||I have owned about 4 of these.
This is a very decent gun for the price.
You get a tight bore barrel and 380 fps out of the box
This is a great beginners gun and this is the gun I learned how to open the gearbox and work on and upgrade.
Shoots at about 380 fps with 0.20 gram bbs out of the box.
Really good air seal
Tight bore barrel 6.04
High Quality plastic body.
nice weight (not too heavy or too light)
Charging handle opens the dust cover
Outer barrel is 2 piece so you can fit a shorter barrel to make cqb gun
Trigger response is slow on semi auto
Some, not all, of mine have had trigger issues if your like me and have a heavy trigger finger
If you want to put a magpul handguard you will need to make adjustments to the front sight
The all metal version of the Matrix is a better gun because it has silver low resistance wires and gives a quicker response time. Also has upgraded bearings and spring guide.
This gun is great but you will probably eventually have to replace the trigger assembly and add silver wires to it.
If your like most of us in this hobby called AIRSOFT and love to open your gearbox and upgrade and see the enhanced performance benefits of your work then this gun is a great one to get. Low initial costs and upgrading a few items will not cost that much more and you learn how your gun works.
If you do not want to touch your gun ever then spend more on a higher end gun which will last longer but all guns will eventually require service.
I rate the Matrix M4 Sportsline 8/10
