If you have damaged your HOP-up unit and are looking for a replacement, CYMA are now offering their original HOP-up units as an aftermarket part. This unit is for the CM.041K and CM.041PDW AEGs, but will not fit the full sized CM.041 AEGs. The unit is constructed from polymer and comes complete other than the HOP-up rubber. The HOP unit, slider, c-clip and HOP nub are all included, so if you have lost or damaged one of these bits you are in luck!

If you're building out your Shadow 2 GBB and seeking more accuracy, the Maple Leaf Complete HOP-Up Chamber for KJW/ASG Shadow 2 GBB is an easy way to get there! This complete HOP-up chamber group is practically a drop-in fit and pre-built so you don't have to do any of the fiddly stuff!

The set includes a Maple Leaf 6.02mm Tightbore inner barrel made from stainless steel, the Maple Leaf HOP-up chamber and a Maple Leaf Autobot 60° HOP-up bucking paired with the much-lauded Maple Leaf I-Key. Compatibility-wise, the Complete HOP-Up Chamber should work flawlessly with both ASG and KJ Works CZ Shadow 2 GBB pistols.

If you want to push your VSR-10-based sniper rifle to the absolute pinnacle of accuracy, a TDC mod should do the trick! The Hades Airsoft TDC HOP-up Unit Set for VSR-10 Sniper Rifle is designed to replace the original HOP-up arm and adjuster, providing direct pressure to the top of the HOP-up nub and bucking to eliminate side-to-side shot deviation.

Installing this TDC unit will require some extensive, irreversible modifications to your base sniper rifle, so we only recommend this set for those who are confident with power tools and have a decent level of Airsoft technical knowledge.

The unit requires you to drill a hole through the top of your outer barrel using either a 5mm or 5.5mm drill bit and the included drill guide, inserting the guide into the stripped outer barrel to ensure the hole is drilled in the right place. Hades also recommends that when the modification is complete, that you glue the TDC unit to your outer barrel using super glue or another strong adhesive.

If you are the type of sniper that likes to get their hands dirty with modifications and you want your VSR to outrange and outshoot the rest, this kit will do it!

If you're working on a beast of a sniper rifle, the Trusight TDC Conversion Kit for VSR-10 will get you there! This TDC HOP-up conversion set is a very impressive design, providing TDC functionality for reduced side-to-side deviation and a stronger HOP-up effect without requiring your outer barrel to be drilled!

That said, limited modifications to the TDC carrier are required due to purposely being made off-spec. This allows you to get the perfect fit for your specific HOP-up chamber by carefully filing it down with hand files. Installation instructions are available on the Trusight Website but for those who don't like reading, check out the video here.

The main benefits of this set over other TDC kits are it doesn't require any permanent modifications to your original VSR-10 parts and you won't need to carry an Allen key in-game or ruin the looks of your VSR with a dial on the top of the barrel as you'll be using the original slider adjuster. Compatibility-wise, this set is designed specifically for the Tokyo Marui VSR-10 series but may also fit VSR-10 clones, though extra modification may be needed for a perfect fit.

The Airtech Studios RetroArms Rotary Centring Unit is an easy upgrade to improve your AEG's accuracy. It is constructed from high-density polymer and fits a RetroArms CNC Rotary HOP-Up Chamber Gen.2 ONLY. It prevents the hop-up unit from wobbling side to side. Once fitted, the RetroArms Rotary HOP-Up Chamber will be securely fitted in place and sit in its true centre position, which prevents BBs from swerving at a tangent when shot.

As well as removing the wobbling from your HOP-up chamber, it also provides a better air seal due to the improved tightness of the system, resulting in a more stable FPS output from your AEG. While the power upgrades for shooting BBs further are significant, they wouldn't be effective without accuracy. It's often that small parts like this are overlooked in Airsoft upgrades but they have a major impact and the Airtech Studios RetroArms Rotary Centring Unit is exactly that.

Improve the consistency and accuracy of your RetroArms CNC Rotary HOP-Up Chamber Gen.2 with a simple polymer part, the improvement will be instantly noticeable!

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.

The Maple Leaf Delayer OMEGA Nub is a HOP UP Rubber Nub For Airsoft Hop Up Units, it matches the shape of the BB to increase accuracy and overall performance of your airsoft gun.

If you're looking for accuracy improvements for your M4/AR-15 AEG, the Delta Armory TRINITY R-Hop Bucking Bundle for AEG is what you need to tighten your groupings. This set includes an enhanced HOP-up arm, HOP-up bucking and OMEGA-style nub manufactured for Delta by upgrade legends Psionic Upgrades. The included HOP-up arm is designed for M4/AR-15 AEG rotary HOP-up units, specifically the Delta Armory/Specna Arms/Evolution/Lancer Tactical type but the bucking and nub are compatible with other Airsoft AEGs of all different shapes and sizes. 

The inner patch of the TRINITY bucking is diamond-shaped, similar to the Maple Leaf Super bucking, intended to improve accuracy by applying backspin more consistently. The advantage of using a TRINITY set rather than doing all the mods yourself is its simple drop-in installation, low price compared to sourcing a separate bucking, nub and HOP-up arm and guaranteed compatibility, meaning no chance your nub doesn't work with your chosen bucking. If you're looking for tighter groupings from your Airsoft AEG, the TRINITY R-HOP Bucking Bundle is the one to go for!

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!
