PTS MEC Hop Up (AEG version) (2pack) - Black+Purple

Eliminate compression losses and erratic groupings with the PTS MEC Hop Up Bucking (AEG Version) 2-Pack. Crafted specifically for the demands of modern high-performance Automatic Electric Guns, this twin-pack upgrade addresses the primary bottlenecks found in standard factory hop-up configurations.

Symmetrical Dual-Point Contact Patch The core performance advancement of the MEC AEG rubber lies within its unique inner geometry. Rather than utilizing a traditional flat or single-point mound, it features an engineered dual-point contact patch. When the hop-up arm applies downward force, these twin pressure points press identically onto both upper sides of the BB simultaneously. This action centers the projectile perfectly down the center axis of your inner barrel, generating a highly stable, uniform backspin that minimizes side-to-side drift and delivers tight, repeatable groupings over long distances.

Air-Tight Lip Geometry & Dual-Hardness Selection To prevent velocity drop-off, the front entrance lip is slightly narrowed and reinforced to form a complete, airtight seal around your AEG's air nozzle during the feeding sequence. This ensures maximum air compression from your cylinder grid passes directly behind the BB. To accommodate varying field limits and BB weights, the 2-pack provides two distinct hardness options:

• Black Bucking (60 Degree): Optimal for standard velocity limits (295–390 FPS). The soft rubber maintains highly flexible traction during cold weather conditions, preventing the hop-up from stiffening up.

• Purple Bucking (70 Degree): Engineered for high-velocity builds, designated marksman rifles (DMRs), or setups using heavy-weight ammo (360–460 FPS). This harder compound resists tearing and prevents over-hopping under intense pressure.

Key Technical Features:

• Stabilizing Dual-Point Mound: Centers the BB in the chamber to eliminate flyer shots and erratic side-spin.

• Optimized Sealing Entrance: Form-fitted lips seal tightly against the gearbox nozzle to retain maximum FPS.

• Versatile Two-Pack Bundle: Includes both a 60° (Black) and a 70° (Purple) bucking to match any field setup.

• Universal AEG Fitment: Fully compatible with standard TM-spec AEG hop-up chambers, including M4, AK, MP5, and G36 variants.

Field & Maintenance Recommendations The PTS MEC AEG buckings are highly drop-in friendly across standard rotary and traditional arm hop-up chambers. During installation, take care to slide the rubber onto the inner barrel ridge evenly without stretching the feed lips. Keep the internal contact patch completely clean and free of oil or grease. If cleaning the barrel with a patch rod, always back off the hop-up completely to avoid tearing the internal dual-point mounds.
