MPT-76- is a modular rifle designed by MKEK & Kalekalıp and produced by MKEK to meet the demands of theTurkish Armed Forces and to replace its aging Heckler & Koch G3 battle rifles due to most of them being near the end of their service life. The MPT-76 was designed for robust high altitude, all weather, extremely hot and extremely cold arctic mountain warfare as well as combat on easier terrain. It is certified to operate under dusty, muddy, wet, and areas of high and low atmospheric pressure such as high mountain or deep sea environments. The MKEK MPT is a rifle intended to take abuse and extreme mistreatment and still maintain high accuracy and reliability in order to survive in true battle environments.
FN F2000 is a 5.56×45mm NATO bullpup assault rifle, designed by FN Herstal in Belgium. The F2000 made its debut in March 2001 at the IDEX defence exhibition held in Abu Dhabi, in the United Arab Emirates. The F2000 is a modular weapon system; its principal component is a compact 5.56×45mm NATO-caliber assault rifle configured in a bullpup layout. The F2000 is a selective fire weapon operating from a closed bolt. The rifle consists of two main assemblies: the barreled receiver group and the frame, coupled together by means of an axis pin located above the trigger guard. The barrel group has an integral MIL-STD-1913 Picatinny rail used to mount optical sights. The frame or lower receiver contains the trigger group, the bolt and bolt carrier assembly, return mechanism and magazine well. A removable handguard is installed in front of the trigger which completes and encloses the trigger guard.
VHS 2-(“multifunctional Croatian machine gun") is a 5.56×45mm NATO bullpup assault rifle designed and manufactured by HS Produkt of Croatia. The VHS rifle was first introduced at the 2007 iKA exhibition, the annual Croatian innovation display that takes place in the city of Karlovac. The development was carried on following a request from the Croatian Army for a new infantry rifle to update the individual equipment to NATO standards. The VHS-2 was shown to the public for the first time in April 2013, during the Adriatic Sea Defense & Aerospace (ASDA) exhibition in Split, Croatia. The new weapon is an improved version of the VHS rifle which retains its bullpup design, caliber and barrel length, as well as the internal mechanism, but introduces a new, more conventional fire selector, a redesigned carrying handle, an adjustable-length buttstock, and an ambidextrous cartridge casings ejection system that can be configured for either right or left side ejection in less than a minute
M4 CARBINE- is a shorter and lighter variant of the M16A2 assault rifle. The M4 is a 5.56×45mm NATO, air-cooled, direct impingement gas-operated, magazine-fed carbine. It has a 14.5 inch barrel and a telescoping stock. The M4 carbine is heavily used by the United States Armed Forces and is replacing the M16 rifle in most United States Army and United States Marine Corps combat units as the primary infantry weapon. The M4 is also capable of mounting the M203 grenade launcher. The distinctive step in their barrel is for mounting the M203 with the standard hardware. The M4 is capable of firing in semi-automatic and three-round burst, while the M4A1 is capable of firing in semi-auto and full automatic.

MSBS-5,56 Radon (Modular Firearm System 5.56mm Calibre - Radon) is an assault rifle currently under development as a future service rifle of the Polish Army. There are two basic variants currently being developed, based on a common upper receiver: a bullpup version and a standard version with folding, retractable stock. Thanks to a variety of modules, both variants can be easily transformed into a carbine, sniper rifle or squad light machine gun. Additionally, there exist plans to develop a 12-gauge combat shotgun based on the platform, as well as rifles in common Soviet calibers for export. MSBS-7,62 is the designation of the battle rifle variant of the MSBS platform that has entered the prototype phase, chambered for the full-power 7.62x51mm NATO rifle round, to be featured during MSPO in the Fall of 2016. Planned variations include a designated marksman rifle, a sniper support rifle, and a support weapon for deployment with parachute infantry.
HECKLER & KOCH G36-Created for the requirements of the German armed forces, the G36 continues to set the standard in the field of assault rifles. Used as an infantry weapon in a large number of countries, special forces and security forces also rely on its constant reliability. Essential components of the G36 are made of glass fibre reinforced plastic. This gives the user a lightweight weapon with high performance and low maintenance requirements. The G36 is ideally suited for dismounted infantry operations. For optimal handling, weight, and rate of fire in close-quarters battle, and for rapid, accurate and penetrating single fire in long-range combat. The G36 is a 5.56×45mm assault rifle, designed in the early 1990s by Heckler & Koch (H&K) in Germany as a replacement for the heavier 7.62mm G3 battle rifle. It was accepted into service with the Bundeswehr in 1995, replacing the G3. The G36 is gas-operated and feeds from a 30-round detachable box magazine or 100-round C-Mag drum magazine.
