"This is a great gun! I bought it a year ago, and it still works as good as it did without any upgrades. However, I only played a handful of times.
The full metal is and feels great. It feels so solid and realistic. The stock is solid. I would prefer M-LOK over keymod, but keymod definitely good, especially since you rarely find M4s with M-LOK under $200. Its grouping at 20 yards with 0.20g BBs is ABOUT 5 to 6 inches, and its grouping is at 20 yards with 0.30g BBs is around 1 to 2 inches, which is awesome! Personally, I don’t like how big the mag release is. I’ve dropped my mags multiple times by accidentally bumping the mag release. However, the ambidextrous mag release is awesome. The hi-cap mag it comes with works just great, no problems yet. The 3 detachable rails it comes with is a good amount, and you probably won’t need anymore, unless you want an M203. If you rack the gun, the bolt catch stops the panel (bolt carrier on a real gun) from covering the hop-up adjuster until you release the bolt catch. If you take the handguard off, I suggest that you replace the set screws with longer ones. I got some from Ace Hardware. The pistol grip is at a weird angle, but I prefer more of a MOE-K2 steepness. I'm not sure what the common thoughts are about CYMA, but this gun beats my Lancer Tactical all day!
