The receiver is engraved "RAPID AIR WORX THEOBEN HM 1000X" and "MADE IN USA," reflecting the model's Theoben Rapid heritage and current U.S. manufacture. The chassis is black anodized aluminum with M-LOK interfaces and top Picatinny rail segments; catalog notes indicate a +20 MOA rail. This configuration provides a solid, modular foundation with clear, purposeful component choices.
The action is a fully regulated PCP with a right-hand straight-pull side-lever and a large cylindrical charging handle for smooth cycling. It feeds from a 12-round .25 caliber magazine and is equipped with a two-stage, match-grade, fully adjustable trigger to fine-tune the break to the shooter’s preference.
The 24-inch Lothar Walther barrel is carbon-fiber wrapped and tensioned, then shrouded with a reflex-type moderator and multi-port end cap. This combination emphasizes barrel rigidity and refined gas management within the shroud system.
Furniture includes an AR-compatible layout with an A*B Arms adjustable buttstock and cheek riser, plus an AR-style pistol grip for familiar ergonomics. The aluminum M-LOK forend supports accessory placement while keeping weight balanced. The length of pull is listed at 13.0 inches.
