M3A1 Grease Gun

The Uzi is a family of Israeli open-bolt blowback-operated submachine guns designed by Uziel Gal in the late 1940s. One of the most recognizable firearms in the world, it has been adopted by military and law enforcement agencies in over 90 countries.

The Agram 2000 is a compact, selective-fire submachine gun designed and manufactured by RH-Alan (formerly Alan Arms) of Croatia. Its primary design philosophy centers on concealability and close-quarters combat (CQB) effectiveness, making it suitable for military special forces, law enforcement, and personal defense roles. The weapon is distinguished by its extremely compact size, achieved through a telescoping bolt design that allows the magazine to be housed within the pistol grip, similar to the Uzi and MAC-10. Key innovations include a simple blowback operation with a fixed firing pin, a side-folding metal stock for reduced carry profile, and a high rate of fire (approximately 800-900 rounds per minute) that enhances suppressive capability in close engagements. The Agram 2000 is known for its rugged reliability and ease of maintenance, though its accuracy is limited by its short barrel and open-bolt design. It has a reputation as a cost-effective, no-frills submachine gun, often compared to the Croatian-made Šokac and the Israeli Uzi. Notable design characteristics include a manual safety selector (safe/semi-auto/full-auto), a threaded barrel for suppressors, and a simple rear aperture sight. Its compactness and firepower have made it a niche choice for specialized units and private security contractors.

The M3 is a .45 ACP submachine gun developed by the United States during World War II as a cheaper, faster-to-produce alternative to the Thompson submachine gun. Its distinctive appearance earned it the nickname 'Grease Gun.'
