The APS Kompetitor series of AEG's are meant to bring high quality internals and intermediate level performance to a more affordable platform.Out of the box, the Kompetitor series of M4 Carbines feature the APS V2 Metal HYBRID gearboxes with an electric blowback feature for added realism. The HYBRID gearbox is the same one that can be found on APS's higher end models of AEG's so it shares the same features such as a QD spring change system to allow for quick spring swaps without disassembling the gearbox. Quality has not been compromised in favor of value; these rifles are built with high quality reinforced polymer receivers, grip, stock, and handguards. Metal parts include the barrel, delta ring, charging handle, and buffer tube.An excellent choice for anyone looking to get started in airsoft but want higher quality internals as well as performance that can stand up to other intermediate level AEG's.

"This is a really good cheap EBB for added realism.

Pros: Its light
Easily customized
Simple tear down
Good accuracy
Full Metal Gears
*Fast Spring Removal*

Cons: Polymer body
No Metal Flash hider
Front wiring bit short, and tight

This is a good AEG for the price, I own 3 APS guns and they are all good and have been for about a year.

"I bought this on a deal breaker i.e. I paid less that what its going for currently $120. And I wanted a M4 platform with some recoil.

To be honest this gun performs pretty good to be of the lower end the EBB in my opinion is the major key for it selling.
It has good accuracy, doesnt missfeed much and I mean like 2 bbs out of 100.

Pros: Looks good.
Feels good man!
Light weight, easy maneuvering.
Easily change hand guards. (I upgraded mine)

Cons: Front wiring of the stock is bad when its stock.
The crane stock is of extreme cheap design.
Not sure if the stock is removable.
Has some plastic internals.

All in all this is a good starter to medium user friendly M4.

"Ok so i bought this gun 5 days ago and shipping was fast. Got here on a saturday and only took 3 days. Right out of the box the gun was a bit dirty but its easy to clean. Comes with a polymer 300rd high cap and an unjaming rod. First time i shot this gun it shot perfect. The accuracy was very good and the hop-up was already perfectly adjusted. The front iron sight is very accurate but the one in the back really isn't so i recommend either just using the one on the front or just getting a sight. Now remember that it doesn't come with a battery but to put it in you take off the bottom half of the compartment. I accidentally opened up the top and it was VERY hard to put back on. It comes with rail covers and it comes with a fuse so i think it might be Lipo ready....don't take my word for it though. I have been hearing that the electric blowback can damage the gun but honestly it has been working perfectly for me. The front reciever is kinda hard to take off the first time but after you do that it starts getting easier. Well hope this helped
