AK-105

A civilian AK variant known for its versatility and legality in various markets.

The M4A1 is a fully automatic, gas‑operated carbine derived from the Colt M16A2 rifle, designed to provide a lightweight, compact fire‑arm for close‑quarters combat while retaining the 5.56×45mm NATO cartridge performance of its parent platform. Developed primarily for U.S. military special operations and later adopted by conventional forces, the M4A1 features a 14.5‑inch (368 mm) barrel, a collapsible four‑position stock, and a flat‑top receiver with a Picatinny rail for modular accessory attachment. Its distinguishing innovations include a full‑auto only fire‑mode (no three‑round burst), a hardened steel bolt and barrel extension for increased durability, and a cold‑hammer‑forged barrel with a 1:7 twist rate optimized for modern ammunition. The carbine’s reputation rests on its reliability, ergonomics, and adaptability, making it a benchmark for modern assault rifles and a favorite among military, law‑enforcement, and civilian shooters seeking a proven, modular platform.

The AK-47 (Avtomat Kalashnikova model 1947) is a gas‑operated, selective‑fire assault rifle designed around a simple, rugged construction philosophy that prioritises reliability under adverse conditions over ergonomic refinement. Intended primarily for military service, it has also been adopted by numerous law‑enforcement and paramilitary groups, and civilian semi‑automatic variants are widespread. Its key innovations include a long‑stroke gas piston with a rotating bolt, a chrome‑lined barrel and chamber, and a stamped or milled receiver that can be produced with minimal tooling. The AK‑47’s reputation rests on its legendary durability, ease of maintenance, and ability to function with dirty ammunition, which has made it the archetype of a “battle‑ready” weapon. Distinguishing characteristics are its distinctive curved 30‑round magazine, pronounced recoil spring guide rod, and the iconic wooden or polymer stock with a pistol grip that together create a silhouette recognized worldwide.
