EMG / KelTec Licensed RDB17 Airsoft Bullpup AEG Rifle – Innovative Bullpup Power in a Compact Design

The EMG / KelTec RDB17 Airsoft AEG is a game-changing bullpup rifle designed for serious airsoft enthusiasts looking for compact firepower, cutting-edge ergonomics, and ambidextrous performance. Fully licensed by KelTec and built in collaboration with ARES, this airsoft replica mirrors the real-steel RDB17’s distinctive downward-ejecting system, giving left- and right-handed shooters a hassle-free experience without compromising realism or functionality.

Crafted with a durable nylon fiber outer body and reinforced by a metal outer barrel and gas assembly, the RDB17 is both lightweight and rugged—ready for your next milsim op or urban CQB scenario. The combination of realistic weight, authentic KelTec trademarks, and sleek bullpup engineering makes this rifle a standout addition to any loadout.

True Innovation: Downward Ejection System

One of the RDB17’s most notable features is its downward brass ejection design, a signature trait of the real KelTec rifle. While most bullpups struggle with casing ejection that can interfere with left-handed shooters, this model elegantly solves the problem. EMG has faithfully replicated this function in spirit by ensuring the design favors ambidextrous use—whether you're a righty, a lefty, or switching shoulders mid-game.

EFCS Gearbox & MOSFET for Superior Trigger Response

At the heart of this AEG is a reinforced metal gearbox, upgraded with ARES’ EFCS (Electronic Firing Control System). This includes a microswitch trigger, built-in MOSFET, LiPo compatibility, and programmable firing modes, giving you a crisp, fast trigger response and improved battery efficiency. Need to tune your FPS for field limits? The quick-change spring system has you covered—no need to disassemble the rifle.

Precision & Modularity Built In

With an inner barrel length of approximately 445mm, the RDB17 offers impressive accuracy, even in its compact 695mm overall length. It’s ideal for tight corners, buildings, and close-quarter engagements—but still hits hard with an FPS range of 390–420, right out of the box.

The upper receiver features a full-length 20mm Picatinny rail, perfect for mounting optics or red dots. The lower handguard also includes rail segments, giving you room to attach foregrips, bipods, lights, or lasers to suit your playstyle. Plus, the spacious handguard battery compartment supports an 11.1v LiPo Butterfly, wired to Deans for high efficiency and minimal resistance.

Enhanced Usability & Compatibility

This rifle comes with two mid-cap magazines (~130rd and ~100rd), and it's compatible with a wide range of M4/M16 AEG mags, including Matrix, Tokyo Marui, and G&P. With ambidextrous fire selector and magazine release, left-handed users can fully operate the rifle without modification. The rotary-style adjustable hop-up lets you fine-tune your trajectory for different BB weights or field conditions.

KelTec & EMG – Licensed Excellence

As with all EMG licensed products, the RDB17 is crafted with input from the real firearms manufacturer, KelTec, delivering a faithful 1:1 scale replica. Every line, contour, and marking is true to the original, making this not just a competitive tool, but also a collectible centerpiece.

Whether you're in search of an advanced CQB rifle, a modern bullpup design, or simply a unique addition to your armory, the EMG RDB17 delivers innovation, quality, and performance—without compromise.
