The Argentum was born for CQB. Its silver finish and compact profile make it an immediately identifiable replica, but it's under the hood that everything happens: every component has been selected to lighten the overall weight, improve mechanical reliability, and make shooting responsive in confined spaces.

FUKU-2 Skeleton CNC Upper: light and rigid

The CTM Tactical FUKU-2 Skeleton upper in CNC aluminum features a skeletonized structure that reduces weight without sacrificing rigidity. The silver anodized finish resists daily wear and gives the Argentum its visual identity.

CTM TAC FUKU-2 CNC Compensator

The CTM TAC FUKU-2 CNC compensator follows the upper's design: same finish, same CNC manufacturing. It helps control muzzle rise with every shot.

CTM FUKU-2 Nylon Frame

The CTM FUKU-2 reinforced nylon frame retains the original mounting points and maintains compatibility with carbine or SMG conversions.

CTM Adjustable Trigger: a crisp break

The CTM Tac adjustable trigger reduces pre-travel. In close-quarters CQB engagements, less travel means a crisper break and a more fluid firing rate.

TTI Hammer Kit: long-term reliability

The complete TTI hammer kit replaces the most fragile component of the standard AAP-01. Our article on the broken hammerexplains why it fails on a standard base – with the Argentum, the problem is solved by default.

CTM 160% and 200% Springs: optimized operation

The CTM 160% non-linear recoil spring (piano wire) improves cycling even in cold weather. The CTM 200% nozzle spring ensures a crisp cycle and consistent pressure shot after shot.

Decepticon 60° Hop-Up Bucking + 6.03 Barrel: stable trajectory

The Decepticon 60° bucking ensures consistent lift on each BB. Combined with the 6.03 inner barrel and careful alignment in the workshop, it provides stable trajectories. Our hop-up adjustment guidehelps you fine-tune the setting according to your BBs.

Assembled and adjusted by the BDU Custom Lab

Like every build in our range, the Argentum goes through our Custom Lab methodologybefore shipping: parts assembly, hop-up adjustment, ballistic control with a chrono. It's shipped adjusted for indoor fields, ready to play.

The Argentum in CQB

Compact, lightweight, reactive: the Argentum is designed for enclosed environments. The skeleton upper reduces fatigue during prolonged handling, the adjusted trigger speeds up shot response, and the silver finish clearly distinguishes it on the field.
