Tokyo Marui Hi-Capa 5.1 D.O.R. (Direct Optics Ready) black / chrome , a premium gas blowback (GBB) pistol designed for competitive shooting and IPSC drills.

Key Performance Features
Direct Optics Ready (D.O.R.) System: The slide is specifically pre-cut to mount micro red dot sights, such as the Tokyo Marui Micro Pro Sight. It includes both low-profile and high-profile mounting plates in the box.
Enhanced Blowback Engine: According to Land Warrior Airsoft, it utilizes a newly engineered blowback engine with a larger gas cylinder and a short recoil system derived from the M45A1 model for improved stability and faster cycle times.
Specialized Controls: It features a flat-faced short trigger for precise control and a semi-long slide stop for easier manipulation during fast-paced matches.
Durability Reinforcements: To protect the polymer slide, Tokyo Marui has integrated a metal notch spacer that absorbs the stress of the slide locking back, preventing wear over time.
