RetroArms CNC Aluminium Receiver SR-25

Highly precise and durable CNC body (receiver) from the Czech company RetroArms introduces uncompromising quality and innovation to the world of airsoft. Drawing inspiration from the manufacturing processes of real AR15 (M4/16) and AR10 (SR-25) firearms, this body is crafted from aircraft-grade duralumin EN AW 7075 T651, meaning it not only resists much harsher treatment than typical metal alloy bodies but also has a significantly longer lifespan.
This quality is achieved through an intricate CNC manufacturing process, requiring not only time but also a substantial amount of specialized material.

On the Upper (upper part of the body) of this body, you will find a precisely milled MIL-STD-1913 RIS rail and the option to use the original or a custom charging handle. Brass deflector and Forward Assist Button are part of the Upper, ensuring maximum strength and durability. For easy access to the Hop-Up chamber pressure adjustment, a practical dust cover on the spring is provided. The charging handle does not function to open the dust cover, but is purely decorative. The cover is manually opened with fingers.
Lower (lower part of the body) is also made from aircraft-grade duralumin EN AW 7075 T651 and is significantly reinforced, preventing it from breaking. Wedge pins connecting the Lower and Upper eliminate all gaps and play, typical for zinc bodies. The special wedge system ensures a solid connection without the need for excessive force.
The surface of the CNC body is sandblasted with synthetic corundum and protected by anodizing, preventing corrosion and giving the body a matte finish.

With this body from RetroArms, you not only gain high quality and durability, but also the possibility of individual customization for your airsoft weapon.
Installation requires expertise, but considering compatibility with Tokyo Marui standard, a smooth installation can be expected.
For the best results and ease of installation use it with a CNC RetroArms gearbox!

• CNC wedge pins with screws (2 pcs)
• CNC stock mounting plate with 4 screws
• CNC gearbox centre pin with screws
• CNC Forward Assist Button with spring and pin
• Plastic dust cover with spring and shaft

To complete the body, you will need the following parts:

• Fire selector switch
• Spring and ball for the fire selector switch (if not included with the switch)
• Right side fire selector switch cover (if you don't have an ambidextrous switch)
• Charging handle (you can use short version for M4/16)
• Spring and screw for the charging handle
• Bolt catch (imitation)
• Magazine catch (release)

When installing the gearbox, never use excessive force. When tightening screws, use a torque wrench with a maximum torque of 1Nm, as exceeding this can lead to the key turning in the screw head.
There is no need to tighten the screws excessively! For added assurance that the screws will not loosen, use thread-locking adhesive (threadlocker).
