TAPP HYBRID GHK G5 Carbon Fiber Lower Receiver Details

TAPP HYBRID GHK G5 Lower Receiver

The TAPP HYBRID GHK G5 Lower Receiver is a revolutionary upgrade for your GHK G5, combining the ease of High Pressure Air (HPA) and the reliability of AEG MP5, ARP9, or EVO magazines with the exhilarating recoil of a Gas Blow Back (GBB) rifle. By replacing the entire lower receiver, this adapter allows you to use these AEG magazines in your G5, bringing new functionality and flexibility.
EVO magazines feature a BB follower that activates a mag catch when empty, offering a unique reload experience not available with most HPA adapters. Note: MP5 and ARP9 options do not have a bolt catch feature.
Designed and built in the USA, this reinforced lower receiver is ready for intense action, delivering consistent performance with every shot.

Production Time: This lower has a 1-2 week production time depending on if you choose the FCG Add-on or Cerakote.

Key Features:

    • AEG MP5, ARP9, or EVO Magazine Compatibility: Adapt your GHK G5 to use a variety of AEG magazines. EVO mags include a BB follower for Bolt Stop activation, enhancing realism. (MP5/ARP9 do not include this feature. )
    • HPA Powered: Optimized for 150 max, recommended PSI: 150 max, recommended 120, this lower receiver ensures consistent performance, allowing you to enjoy the reliability of HPA without sacrificing the GBB feel
      (HPA kit available separately at tappairsoft. com/hpa).
    • Reinforced Lower Design: Built to handle the G5’s robust recoil, maintaining durability under intense gameplay.
    • One-Piece, Plug-and-Play Installation: Fully assembled (with FCG add-on) and ready to use, with no modifications required.
    • Durable Construction: Crafted from lightweight, tough SLS Nylon PA11 Carbon Fiber, designed to withstand rigorous action while maintaining a sleek, low-profile look.
    • Burst Disc: A burst disc is included to prevent damage from accidental over-pressurization.

What’s Included:

    • Fully Assembled Lower Receiver: The TAPP HYBRID GHK G5 Lower Receiver is ready to install, available with or without the Fire Control Group.
    • HPA Foster Fitting (US Spec): Compatible with most Airsoft HPA lines.
    • Additional Feedlip: Easily replace the feedlip with four screws in case of breakage or wear.
    • Pistol Grip Hose Template: Helps with drilling the hole in the pistol grip to route the HPA line.
    • Sorbo Pad: Install this on the back of the bolt carrier backplate to help absorb recoil.
    • FCG Install Pin: A handy tool to assist with installation of the Fire Control Group.
    • Stock Adapters (AEG Spec & Picatinny): Includes both adapter styles for compatibility with AEG buffer tubes and Picatinny-mounted stocks or braces.

Strength you can feel. Weight you barely notice. Precision that defines performance.
Matte black, rigid, and ready — engineered for those who demand more than plastic.

Unmatched Strength and Rigidity

Up to 38% Higher Tensile Strength – 69 MPa vs. 50 MPa for Nylon 12, giving parts more load-bearing capability.
Nearly 3× Stiffer – With a tensile modulus of 5.3 GPa (vs. 1.9 GPa), PA11 CF parts hold their shape under pressure and stress.
Over 65% Greater Flexural Strength – 110 MPa vs. 66 MPa for Nylon 12 means stronger parts that won’t bend or deform.

Superior Heat and Environmental Resistance

Designed for high-temperature applications where Nylon 12 softens or degrades.
Carbon fiber reinforcement improves thermal stability and lowers thermal expansion for precision even under heat.
Naturally resistant to moisture and UV exposure, ideal for rigorous outdoor use.

Professional Finish and Lightweight Design

Carbon fiber infusion produces a sleek matte black surface — functional and aesthetic right off the printer.
Delivers metal-like strength at a fraction of the weight, enabling lighter, more efficient assemblies.

Designed for High-Pressure HPA systems

Lightweight carbon fiber composite reduces load without sacrificing strength or rigidity.
Tested for durability across extreme temperature and humidity conditions to ensure reliable field performance.

Rigid Carbon Fiber Structure

Low expansion under heat preserves airseal integrity during rapid-fire or sustained full-auto use.
Machined precision surfaces ensure smooth magazine insertion and consistent alignment with feed paths.

Advanced Finishing

Custom Cerakote & Precision Coatings

Our in-house finishing delivers Cerakote and precision laser engraving with exceptional durability and style. Every surface is treated, coated, and inspected to ensure flawless performance and lasting quality.

  1. james.pendlebury (verified owner)

    An excellent lower with amazing build quality. It’s worked flawlessly and used about 500 psi per 10 mags in 0c weather and survived being dragged through soupy mud on a game day. One issue I did have was the inner wall to the rear takedown pin ruptured. No effect on the takedown pin detent but it does show off the spring now. It was supplied with everything needed for easy assembly which included a printed adapter to drill into my own pistol grip to feed the hpa line through. Highly recomend to anyone on the fence, the creator is an amazing person who is welcome to feedback and recomendations
