From RedWolf Airsoft:

That’s right guys and girls, With the recent announcement from Systema regarding their ‘Energy’ line of products, we’ve managed to pick up the complete line of Energy products to go on our shelves.
Is this another upgrade from the Systema revolution gearbox they launched some time back?

Ranging from gearboxes, pistons, cylinders, gears to motors plus many more other smaller parts.  You can dramatically transform your AEG into something new, something different and definitely more efficient.  If you’ve read the previous news post regarding Systema’s line of products please feel free to check it out again here.  That page includes static data for the motor performance under a few variables that definitely make this an interesting read.

By reducing the initial inertia required to start the mechanical system, not only will it reduce the energy required to run the system but also reduce the mechanical wear on the components due to the reduction of the forces involved.  Systema have also looked into various other ways into making their systems more reliable in different conditions as well as being more efficient, talk about attention to detail here… These guys really have been digging deep and thinking outside of the box, we’ll go into detail on the product report here individually, click the following link for more details.

Whilst we’re on the topic of AEG parts, allow us to introduce the Madbull’s ultimate 3-in-1 Hopup Chamber for the M4/M16 series.

Another practical innovation from MADBULL, this new metal hop-up unit / chamber has 3 functions in 1! Designed by airsoft player Brian Holt, Madbull implemented Brian’s idea with the following smart features:
1. LED Tracer Unit (Optional and available separately from Madbull)
2. Chamber Lock (Prevents BBs from falling out when you eject magazine)
3. Easy adjustment using new design dial for more stable hop-up
This set also includes a free MADBULL blue 60 degree SHARK hop-up bucking rubber.
Note that the chamber lock function works via an O-ring in the BB feed tube that goes up to the firing chamber. The O-ring prevents BB’s from falling out of the gun when you pull the magazine out, which is normal in a Marui type gearbox. If you find this causes any problems for you, or you prefer that the 3-4 BB’s in the feed tube fall out of the gun during reloads, you can simply remove this O-ring to disable the chamber lock function.

New hop-up adjustment dial stays in place and won’t shift from vibration during full-auto firing, giving you more reliable and consistent hop-up than in traditional guns with slide-type hop-up adjustment lever.

And if you need one more reason to get this hop-up unit, Madbull tested this hop-up unit on the Echo1 M4 and got a 5% increase in power due to a better air-seal. So you get 4 benefits in one unit! Need we say more?

Below is the test result using an ECHO M4 (fps):

	Average	High	Low
stock echo barrel, stock blue bucking (MadBull Blue Bucking) and stock hopup	297.34	303.5	289.5
stock echo barrel, NEW MadBull, bucking(in package) and NEW MadBull HopUp	312.55	317.3	308.4
