The FBM assault rifle (Fusil Automatico FBM) is an assault rifle manufactured by FBM of Bolivia. The weapon was designed around the IMI Galil and the Stoner 63. The FBM was designed by Gordon Ingram and manufactured by Fabrica Boliviana de Municiones in the 1990s. It was designed for ease of cost/manufacture and with limited equipment such as lathes/mills etc. Although the design uses various combat proven design components, it is not known if the weapon was manufactured and if any more info is available.
The FBM assault rifle uses designs from the IMI Galil and the Stoner 63. It uses 5.56×45mm NATO (Galil/STANAG magazines) and 7.62×39mm M43 rounds (AK47 magazines) and exists in Rifle/Carbine/SMG layouts. Components are made from 4130 and 8620 chrome molybdenum heat treated alloy steel for durability. The bolt is enclosed in a one piece receiver attached to an inline barrel to the bore with the cocking handle at the rear to resist overheating. Weapon when fired using a roller hammer. Field stripping of the bolt is at the rear of the upper receiver allowing the secure low profile use of sights etc. low mounted on the receiver. The FBM also uses a fixed stock as well as FN/Galil side folding stock, bipod, bayonet, grenade launchers and electrical fire controls. Designed for ease of manufacture in facilities with limited equipment/resources, the basic structural components/lockwork are pressed sheet stampings with simplified outlines and contours for in house modular design. However, only the bolt and gas components are manufactured on lathes/mills.
The fire control group of the FBM has 3 positions: Forward position allows full auto, Middle allows semi auto, Rear allows safety. When field stripping, press down rear tab of the recoil spring guide at the rear of the upper receiver and hinge open forward (holding rear tab of the recoil spring guide). This would allow the recoil spring guide and bolt group to be removed from the upper receiver.
The IMI Galil is a family of Israeli-made automatic rifles chambered for the 5.56×45mm NATO and 7.62×51mm NATO cartridges. Originally designed by Yisrael Galili and Yakov Lior in the late 1960s, the Galil was first produced by the state-owned Israel Military Industries and is now exported by the privatized Israel Weapon Industries.
The Colt AR-15 is a lightweight, magazine-fed, gas-operated semi-automatic rifle. It is a semi-automatic version of the M16 rifle sold for the civilian and law enforcement markets in the United States. The AR in AR-15 stands for "ArmaLite Rifle", after the company that developed it in the 1950s. Colt's Manufacturing Company currently owns the AR-15 trademark for its line of semi-automatic AR-15 rifles.
The RK 62, officially 7.62 RK 62 and commercially M62, is an assault rifle manufactured by Valmet and Sako. It is the standard issue infantry weapon of the Finnish Defence Forces.
The Vektor R4 is a South African 5.56×45mm assault rifle. It entered service as the standard service rifle of the South African Defence Force (SADF) in 1980. In South African service, the R4 replaced the R1, a variant of the 7.62×51mm FN FAL. It was produced by Lyttelton Engineering Works, now Denel Land Systems.
The ArmaLite AR-18 is a gas-operated assault rifle chambered for 5.56×45mm NATO ammunition. The AR-18 was designed at ArmaLite in California by Arthur Miller, Eugene Stoner, George Sullivan, and Charles Dorchester in 1963 as an alternative to the Colt AR-15 design, a variant of which had just been selected by the U.S. military as the M16. A semi-automatic version known as the AR-180 was later produced for the civilian market. While the AR-18 was never adopted as the standard service rifle of any nation, its production license was sold to companies in Japan and the United Kingdom, and it is said to have influenced many later weapons such as the British SA80, the Singaporean SAR-80 and SR-88, the Belgian FN F2000, the Japanese Howa Type 89 and the German Heckler and Koch G36.
The Stoner 63 is a 5.56×45mm NATO modular weapon system. Using a variety of modular components, it can be configured as an assault rifle, carbine, top-fed light machine gun, belt-fed squad automatic weapon, or as a vehicle mounted weapon. Also known as the M63, XM22, XM23, XM207 or the Mk 23 Mod 0 machine gun, it was designed by Eugene Stoner in the early 1960s. Cadillac Gage was the primary manufacturer of the Stoner 63 during its history. The Stoner 63 saw very limited combat use by United States forces during the Vietnam War. A few were also sold to law enforcement agencies.
Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gas created by the ignition of the propellant charge.
The Z-M LR-300 is an American select-fire assault rifle designed by gunsmith Allan Zitta and manufactured by Z-M Weapons. The model name LR-300 stands for Light Rifle and 300 is for 300 meters, which is regarded by the manufacturer as the effective range of the rifle with a standard 55 gr (3.6 g) FMJ bullet. The design is based on the AR-15, M16 and C7 rifles, but has a unique semi-direct gas impingement system and a folding stock option.
The APS-95 was an assault rifle manufactured in Croatia by Končar-Arma d.o.o since 1995 and offered for export up to at least 2007. The manufacturing company, a subsidiary of the Croatian ARMA-GRUPA Corporation, has been manufacturing the ERO and Mini-ERO submachine guns since the mid-1990s.
The two most common assault rifles in the world are the Soviet AK-47 and the American M16. These Cold War-era rifles have been used in conflicts both large and small since the 1960s. They are used by military, police, security forces, revolutionaries, terrorists, criminals, and civilians alike and will most likely continue to be used for decades to come. As a result, they have been the subject of countless comparisons and endless debate.
The Sturmgewehr 57 is a selective fire battle rifle designed by Schweizerische Industrie Gesellschaft of Switzerland. The Stgw. 57 assault rifle uses a roller-delayed blowback system similar to the blowback system of the Heckler & Koch G3 and CETME rifles. As an assault rifle, the model AM 55 entered service in the Swiss Army in three designations F. ass. 57 7.5mm and 7.5mm Stgw. 57. Technologically, the Stgw. 57 was the mechanical and design basis for the export-variations of the SG 510 family of small arms. After thirty-three years, from 1957 to 1990, the Swiss Army replaced the Stgw. 57 with the SIG SG 550, a lighter-weight assault rifle.
AMD-65 is a Hungarian-manufactured licensed variant of the venerable selective fire AKM rifle for use by that nation's armored infantry and paratrooper ("descent") units within the Hungarian Defence Forces. The rifle's design is suited for outdoor use as an infantry rifle but can also be used from within the confines of an armored vehicle as a fire support weapon. This is possible due to the side-folding stock of shaft design that makes it more compact. The 12.6-inch barrel is also relatively short for the 7.62×39mm cartridge. The operating mechanism does not require a gas expansion chamber at the muzzle, as in the AKS-74U to ensure reliable functioning, but does use a specially designed muzzle brake.
The Claridge Hi-Tec and its antecedent the Goncz High-Tech Long Pistol are semi-automatic pistols designed by Hungarian inventor Lajos John Goncz. This unique firearm features a telescopic bolt design encased in a tubular upper receiver with a forged steel frame, button rifled match barrels, and 16-round magazines standard.

The CETME Model L is a Spanish 5.56×45mm NATO assault rifle developed in the late 1970s at the state-owned small arms research and development establishment CETME located in Madrid. The rifle retains many of the proven design elements the institute had used previously in its CETME Model 58 battle rifles.
The SG 540 is a 5.56×45mm NATO assault rifle developed in the early 1970s by Schweizerische Industrie Gesellschaft of Neuhausen, Switzerland as a private venture primarily destined for export markets and as a potential replacement for the 7.5×55mm Swiss SG 510 automatic rifle known as the Stgw 57 in Swiss service.
The IWI Galil ACE, also marketed as IWI ACE, is a series of assault rifles and battle rifles originally developed and manufactured by Israel Weapon Industries (IWI). It is produced in three different calibres: 5.56×45mm NATO, 7.62×39mm and 7.62×51mm NATO.
The PSL is a Romanian designated marksman rifle. It is also called PSL-54C, Romak III, FPK and SSG-97. Though similar in appearance, mission and specifications to the SVD Dragunov, the PSL rifle is mechanically completely different as it is based on the RPK light machinegun, with its internals simply being scaled up to accommodate the more powerful 7.62×54mmR cartridge.
An AR-15–style rifle is a lightweight semi-automatic rifle based on or similar to the Colt AR-15 design. The Colt model removed the selective fire feature of its predecessor, the original ArmaLite AR-15, itself a scaled-down derivative of the AR-10 design by Eugene Stoner. It is closely related to the military M16 rifle.
The FFV 890 was a Swedish assault rifle manufactured and designed by Försvarets Fabriksverk. The FFV 890 was based on the IMI Galil through a manufacturing licence, which in turn was based on the Finnish Valmet RK 62 and ultimately the Soviet AK-47. The FFV 890 was designed between 1975 and 1980, and its final iteration, FFV 890C, competed in the Swedish Armed Forces trials for the new 5.56×45mm NATO assault rifle, where it ended up as a runner-up to the FN FNC, which was then chosen as the Ak 5. The FFV 890C was never widely adopted by any service, though some rifles were used by the Swedish police.
