M40A3 Sportline — 6mm Spring-Powered Airsoft Sniper (Black)
The M40A3 Sportline is a full‑scale, officially licensed replica inspired by the US Marine Corps sniper platform — built for players who want authentic handling and field‑ready versatility. Its polymer body is strengthened where it counts, with a metal barrel and receiver, engraved realistic markings and a textured grip that give this rifle a convincing weight and feel without the heaviness of real steel. The black finish keeps the look tactical and discreet on the field.
Ergonomics are a highlight: an adjustable cheek pad and length‑adjustable stock let shooters dial in a perfect eye‑to‑optic alignment, while the top 20mm rail and shorter lower rail accept scopes, bipods and other aiming accessories. Multiple QD sling points and a bipod adapter make the M40A3 fast to deploy and comfortable to carry during long ops or recon runs.
This variant is spring‑powered and tuned for performance — delivering approximately 1.9 joules (≈445 FPS with a 0.20 g BB) with a very smooth, easy cocking action that encourages quick follow‑up shots. The full‑metal bolt system and adjustable hop‑up mean the Sportline isn’t just a statue-piece: it’s a practical sniper rifle for skirmish play, target practice, or serious milsim use.
Durability and practical details round out the package: interchangeable sling points, a tapered barrel for improved ballistics, and a reliable 27‑round magazine (standard) keep you in the fight. With McMillan and ASG licensing, the M40A3 Sportline is equally at home on the range or in a collection.
