This M4 Carbine is fully licensed by CAA Airsoft, which is well-known as CAA for its real steel weapon conversions and parts, including the RONI pistol to carbine conversion package that has been turning heads recently. CAA Airsoft’s M4 Carbine AEG features full metal construction, realistic weight, and the aggressive style that CAA is known for. Unlike most M4 AEGs which feature a metal upper-receiver but nylon lower half, this one is all metal. From a design perspective, the CAA Airsoft M4 is nearly identical to its live-fire counterpart. From the three rail hand guard to the cheek riser-equipped stock, it is easy to see that this is a CAA design. The M4 magwell features some cool CAA Airsoft branding and the gun comes with a small assortment of additional rails which can be fitted to the handguard. Also in the package is a 360 round, high-capacity magazine in the style of live-fire CAA mags. The magazine is well-constructed and features a unique, accident-proof BB well lid which flips open instead of sliding like most hi-cap magazines do.

Conclusion

After having used this AEG for a while now, I feel very comfortable giving it a four out of five stars. The CAA M4 Carbine is durable, reliable, and built to last with CAA’s style and rail system. I would have, without question, given the gun a five out of five stars if the issues of the stiff magazines and accessing the battery were not present.

[wpcol_1half id=”” class=”” style=””]Pros

• Incredible build quality and style
  • Love the full metal receiver
  • Love the M4S1 Picatinny Rail System for its Functionality
  • Love the well-designed CAA magazine
• No wobble in either the handguard or stock
• Shot at a relatively-constant 387fps using 6mm, .20g BBs
• The built-in battery case is a great way to store your extras in the field
• Good rate of fire and very accurate

[/wpcol_1half] [wpcol_1half_end id=”” class=”” style=””]Cons

• Magazines are very stiff to insert and remove from the gun
  • A quick fix is simple to file down your magazines with some sand paper. If you don’t want to go that route, know that, after a while, most magazines will get easier to use, but it takes some breaking them in
• Removing the battery is a a chore if you have the removable bottom rail attached to the handguard. You need to remove any attachments on the rail and the rail itself to get into it and reach the battery

**UPDATE: I have discovered that non-metal, standard-style M4 magazines (not fancier styles like P-mags and the like) insert and remove from this weapon far more easily than standard metal magazines.
