  • The DIY STEN Gun
    The DIY STEN Gun Practical Scrap Metal Small Arms Vol.3 By Professor Parabellum Plans on pages 11 to 18 Introduction The DIY STEN Gun is a simplified 1:1 copy of the British STEN MKIII submachine gun. The main differences however include the number of components having been greatly reduced and it's overall construction made even cruder. Using the simple techniques described, the need for a milling machine or lathe is eliminated making it ideal for production in the home environment with very limited tools. For obvious legal reasons, the demonstration example pictured was built as a non-firing display replica. It's dummy barrel consists of a hardened steel spike welded and pinned in place at the chamber end and a separate solid front portion protruding from the barrel shroud for display. It's bolt is also inert with no firing pin. This document is for academic study purposes only. (Disassembled: Back plug, recoil spring, bolt, magazine, sear and trigger displayed) (Non-functioning dummy barrel present on display model) Tools & construction techniques A few very basic and inexpensive power tools can be used to simulate machining actions usually reserved for a milling machine. Using a cheap angle grinder the average hobbyist has the ability to perform speedy removal of steel using a variety of cutting and grinding discs. Rather than tediously using a hacksaw to cut steel sheet, an angle grinder fitted with a 1mm slitting disc will accurately cut a straight line through steel of any thickness in mere seconds. Fitted with a 2mm disc it can be used to easily 'sculpt' thick steel into any shape in a fraction of the time it takes to manually use a hand file.

  • Firing Process of an AR-15 Firearm Platform
    Firing Process of an AR-15 Firearm Platform Introduction of the AR-15 One of the most universal firearm systems ever created is the AR-15 platform. The AR-15 platform is a semi-automatic firearm based on the design of Eugene Stoner’s original AR-10 produced by ArmaLite in the late 1950s. In 1959, the AR-10 was converted from using a 7.62x51mm cartridge to the much smaller 5.56x45mm cartridge and the AR-15 was born. The AR is actually a shortened designation for ArmaLite, the firearm manufacturer which originally designed the firearm. The M-16 used by the United States military is based almost entirely on the AR-15 design. The construction of the AR-15 is mostly aluminum and many different manufactures have a version of their own with many of their parts being compatible with others. The firing process is how a firearm is shot, sending a projectile down range to the designated target.A Colt brand AR-15 is displayed in Figure 1. Figure 1: Colt AR-15 Hammer Pulling the Trigger Sear Trigger Assembly: 1. Trigger 2. Sear 3. Hammer Sear/Hammer Catches 4. Sear/Hammer Catches Trigger Figure 2: Trigger Assembly Every firearm has a safety with at least a fire position and a safety position where the gun cannot be fired. Once the safety is changed to the fire position it is ready to be shot. To fire the gun the trigger must be pulled. When cocked, the front sear catches the hammer and holds it in place. One the trigger is pulled the sear slides out of the way of the catch on hammer, releasing the hammer.

A total of 1,632 GLOCK firearms were used to generate a sample of the same size. Our research hypothesis was that by comparing only firing pin aperture shear marks no cartridge cases fired from different 9 mm semi-automatic GLOCK pistols would be mistaken as coming from the same gun. Using optical comparison microscopy, two separate experiments were carried out to test this hypothesis. A sub-sample of 617 test fired cases were subjected to algorithmic comparison by the Integrated Ballistics Identification System (IBIS). The second experiment subjected the full set of 1,632 cases to manual comparisons using traditional pattern matching. None of the cartridge cases were "matched" by either of these two experiments. Using these empirical findings, an established Bayesian probability model was used to estimate the chance that a 9-mm cartridge case could be mistaken as coming from the same firearm when in fact it did not (i.e.

  • Accuracy International
    AXSRACCURACY INTERNATIONAL USER`S HANDBOOK Part No AI-15653 Issue 1 INTRODUCTION i Accuracy International was formed in 1978 to design and build tactical rifles. The original design ethos combined two factors into a unique package, namely the incorporation of performance enhancing features learned in Olympic and international target shooting onto a platform exhibiting full military ruggedness. The current designs faithfully follow this original concept, but also benefit from over twenty years of continuous improvement. These improvements are not cosmetic, instead they are driven solely by the needs of the users, highly trained military and police units in over 60 countries worldwide. Such units are exposed to ‘live’ tactical situations on a daily basis and in the most demanding environments where first shot accuracy is critical. All components are manufactured to Accuracy International`s designs to ensure that they are optimized for the function they must perform, something that cannot be achieved with a re-purposed sporting weapon. The AXSR multi-caliber rifle is an evolution, which builds on Accuracy Internationals established family of highly successful AW and AX rifles. Being a bolt action rifle with free floating match grade barrel and a magazine capacity of ten rounds, it fulfills the need for a highly accurate long range sniper rifle. Like the AX series, the AXSR rifle utilizes an aluminum chassis system, which ensures insensitivity to temperature and humidity, thus ensuring a constant zero. The fore-end tube design provides multiple mounting points using KeyslotTM technology for accessory rails, sling attachments and bipod mounts. The AXSR rifle also incorporates integral RRS compatible dovetail rails for use with a wide range of bipod, tripod and accessory mounts.

  • Introduction to US Bomb Fuzes
    This is a brief introduction to US bomb fuzes. It is an incomplete but ongoing work. As I prepare more pages I will add them to this section. The US Army designates its bomb fuzes with the letter M followed by a number then any modification to the fuze is indicated by the addition of the letter A followed by a number. Thus: M113A2 indicates the second model of fuze number 113 Fuzes under development are designated by the letter T followed by a number then any modification to the fuze is indicated by the addition of the letter E followed by a number. Thus: T114E3 indicates the third modification to the development fuze number 114. The USN designates its fuzes with the abbreviation for Mark, Mk followed by a number then any modification to the fuze is indicated by the addition of the abbreviation Mod followed by a number. Thus Mk 415Mod3 indicates the third modification to the fuze mark number 415. Any fuze accepted as one that can be used by both services is designated by the prefix AN. Thus: AN-M220A2 indicates a standard army fuze Model number 220 with two modifications that can be used in naval bombs AN-Mk 218Mod3 indicates a standard naval fuze 218 with three modifications that can be used in An example of a nose fuze. army bombs. Fuzes in American usage are marked with the following information: Fuze designation Manufacturing details: • Lot number • Manufacturing codes letters • Inspectors Initials • Inspection date Firing delay Arming delay Time scale (if any) Coloured paint to indicate some special characteristic of the fuze (if any) American fuze hole gauges are as follows: For large bombs 50.8mm (2inch) For smaller bombs 38.1mm (1.5inch), Smaller bombs include fragmentation, clusters, photoflash or practice.
