R-Guns TRR-15 5.45x39mm – AR-15 Pattern Rifle with OD Green Furniture

Offered for sale is an R-Guns TRR-15 semi-automatic rifle chambered in 5.45x39mm, featuring an AR-15-pattern design with distinctive OD green furniture and a mounted optic.

While most AR-15 rifles are chambered in 5.56 NATO or .223 Remington, this TRR-15 is chambered for the 5.45x39mm cartridge, originally developed for the Soviet AK-74 military rifle.

This less common chambering gives the rifle a distinctive place among commercially produced AR-pattern firearms.

The rifle pictured features a black receiver, OD green adjustable stock, matching pistol grip and ventilated handguard, and a mounted red-dot-style optic.

The Unusual 5.45x39mm AR-15 Platform

The 5.45x39mm cartridge was introduced by the Soviet Union during the 1970s as the standard cartridge for the AK-74 rifle.

Although commonly associated with Eastern European AK-pattern firearms, 5.45x39mm has also been used in American AR-15-pattern rifles.

These rifles combine the familiar ergonomics and controls of the AR-15 platform with a cartridge more commonly encountered in AK-74 rifles.

The R-Guns TRR-15 represents one of these less common AR-pattern configurations.

OD Green Furniture and Modern AR Configuration

This particular TRR-15 features a combination of black metal components and OD green furniture.

The rifle is equipped with an adjustable stock, matching pistol grip, and ventilated free-float-style handguard.

The handguard features multiple ventilation slots and a top Picatinny rail extending toward the receiver.

The overall configuration gives the rifle a distinctive appearance compared with traditional black AR-15 rifles.

Mounted Optic

A red-dot-style optic is mounted above the receiver on a raised mounting assembly.

The optic provides an alternative sighting arrangement to traditional iron sights.

The exact optic manufacturer, model, and operational condition have not been independently verified.

The optic shown in the photographs is included with the rifle.

Distinctive Barrel Configuration

This TRR-15 features a long exposed barrel extending forward of the OD green handguard.

A cylindrical muzzle device is installed at the end of the barrel.

The exact barrel length, barrel manufacturer, twist rate, and muzzle-device specifications have not been independently verified.
