The MR. HOP UP SILICONE hop-up bucking from Maple Leaf is an upgrade component designed to improve the performance of electric airsoft replicas (AEGs), particularly in terms of range and accuracy.
Main Features:
- Material: Made of silicone, which maintains its elasticity and performance even at low temperatures, preventing the "Cold-Bore Shot" effect (the first shot that comes out with a different trajectory due to the hardening of the traditional bucking).
- Large contact surface: The internal contact surface is wider and larger than traditional buckings, offering optimal rotation of the BB. This makes it ideal for use with heavy BBs.
- Internal sealing ring: The bucking is equipped with a special ring on the inner surface of the collar. This ring ensures a perfect seal between the bucking and the air nozzle.
- Barrel Compatibility: Important: The barrel on which the bucking will be mounted must have a circular groove (standard) around the hop-up window to accommodate the internal sealing ring. Carefully check compatibility with your barrel before purchasing. It is compatible with Maple Leaf, SLONG barrels and others with a groove.
- Compatibility: AEG
Technical Specifications:
- Type: Hop-up bucking ("MR. HOP UP")
- Material: Silicone
- Features: Large contact surface, internal sealing ring
- Brand: Maple Leaf
- Compatibility: AEG replicas with barrels with circular groove (e.g. Maple Leaf, SLONG)
Advantages:
- Made of silicone for consistent performance at low temperatures (no "Cold-Bore Shot")
- Large contact surface for optimal BB rotation (ideal for heavy BBs)
- Internal sealing ring for a perfect seal with the air nozzle
- Improves range and accuracy
- Suitable for Sniper Rifles and DMRs
| Hardness (Degrees) | ROF (Recommended) | Temperature (Recommended) | Pros | Cons |
|---|---|---|---|---|
| Note: The hardness of the hop-up bucking is directly proportional to the ROF and operating temperature. A softer bucking is better at low ROF and low temperatures, a harder one at high ROF and high temperatures. Finding the "perfect" bucking for every situation can be complex. If in doubt, our technician is available. | ||||
| 50° | Low-Medium | Low | Maximum grip, excellent hop-up effect with light BBs | Rapid wear, less suitable for high ROF/heavy BBs |
| 60° | Medium | Low-Medium | Excellent grip, good performance/durability compromise | Faster wear than hard buckings, less suitable for high ROF |
| 70° | Medium-High | Medium-High | Good durability, suitable for standard/upgraded configurations | Requires more hop-up pressure, less effective at low temperatures |
| 75° | High | Medium-High | Excellent durability, suitable for upgraded configurations and high ROF | Requires more pressure, less effective in the cold |
| 80° | Very High | High | Maximum durability, suitable for extreme configurations | Requires a lot of pressure, less effective in the cold |
