  • Silicone construction
  • 50° or 80° Hardness
  • Improves range & accuracy

If you want tighter groupings and more range, you're not alone! Thankfully, Maple Leaf is here to make your AEG shoot like a laser beam with the OHM Silicone AEG HOP-Up Tensioner; Solid Edition. This HOP-up nub/tensioner is ideally paired with a Maple Leaf HOP-up bucking and like much-lauded "Flat HOP" nubs, is designed to provide a stronger HOP-up effect for heavy-weight BBs and to reduce side-to-side shot deviation, improving accuracy and range as long as you do your part.

The OHM Solid Edition is available in two different hardness degrees, 50° for standard FPS and BB weights and 80° for heavy BBs (0.32g+) and DMR FPS levels. The Solid Edition differs from the Hollow Edition in its solid form which prevents the tensioner from deforming when used with heavy BBs travelling at high velocity. The inner surface of the OHM is also concave, making it the perfect pairing for Maple Leaf buckings with concave contact patches.

Whether you're working on a DMR build or accurising your primary AEG, the Maple Leaf OHM Silicone AEG HOP-Up Tensioner; Solid Edition will give you the performance you need!

  • Steel construction
  • 18:1 ratio gearset
  • Compatible with version 2 and 3 gearboxes

For those working on a build which pushes the limits, you will require some decent gears! Introducing the VFC Avalon 18:1 Steel gearset, a standard ratio gearset constructed from hardened steel. The set includes a spur gear, sector gear, and bevel gear which are all precisely machined for perfect meshing and smooth, reliable performance.

These gears are tuned to an 18:1 ratio, which means for every 18 revolutions of your motor the gearbox will complete one full cycle. The benefit of using standard ratio gears is that you can make either a DMR or a high-rate-of-fire CQB beast without wholly committing to one or another, meaning you can adapt your build to the scenario which suits, and without overstressing the gearbox by running it considerably beyond its design parameters.

Treat your AEG to some premium gears and have it shooting consistently for a long long time, plus you have the flexibility of running a DMR one day, then alternating to a rapid-fire monster the next day!

The Airtech Studios Set of 4 Spring Shims;11mm Inner Diameter are designed for most VFC, Krytac & ASG spec spring guides. These reinforced polymer shims slide onto the spring guide and add additional tension to the existing spring within the gearbox. The different sizes of shim add different amounts of FPS to your replica. The smallest shim adds roughly 5 FPS to your replica and the largest adds roughly 20 FPS. The shims are designed to be of various sizes so that you can combine them and find the optimal FPS increase to keep your replica within site limits.

These shims give you an easy way to increase your platform's FPS without having to have multiple springs. Simply add or remove the shims as and when you need to adjust your AEGs FPS, with minimal hassle!

  • Reinforced polymer
  • Increase RPS and improve FPS consistency
  • Pull Stronger springs without piston/rack damage

Take your AEG to the next level with a revolutionary Piston. It has been redesigned to ensure a premium performance. The Nightstalker piston has eradicated all the common weaknesses of an AEG piston to create an almost flawless design. Firstly, it has been constructed from a reinforced polymer, one that can pull stronger springs without causing damage to itself. It also has a drop-in angle of engagement (AOE) which helps distribute the force evenly on the teeth of the piston rack, reducing the risk of premature wear or breakage.

The stress points of the piston have been revised to spread the wear between 3 contact points and drastically reduce the load on each tooth. Another upgrade is that the piston rails have been revised to reduce friction, this removes the wobbling of the piston against the gearbox and keeps it completely straight. All these revisions and enhancements make for a consistent improvement in FPS and performance. Make your AEG premium, for real.

    • Less wear than O-rings
    • Lower contact pressure
    • More consistent pressure

    For a sturdy upgrade to your AEG the FPS X-Ring is a piston head seal with a quadrilobate section, which during dynamic stresses are not subject to seal rounding.

    X-Rings have less wear than O-Rings as they require less radial pre-stress which results in lower contact pressure.
    A lubricant reservoir can be created between the sealing lips using silicone.

    Installing this ring will optimise the sealing effect thanks to a better pressure distribution due to the square section.
    The X-Ring eliminates any negative effects due to the closing line of the mould, as this is located in the groove between the two lips.
