"I'm an airsoft noob but was ready to join my son in playing the game. I purchased this Matrix M4 at the Evike pro shop in Spring, TX. I knew I wanted something better than "toy grade" but didn't want to go crazy. The staff at the store had nothing but great things to say about this gun. The stock spring did run hot at the indoor range so add $10 if you need to bring it down to 350 fps or below and another $50 to get you going with a battery and charger.
I purchased the FDE model and it looks legit. I did pay more at the store, BUT that's because they'd already done some custom work on it; metal barrel, integrated "suppressor", metal quad rail and collar.

Solid Construction
GREAT value for the $$
Accurate out of the box
Looks super cool
Metal magazine (runs like a champ!)
Metal gearbox and G2 micro switch

No sling points
For indoor play - ran nearly 400 fps out of box. So, had to spend another $10 for spring (but it was an easy swap!)
No battery/charger - add another $50 to price

"Expect great things i got this gun thinking it would be a nice little gun that if i broke it i would not really care boy was i wrong this gun had so many things that impressed me beyond belief one of my team members spent nearly $300 on a rife but this one only spending $110 (after the battery) kept up perfectly with his $300 dollar one occasionally out preforming his anything bad about this was easily fixed overall WAY IMPRESSED

light weight
fast rate of fire

no battery included
no rails except for the one under the carrying handle

I recently purchased the Matrix M4 Sportsline AEG for $99.00 on sale. The model I got was the M4 COMMANDO version, which is the smallest model, (great as a backup to my Sniper rifle). When I got the package, it was in a nice Matrix box. Inside the gun was nicely secured. After checking for damage, I grabbed a charged 9.6v battery, 25g bb's, and fired it.
Sturdy body
Nice RESPONSIVE micro-switch gearbox
Great ROF (for $99)
300 rd metal magazine
Good FPS
Pretty dang ACCURATE

Cons: Have NOT found any.
