Overview

The MKEK MPT-55 is a Turkish select-fire assault rifle chambered in 5.56x45mm NATO, introduced in 2017 as the 5.56mm caliber variant of the MPT-76 platform. Developed by Makina ve Kimya Endüstrisi Kurumu (MKEK) as part of Turkey's Milli Piyade Tüfeği (National Infantry Rifle) program, the MPT-55 represents Turkey's effort to replace its license-produced Heckler & Koch HK416 rifles with domestically manufactured equivalents. The rifle uses a short-stroke gas piston operating system, a rotating bolt, and accepts standard NATO STANAG magazines. Featuring full ambidextrous controls, a telescoping buttstock, and a Picatinny rail system, the MPT-55 was designed for Turkish Special Forces and elite military units operating across diverse environments - from Mediterranean coastal regions to high-altitude mountain warfare in eastern Anatolia.

Notes

The MPT-55 was officially unveiled at IDEF 2017 alongside the MPT-55K (carbine variant with 280mm barrel) and MPT-55SK (compact). Turkey planned an initial procurement of 20,000 rifles to replace HK416s within Special Forces. The MPT-55 shares approximately 80% parts commonality with the MPT-76 platform. Designed to NATO interoperability standards including standard STANAG magazine compatibility.

Background

The MPT-55 was first publicly fielded by the Turkish Presidential Guard in 2018 as a symbol of Turkey's growing defense industry self-sufficiency, deliberately replacing the German-designed HK416 rifles previously carried by the unit during state ceremonies. Despite outward similarities to the AR-15/HK416 family, MKEK engineers redesigned key internal components to reduce dependency on foreign suppliers - part of a broader Turkish defense doctrine pushing for indigenous small arms after decades of license production.
