue to further develop in technology, the look and design also has to progress in some way to keep up with current social trends and what people feel is the look of a “modern” firearm.

 When breaking a Type 38 down to its basic firing components, not much of it is that different from a modern firearm in terms of aesthetics. Some of the only non modern features on it include the safety being housed at the rear of the bolt and a lackluster clunky trigger. On top of all this being internally magazine fed. To reiterate the general goal of this project, the AR154K4 is primarily meant as a platform to help me express and show my design process and skills, along with still having a functioning product with many modern features most rifles include today. 

This project is supported by Timney Triggers, which was kind enough to give us their light weight, competition trigger packs which fit both the Type 38 and Type 99 Arisakas, and can reduce their total trigger weight to around 20% of original. 
The AR154K4 has no less than 800 hours of painstaking design work, with pounds of plastic filament burned through, creating test prototypes. A project of passion that was near 3 years of work. Many of the mechanisms involved with the folding stock and adjustable features were engineered from the ground up, being of completely original design.
