The round, vented rifle-length handguards are secured by a delta ring, and the fixed stock includes a trapdoor buttplate and rear sling loop with a 13.0 in length of pull. An A2 pistol grip completes the classic pattern.
The flat-top upper provides a Picatinny rail and retains core AR features such as a forward assist, case deflector, and ejection port cover. Iron sights are set up with an F-marked front sight base and an A2-style rear sight in the detachable carry handle. The rifle accepts STANAG-pattern magazines and is listed with a 20+1 capacity.

Thoughtful, user-focused touches include the installed GG&G single-point sling plate for streamlined sling mounting. The combination of correct sighting system, rifle-length components, and period-correct furniture underscores the rifle’s intent as a faithful M16-style clone.
