CNC Skeletonized AR15 Receiver – Type C New Gen

Upgrade your AR15 (M4) replica with a lightweight, durable, and precision-engineered CNC receiver. Unlike standard casted alloy models, this aircraft-grade aluminum (EN AW 7075 T651) receiver delivers exceptional strength and resilience. Thanks to its skeletonized design, it reduces weight while maintaining structural integrity.

Key Features

  • High-Strength Aluminum – Constructed from solid EN AW 7075 T651 aluminum, this receiver boasts an impressive 590MPa tensile strength, surpassing common construction steel (390MPa).
  • Lightweight & Resilient – The skeletonized build minimizes weight without sacrificing durability. Tested in various conditions, it effectively resists dirt and debris.

Precision Upper Receiver

  • Milled RIS Rail (MIL-STD-1913) ensures secure mounting for optics.
  • A fully integrated shell deflector and forward assist pin, machined from a single aluminum block, enhances durability.
  • The spring-mounted dust cover provides effortless Hop-Up access while maintaining a secure seal.
  • Designed for compatibility with Tokyo Marui standard handguards and outer barrels, allowing easy upgrades.

Reinforced Lower Receiver

  • One-piece construction increases overall strength and longevity.
  • More space for wiring improves cable management, making installation easier.
  • Pre-milled rubber pads absorb vibrations, eliminating unwanted metal-on-metal noise.
  • To ensure a tight, gap-free fit, special wedge pins lock the receiver securely in place.

Seamless Compatibility & Customization

  • Designed for CNC Split Gearbox or CNC Gearbox V2 – Third-party compatibility may vary.
  • Works with AR15 (M4) stocks and handgrips that follow Tokyo Marui standards.
  • Fully customizable – Fire selector, magazine catch, and bolt catch can be replaced with aftermarket CNC parts.
  • Stock Adaptor Included – Supports QD adaptors for strap mounts, providing flexibility in customization.

Premium Finish & Protection

  • Matte sandblasted surface – Treated with synthetic corundum, ensuring a sleek, non-reflective appearance.
  • Hard-anodized coating – A specialized anodizing process protects against corrosion and wear.

Common Product Questions

Find quick answers about our airsoft products, shipping and policies.

Will this part fit my platform?

Compatibility is product-specific. Check the brand, model, size, and platform named in the product description, such as Tokyo Marui Hi-Capa 4.3 or 5.1, AAP-01, Umarex/VFC Glock, or a particular AEG gearbox type.

Similar-looking parts are not always interchangeable, so contact our team with your exact model if you are unsure.

Do I need tools or gunsmithing?

That depends on the upgrade. Simple external parts may be straightforward, but internal upgrades can require disassembly, reassembly, adjustment and testing.

If you are not comfortable working inside your airsoft gun, our team offers professional tech and custom-build services.

Can LA Airsoft install this part for me?

Yes. We can build and upgrade Hi-Capas, AAP platforms, and rifles. Choose your base gun and parts, then add the appropriate tech service.

The current custom-build service states that builds are normally completed in approximately 3 to 5 days, with the team reviewing the selected parts for compatibility.

How should I maintain this product?

Regular maintenance helps preserve performance and reliability. Keep the product clean, follow the manufacturer’s lubrication instructions, and properly manage batteries, gas systems, and internal components. More advanced repairs or internal servicing should be handled by an experienced airsoft technician.

How quickly will my order ship?

Orders without preorder items are typically packed the same day when placed before 4:30 p.m. Central Time. Please note that occasional delays can occur during especially busy periods or when staffing is limited.

Will this part increase my FPS?

Not every upgrade increases FPS. Some parts are designed primarily for reliability, cycling speed, weight reduction, or gas efficiency. When a product has a tested FPS claim, it should be stated in the listing.
