Airsoft Electric Parts - Hop-Up and Parts

Master Mods are a new Internal Parts manufacturer bringing a whole new meaning to the term reliable. The Master Mods R-Hop Contact rubber is a hardened contact for use with heavier weight BB's, increasing accuracy & performance.

If you're building an AEG for maximum longevity and consistency, the Laylax Black Hop-up Rubber - Extra Soft will be an asset to your operaation. This HOP-up bucking is extra soft, making it ideal for full auto assault rifles, and is extra effective when paired with an OMEGA or OHM HOP-up nub. It offers an airtight design that promotes consistent FPS and HOP so your BBs will reach their destination successfully, time and time again.

Compatibility-wise, this is a standard AEG HOP-up rubber and should fit the vast majority of Airsoft AEGs on the market but may require expertise and tuning to fit. If you're getting out-ranged and out-performed on the battlefield, the Laylax Black Hop-up Rubber - Extra Soft belongs in your Airsoft replica.

If you are building out your M4/AR15 AEG for maximum performance the Gate EON HOP-up unit is probably already on your list! This precise HOP-up unit is constructed from CNC machined aluminium and is a rotary style unit which applies pressure directly to the top of the HOP-up rubber/nub to minimise side-to-side deviation.

This unit is compatible with M4/AR15 AEGs and can also be used with HPA setups thanks to the included nozzle sleeve which perfectly centres the nozzle for maximum efficiency.

If you're looking for all-round improvements in your HOP-up performance, the Maple Leaf Macaron HOP-up Bucking is calling your name! Designed to fit Airsoft AEGs and enhance both accuracy and range, the Macaron boasts a flat diamond-shaped patch for greater contact area with your BBs, giving a "Flat HOP" style effect when paired with an OMEGA or OHM HOP-up nub.

When compared to the Monster HOP-up bucking, the Macaron's contact patch is slightly less prominent, designed to provide a balance between range and grouping size as opposed to the Monster's focus on pure range. Compatibility-wise, the Macaron should fit most Airsoft AEGs though some level of expertise is required for fitting and tuning. If you want tighter groups and more range, the Maple Leaf Macaron HOP-up Bucking for AEG will do the trick!

If you seek more accuracy and range from your AEG, a HOP-up upgrade is the first place to start! The PTS Syndicate MEC HOP-Up Bucking for AEGs; Twin Pack includes a black HOP-up rubber and a purple one, equipped with a bridge-style contact patch to minimise side-to-side deviation and maximise accuracy. 

The black HOP-up rubber is designed for 295-360 FPS builds, being made from 60-degree hardness rubber and the purple 70-degree rubber is intended for high FPS DMR builds hitting out at 360-460 FPS on a 0.2g BB. If you're the techy type with a build on the go at all times, the PTS MEC HOP-Up Bucking for AEGs; Twin Pack is a great set to have in the toolbox!

If you're building your M4/AR-15 AEG to focus on range, accuracy and efficiency, the RetroArms CNC Rotary HOP-Up Chamber Gen.2 for M4/AR-15 AEG belongs in your build. This set is a full replacement rotary type HOP-Up unit for version 2 gearbox-equipped Airsoft M4/AR-15 platform AEGs and includes all of the parts you'll need to replace your stock HOP-up unit. The set also includes the choice of two HOP-up arms, one designed for flat HOP setups and one for conventional.

As with all internal upgrade parts, we only recommend this HOP-up unit for the technically proficient as it requires full assembly and does not include a HOP-up rubber or HOP-up nub. That said, the RetroArms CNC Rotary HOP-Up Chamber Gen.2 for M4/AR-15 AEG is widely regarded as one of the best options out there for the pros, and when set up properly, it has the potential to outrange anything else on site!

If you need more range and accuracy from your Airsoft AEG, the 4UANTUM Friction Pro High-Performance AEG HOP-up Bucking belongs inside! This cutting-edge HOP-up upgrade set includes an HOP-up rubber/bucking with a uniquely shaped contact patch and an OMEGA-style flat nub, ready to be installed into any AEG-type HOP-up unit.

The Friction Pro bucking was developed over 2 years of rigorous testing and, since its launch, has taken the Airsoft world by storm. We've been extremely impressed by the performance of this bucking during testing, offering exceptional range and a remarkably tight grouping, a combination other buckings often compromise on.

With the ability to lift up to 0.48g BBs in its stride with 60-meter accuracy when set up correctly, the Friction Pro High-Performance AEG HOP-up Bucking from 4UANTUM is ideal for any long-range AEG setup but is especially potent in a DMR build!

If you use heavy BBs and really want to send 'em, the Maple Leaf MR HOP Bucking for AEG belongs in your build! The MR HOP-up Bucking offers a wider and longer “R-HOP” style contact patch for increased HOP-up effect and extended range with heavy BBs. The MR HOP also uses a shield-shaped groove around the contact patch to allow it to stretch and add to the strong HOP-up effect along with an air seal improving C-ring which ensures the bucking is firmly fitted to the barrel and unable to slip or rotate.

MR stands for “Maximum Range”, a design based on home-brewed R-HOP buckings, intended to prioritise range over grouping size and is best used paired with a Maple Leaf OMEGA or OHM HOP-up nub. Compatibility-wise, the MR HOP is designed to fit most Airsoft AEGs but as always, a certain level of expertise and tuning will be required for installation. If you're committed to long-range leaning and want your primary performing at its best, the Maple Leaf MR HOP Bucking for AEG is essential!

If you're building an AEG for maximum range, the Maple Leaf Monster HOP-up Bucking for AEG will be an asset to your objective. Designed with a diamond-shaped contact patch to increase surface contact with your BBs, the Monster is ideally used with heavy BBs (0.28g+) and provides increased HOP-up effect, especially when paired with an OMEGA or OHM HOP-up nub.

The Monster is available in a wide range of hardnesses, offering an option for any build objective, from CQB to DMR. Compatibility-wise, this is a standard AEG HOP-up rubber and should fit the vast majority of Airsoft AEGs on the market but may require expertise and tuning to fit. If you're getting out-ranged and want to go from prey to predator, the Maple Leaf Monster HOP-up bucking belongs in your build!

Are you having HOP-up troubles with your M4 platforms? Delta Armory has you covered! This HOP-up chamber is a replacement part and comes with all the necessary pieces for installation, including the HOP-up rubber and nub. The main chamber is made from a sturdy plastic polymer and is compatible with all M4 style AEGs which have V2 Gearboxes. It is an affordable solution to mend your platforms with damaged or old HOP-up chambers.

The Delta Armory HOP-up chamber is an affordable replacement for M4/AR-15 AEGs, fix up those old primaries and get them shooting again with this low-price solution.

If you're the techy type and want to maximise your AEG's efficiency, the Bolster Armouries HOP-up to Barrel O-Ring Shim Set belongs in your toolbox! This set includes 10 o-rings designed to fit around the HOP-up unit and inner barrel, forcing it back to meet the gearbox as seamlessly as possible to promote maximum efficiency and reduce shot-to-shot FPS deviation. 

This set is designed to replace the "one size fits all" HOP-up unit spring, providing a user-customisable solution to account for manufacturing tolerances. While this will take a bit of trial and error to get the perfect fit for your AEG it should prevent airseal qualities from reducing over time and avoid that annoying realisation that you forgot to reinstall the HOP-up spring after upgrading or maintenance! 

The Bolster Armouries HOP-up to Barrel O-Ring Shim set should fit almost every AEG on the market and you probably won't need to use the full set, meaning you might even be able to replace two HOP-up springs with a single set. 

If you seek more accuracy and range from your AEG, the Prometheus Bridge HOP-up Tensioner for AEGs will help you achieve it! Supplied as a pack of two tensioners, these are the "Bridge" style design with a central groove designed to reduce side-to-side deviation, focussing on maximum accuracy and providing the smallest grouping possible. The contact surface provided by this HOP-up nub (another word for tensioner) is far larger than the standard, resulting in a stronger backspin effect and extended range with heavy-weight BBs. 

The two tensioners included in the set are of different colours; one purple and one black. The purple tensioner is made from softer rubber, designed for sub-350 FPS builds and the black one is slightly harder, ideal for 350 FPS and above, making it the perfect tensioner for an AEG DMR. Compatibility-wise, these tensioners should fit almost any Airsoft AEG HOP-up unit but as always is the case with internal upgrades, we only recommend these for experienced techs and those who know their way around AEG internals. If accuracy and range is your objective, the Prometheus Bridge HOP-up Tensioner for AEGs belongs in your build!

Designed specifically for the Gate EON CNC Rotary HOP-up chamber, the Airtech Studios Full Upgrade Set for Gate EON HOP-up Chamber includes a TDC trolley, 2 x M-nubs and an inner barrel centring unit. This set is designed to convert the Gate EON into a true TDC unit, giving you more range and accuracy than ever before!

The benefits of a TDC HOP-up unit include a stronger HOP-up effect and less chance of side-to-side shot deviation when using heavy BBs at high FPS. This part will require a certain amount of expertise to install but thankfully, the process is fully explained on the Airtech Studios website. If you want to get the most out of your Gate EON HOP-up chamber, this kit will do the trick!

If you're working on the ultimate AK AEG build, the RetroArms Precision CNC HOP-Up Chamber for AK AEGs is an integral part! This CNC machined HOP-up unit is made from 7075 Aluminium, granting it steel-like strength and flawlessly precise machining with the weight reduction perks of aluminium. 

The most unique aspect of this HOP-up unit is the inclusion of what RetroArms call the "collet nut", a threaded nut which seals the gap between the inner barrel and HOP-up chamber walls. This saves you any messing around with PTFE tape and ensures your platform's air-seal is perfect, resulting in more consistent FPS readings translating to improved accuracy downrange. 

The set includes everything you'll need to complete the HOP-up unit with the exception of the bucking, nub and inner barrel but will require assembly. As such, we only recommend this HOP-up unit to those confident working on Airsoft internals. Best used with the RetroArms CNC Version 3 Gearbox but compatible with almost every TM-based AK AEG on the market, the RetroArms Precision CNC HOP-Up Chamber for AK AEGs is a fantastic upgrade option for performance-oriented AK build!

Turn your stock ASG Scorpion EVO's HOP-up chamber to a TDC design without having to replace the whole unit. This kit includes everything you need to install the system into your current HOP-up chamber. It is compatible ONLY with ASG Scorpion EVOs and will not fit in any other HOP-up systems.

TDC (Top-Down-Centre) HOP units are incredibly sought after due to the increased friction they add to BBs, which increases the effectiveness of the HOP applied to your BBs. By installing TDC to the stock HOP-up you are guaranteed compatibility with the platform.

The set also includes rubber nubs, these ensure the HOP is stable while BBs accelerate through the unit, further improving the performance and consistency of your ASG Scorpion EVO. This is a very complex installation process and we only recommend it if you are confident in your understanding and ability to fit it to your HOP-up chamber.

If you are looking to upgrade your HOP unit, in most cases these days there isn't much to gain if you already have a rotary unit in your gun. This is the exception! Krytac has taken the rotary HOP unit and added in audible and tactile clicks when you adjust, locking the unit in its set position and allowing you to adjust accurately even in low light conditions! The unit also has engraved numerical setting indicators around the adjuster, allowing you to keep track of which setting works best with which BB weight, avoiding the trail and error! This package also includes a KRYTAC HOP rubber.

If you are building an Airsoft DMR this enhanced HOP-up rubber set from Laylax Prometheus should be on your shopping list! Laylax Prometheus has a fantastic reputation for enhanced HOP-up buckings, providing the Purple bucking used in the Bolster Armouries ONYX AEG series thanks to Prommy's wealth of experience and pedigree. We love them, and we think you will too!

This bucking is designed for builds shooting at 350-400 FPS, putting it right in the sweet spot for DMRs. When installed, this set should improve range, enhance air seal and allow for heavier weights of ammo to be used. Compatibility-wise, this should fit the vast majority of Airsoft AEGs which use the standard TM AEG style HOP-up bucking/rubber and nub, which is almost all of them!
