Details on the PRO version:
In the PRO version, all components of the trigger group are made of steel and the sear is made of hardened steel.
Compared to the standard version, the Nozzle has been reinforced and is now made of robust nylon fiber. This also withstands the high pressure of CO2 much better.
To ensure a perfect seal, the PRO version has a CNC-machined Pistonheads with ventilation. This also ensures a smooth-running system in the cool-down area.
Due to the better seal, the energy can be slightly higher than with the standard version.

Our Begadi Efficiency valve made of stainless steel is already installed in this gun.
Thanks to its smooth operation and revised design, this valve ensures a significantly more constant energy output and reduces gas consumption by up to 15%.
For example, it is possible to fire up to 55 rounds at 0.85 joules from a small 1911 GBB magazine (data with ProTech gas at 18°C). This valve also has an additional O-ring on the inside so that the firing piston is sealed to the rear when opened and no gas can escape.
The amount of gas that can escape per shot has been set so that the GBB can work without any problems but does not go into cool-down so quickly. As O-rings can always leak, we use a special material here that is resistant to cold. This does not contract in the cold and lasts much longer. All components of our valves are CNC-machined from stainless steel. Due to the high pressure of CO2, we work with a PTFE/Teflon seal which is also CNC machined
The Begadi Efficiency valves are not available individually, but only when installed in magazines or GBBs as/where we offer them in the store. Customers who have purchased magazines or GBBs without Begadi Stainless Efficiency Valves from Begadi in the past can have the Begadi Stainless Efficiency Valves retrofitted by our workshop on request. This service is limited to magazines & GBBs purchased from Begadi

Maintenance Kit:
To ensure that you as a customer have many years of fun with the purchased weapon, we include some wear parts in the delivery, which can be replaced if necessary in the event of maintenance or damage, the contents of the kit are as follows:
- Inlet valve
- Original KJW exhaust valve incl. O-rings
- Magazine lips
- Magazine follower
- O-ring for magazine base
Note on the additionally supplied original KJW exhaust valve:
KJW only supplies its GBBs and magazines including their original exhaust valves. Therefore, for the Begadi versions of the magazines, the original KJW valves are subsequently removed by the Begadi workshop and replaced with the Begadi Stainless Efficiency valves. The original KJW exhaust valve is then removed and supplied. We recommend keeping the original KJW valve as a backup. The outer O-rings can also be used for the Begadi Stainless Efficiency valve.
In the course of the valve replacement by the Begadi workshop, the magazines are also tested, including firing tests in the corresponding GBB. These tests occasionally result in minimal traces of use on the magazines. Unfortunately, this cannot be completely avoided during tests.
