update, Sunday 24, February 5:18pm: Part II of the concept prototype build is up: FU25-12: 12 Gauge Auto Combat Shotgun Build: Part II
With the advent of the 80% home built weapons market becoming so popular, and the sublime freedom of making your own personal arsenal, has inspired me to create weapons of my own design.
The 12ga weapon pictured below is of my own design, a 25 round “Feed Tray” fed, gas impingement operated, semi auto shotgun.
It is constructed almost entirely out of chrome moly aerospace specification precision tubing and bar stock. The design incorporates a number of AR10 and AR15 components, such as buffer/spring system, trigger/safety group, a modified 80% forged AR15 lower receiver, these are proven reliable components, making the entire design much less complicated and is of a great savings in materiel costs and labor.
No promises, my intent from the beginning, and many factors could easily change this, to offer an 80% kit somewhere around $550 bucks plus shipping. I got to make a few bucks on each kit to make it worth the labor and materials. I’m not into it for money. It is something to accomplish, do my part lets say in regards whats coming down the pike. This is a true dirt people project, start to finish. Just a guy in his shop who loves him some Liberty and self determination. What better way than being a backwoods mountain gunsmith in West by God Virginia.
[FYI, I have a few kit weapons designs for future development, one of which is a .50 cal Ordnance Browning single shot rifle in an 80% kit form, I’m hoping it can be offered for under a grand. Thats a tough goal, but I have some different ideas on a .50 regarding how it is constructed which will keep materiel/labor costs to a minimum. We will see. The FU12-25 proceeds will go towards developing the .50cal single shot kit.]
The FU12-25 “Feed Tray” feature, is a captured double row single feed, 25 shot shell capacity, magazine, with a quick release lock on slam, closing provision, allowing for the operator to replenish his ammunition without the typical magazine swap of most magazine fed weapons. No magazines to handle, need for very large, heavy and bulky foot long large capacity mag pouches taking up valuable MOLLE real-estate. You get full time tactical reload capability without dropping a mag, while a shell is chambered, or bolt locked back. How to manage reloads can be accomplished in a surprising number of practical ways utilizing current off shelf gear. More on that in later news as the project proceeds.
The sketch below is a rough draft of the concept. Currently I am in the process of fabricating and machining an R&D model for testing & evaluation. The basic form will not depart much from the rough draft drawing below.
One of the ideas which have come out of the original thinking of the weapon, is to offer it in an 80 Percent “Kit” form. It may be comprised of a kit in a semi completed set of sub assemblies state, requiring basic steel welding, along with required machining which can be accomplished using common metal fab/machining resources used in the making of AR and AK platform 80% builds.
This is a brute of a weapon. There is nothing GUCCI, graceful, or phoo phoo about it. It is a down and dirty, so ugly its beautiful, pre CNC era, metal fabrication and machining produced weapon. Built to be rugged, reliable, lethal. You can see for yourself it has a certain Karl Gustav Sten sub machine gun style to it. The design is on purpose, as much as form follows function as it gets. Its not called the FU12-25 for nothing.
If the bolt/gas impingement Feed Tray engineering works out without encountering unusual R&D problems, I hope to have a fully working beat to shit reliable weapon ready to begin offering 80% kits by spring. The devil is in the little details. I have a basic metal fab shop. Been a welder/fabricator, basic machinist for 43 years. I’m a frugal sonofabitch, old world metal craftsman, less is more, common sense and absolute reliability, no bullshit kind of guy. If I am able to make this work within the realm of following those aforementioned criteria resources and my skill sets. it should be a weapon of robust reliable lethality.
I’ll post photos at various stages of the R&D unit.
If I can produce an 80% kit and your interested in obtaining a kit for yourself, leave a comment.
Thanks much for checking this out.
PS, ASAP I’ll make a complete FAQ like list of the features of the FU12-25 as time permits. There are some features which only can be settled on thru R&D.
