Real Deal AOE Spacer - Nylon
Key Features:
-
Perfect AOE Correction:
- Provides an evenly distributed barrier over the entire face of the piston.
- Prevents forward movement of the piston rack (not required for Real Deal pistons).
-
Centered Piston Head Alignment:
- Snug fit around piston head set screw threads ensures proper centering during installation.
-
Lightweight Design:
- Weighs only 0.03 grams to minimize added weight in fast-cycling gearboxes.
-
Improved Angle of Engagement (AOE):
- Allows the sector gear to pick up the piston closer to the 12 o'clock position.
- Reduces system stress and prevents premature engagement (PME).
-
Customizable Fit:
- Use 1 or more spacers to achieve the ideal AOE depending on your gearbox setup.
How It Works:
- What is AOE? The Angle of Engagement (AOE) is the point where the sector gear picks up the piston assembly. Proper AOE reduces stress and ensures efficient cycling.
-
Why Use Real Deal Spacers?
- They adjust the piston’s position to improve engagement with the sector gear.
- Real Deal pistons have pre-cut teeth to naturally avoid premature engagement, but AOE correction is still advised for most builds.
Installation Tips:
-
Start with One Spacer:
- Insert one spacer and inspect the AOE.
- Ensure the sector gear engages closer to the 12 o’clock position.
-
Add Additional Spacers if Necessary:
- If the sector gear engages at the 1-2 o’clock position or shows signs of PME, add another spacer.
-
Check for Clearance:
- Verify that the piston teeth clear the sector gear and there’s no risk of PME.
Compatibility:
- Suitable for most AEG builds requiring AOE correction.
- Not required for Real Deal Piston Assemblies, which are pre-fitted with AOE washers and drop-in ready.
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.
