[R04C00][035749 / CA056M]

For a decade, Classic Army has been setting standards for the airsoft industry. Long known as a trailblazer in innovative airsoft gun design, this Hong Kong-based company has teamed up with Tango Down to produce the Classic Army M4 ECR4 Carbine Blowback AEG Airsoft Gun from Airsoft GI. This gun is a worthy addition to the company's lineup and continues Classic Army's history of innovation and excellence.

Tango Down has been a well-known manufacturer of real steel weapon furniture for years and an OEM provider for numerous other real steel companies. Their products have earned a reputation for comfort, ease of use and solid construction. The metal material used for the gun adds sturdiness as well as a realistic look.

The Classic Army Full Metal Tango Down ECR-4 Blowback Airsoft Gun brings that innovation and quality to the airsoft market. The ECR-4 boasts numerous features that make it just like its real steel counterpart. If it were any more realistic looking, you'd probably have to hand out bulletproof vests. From the officially licensed and trademarked metal body to the CNC-machined rail system, the enhanced carbine MOD stock, the Tango Down quick-detach battle grip-style vertical grip and the crisp-feeling blowback system, the ECR-4 is sure to impress on or off the field.

Product Information:
Got this gun for my son for Christmas. Trigger broke off with in the first 5 minutes of battle. Airsoft GI referred me to Spartan Imports who seems are going to be a big help. Airsoft GI does not deal with warranty issues.

Didn't use it long enough to find any.

Broke in first 5 minutes of use..

This gun is a better field gun than CQB gun, but the ROF is terrible. You can't shoot enough bbs to hit someone, so i would recommend getting a non blow back gun because I feel like it would be faster.

nice and sturdy, strong metal, mostly metal externals really good and nice.

internals are ok, but can be much better.

Product Information:
Got this last year , very solid (kind of ) have had a couple issues with this out of the box though . Charging handle is very wobbly and it's built that way . But plate on the crane stock is a pain . I broke off a piece of it trying to open it . Wires are waaay too long for the battery . Rail has a slight wobble to it as well . But I must say this gun shoots very fast . No feeding issues , runs great on 9.6 v mimh battery and shoots like a mini gun with an 11.1 v Lipo as expected lol

Full metal construction
Good internals
Comes with a mosfet out of the box
Seems durable

Wobbly upper reciever (rail )
Wobbly charging handle
Battery wires are way too long
Butt plate has bad design (way too hard to open)
