About the deal...

Available exclusively to JD Airsoft, S-T-T-S, in conjunction with M.D.D. Developments, the original MDD Hop system for all training weapon platforms.

The MDD Hop unit has been completely redesigned compared to the Hop chambers that are fitted in the current training weapon. The MDD Hop unit will be both easier to set AND will improve consistent accuracy, an outline of which is as follows.

The MDD Hop unit (Patent Pending) holds the hop adjuster steady in two places which not only improves consistency with regards to the BB trajectory but also improves the overall range.

This improvement is so good that we will GUARANTEE that when fitted to a Celcius 6.00mm Reformation II Barrel, the standard Celcius Training Weapon barrel, you will be able to hit a torso sized target (2ft. x 2ft) with a .25G BB at 60m before the BB’s start to spread*

The new MDD hop unit also allows for the Hop to be set through the ejection port cover using your finger instead of via the hex screw which you have to adjust via the magazine well which is standard on both the CTW and PTW Platforms. This new system is both more convenient and quicker to adjust as the Hop can be set without the need to keep removing the magazine.

Constructed entirely in the UK from CNC machine processes, the new Hop Kit will come complete with the following:

• New Aluminium Hop Chamber
• New Brass Hop Adjuster Ring
• New Hop Adjuster Pins
• New Barrel Key
• New Steel Hop Adjuster
• New Hop Roller Packing
• New Pin for Roller Packing
• New Chamber Packing
• New Chamber Packing Base
• Fitting Instructions

The MDD Hop Unit is an upgrade kit. It does not have complete parts and will require some of your existing parts to build.

Fits the following training weapon platforms:

Systema PTW
Celcius CTW
