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.

Design

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.

<span class="mw-page-title-main">Comparison of the AK-47 and M16</span> Comparison of two notorious assault rifles

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 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.
