"I purchased this rifle almost 2 years ago and I could tell you I was very pleased. It had an accurate range of 125 feet with .25 gram bbs. I have been playing for almost 4 years and this was my first high quality rifle. I would recommend this to beginners or maybe even some who has some idea what they are doing.


-May need to be upgraded for supreme performance

"The King Arms full metal Colt M4-A1 is great AEG. It features an aluminum receiver with nylon fiber hand guards, pistol grip, and stock on top of a functional bolt catch, all of which are extremely nice and well constructed. All in all, this rifle is steal for the price.


Amazing externals
Great internals
Realism of the bolt catch and Colt trades is a nice bonus


Orange tip isn't as graceful as Classic Armys

"My first impressions of this AEG are good. The full metal body adds durability without adding a ton of weight, RoF is good (bought an 8.4v intellect nunchuck), and power and accuracy are very acceptable. Borderline impressive with my king arms .25's.

-Full metal body for under $200 (Bought it at the $185 sales price + 18% off code, out the door for $170 shipped!)
-Good FPS (I chrono'd mine at 374-383 FPS w/ 0.20's out of the box)
-Trademarks are a nice touch, bolt catch sounds tinny and potentially fragile but functional.

-My hop-up has a tight spot in the adjustment wheel. It adjusts with little effort up to a certain point, gets super tight, and feels like it rolls over a bump and then adjustment can continue with little effort. The optimal hop-up point happens to fall in that hump, one side way too much hop-up, the other no where near enough. Very frustrating.
-Mags do not want to snap in place. None of my JG, DBoys, or even the King Arms high cap that came with it want to fit without coaching. Funny, the G&G 450rnd high cap I have fits like a dream...not sure what that's about.
-Handguards are tight, some batteries can be tight fit.

Overall, I'm happy with this purchase. At this price point, I can understand doing a little DIY to make it perform like I want it to. Performance is on-par with my buddy's KWA SR12 (cost him $400+), and I'm only invested at $170 for this AEG. Can't go wrong with this purchase, one of my favorite AEG's I own.
