The Matrix "Challenge Kit" is a Limited Time AWESOME deal that we are offering to YOU!
A Matrix Sportsline M4 with a free metal body ($80 value) for those that are Airsoft savy, installing a metal body (without even having to go into the gearbox) is a piece of cake!
You can refer to Evike.com TV, our youtube channel for installation guide. We do warranty and guarantee that all the parts on the gun is brand new, in perfect condition. (Warranty covers all parts with the exception of the plastic body which will be useless trash after you install the metal body.)
The Matrix M4 series is rated to have the best 8mm gearobx in the market with superb reliability and performance. The sportsline, like all others, does have a ABS body for starters, which could break after use. But it is nevertheless super popular because a metal body will cost $100 more.
Matrix Sportsline? What's the difference between this Sportsline M4 model and the very popular full metal version? Just like all sports line AEG, it doesn't have metal body, it has a polycarb cylinder head instead of a steel, no ball bearing spring guide. The $100 price differences could easily get you those upgrades and leave you with a spare if you want your AEG heavier!

Review:
Initial Look & Feel:
Solid, durable and realistic. Everything you'd expect for great value. Matte black finish. 1:1 scale to a real steel M4 Carbine. Nice logo. Expect more and spoil yourself today.
Performance:
Air Seal: The Matrix M4 shoots an average of 30~50 FPS higher than most other brands with the same spring installed. Which means it has superb air seal and energy efficient. Less work on the Motor and Gear only means a more durable AEG.
Accuracy: With 6.04mm tight bore barrel already installed, it is also much more accurate than any other M4 AEG under $120.
Reliability: This AEG is completed with all Matrix parts, resulting the best factory direct value per dollar in the market. The very popular complete gearbox from Matrix is retailed for $110, and it is rated one of the best gearbox by skilled technicians. The firing is smooth and the rate of fire is great with good accuracy and range.
Stress Test:
Upon receiving the first batch, our technician fired 10,000 rounds (35 m4 hicap / 11.1V 1350mah Lipoly battery) on randomly selected five Matrix Tactical Systems M4 and the result was amazing. Each gun test was completed within 1 hour to really "stress test" these AEG. After the first 5000 round within the hour, the motor starts to get warm, and gets pretty hot by the 35th hi-cap. One anti-reversal latch broke during the stress test. To those that the above statements makes any sense to, this AEG is more durable and stable than most we have seen. It is more "Lipoly Ready" than any AEG out there, however, we still recommend only experienced gamers to use li-poly, as the gaming advantage comes with responsibilities.
You think you can take the challenge? We even made the video for you. Be one stop more into Airsoft today!
