Complete custom Hi-Capa: reinforced hammer assembly and HPA feed

The custom hi-capaSLEEPER PRO takes everything from the SLEEPER PLUS—CNC hop-up chamber, reinforced nozzle and springs, adjustable trigger—and finishes the job on three points: the percussion, the feed, and the grip.

Reinforced hammer and slide guide

The hammer absorbs every shot: it is a known wear part on the Hi-Capa. The reinforced hammerlasts over time, and the slide guide allows for a more consistent slide cycle. Both are installed and tuned with the rest of the internals.

HPA feeding via M4 magazine

The M4 magazine adapterallows the replica to be powered by HPA via a line connected to a tank with a regulator. The pressure is no longer dependent on the outside temperature, and the replica uses M4-style magazines. The line and regulator are offered as options at checkout. Some fields regulate the use of HPA: check before playing.

Matched hop-up bucking and advanced tuning

On the PRO, the hop-up bucking is selected and adjusted according to the installed barrel, then the entire unit undergoes advanced pneumatic tuning and a chrono test. The textured grip panels of the M4 adapter replace the grips of the SLEEPER PLUS and maintain a firm hold, even when wearing gloves.

Percussion: hi-capa reinforced hammer

Power supply: HPA adapter for M4 magazine

TheM4 magazine HPA adapterchanges how the replica is powered. Instead of gas stored in the magazine, air is supplied via a line connected to a tank with a regulator: the pressure remains stable regardless of the temperature. The replica uses M4-type magazines. The HPA line and regulator are available as options when ordering, and some fields regulate the use of HPA with specific rules.

Fine adjustment: seal matched to the barrel

The barrel-matched buckingis selected and fitted specifically to the installed barrel, rather than using a standard bucking. This is what allows the advanced pneumatic tuning of the SLEEPER PRO to be fully effective: our workshop adjusts the hop-up, tests the cycling, and chronographs the replica before shipping.

Custom Lab F.A.Q.

Lead times vary depending on the complexity of the project. Generally, allow between 2 weeks for a standard pre-build replica, and up to 4 weeks for a full conversion with custom modifications.

Yes, we ship throughout Europe. Shipping costs are calculated automatically based on your destination. Standard delivery time: 3-7 business days after dispatch.

On new replicas only, never refurbished: Action Army for the AAP-01, Tokyo Marui for the Hi-Capa. Each build is assembled, tuned, and chronographed before shipping.

All original parts removed during the conversion will be returned to you upon request, in addition to your replica, carefully packaged and labeled.
