Tokyo Marui Colt Licensed M4 CQB-R MWS ZET System Gas Blowback Rifle w/ Cerakote Firearm Finish

"Perfect right out of the box. No need for upgrades. 380 fps on green gas/.20's on a hot day. Performs well and feels great.

"Extremely satisfied with what I got. The gun performs really well: Bolt lock back even with cold mags and constant full auto (~200 rounds with 2 magazines). The range leaves a bit to be desired, but since I use R134a gas instead of green gas/propane, I can't ask for much. The accuracy is really nice if you adjust your hop-up properly.

The gun doesn't kick as hard as others GBBR like the GHK, WE or KJW, but that's to be expected with their design. If you are one to look for consistently good performance with no failures but don't mind sacrifice a bit of realism, then this is the gun for you. It-just-works!

Side note: If you want to change the handguard, remember that the barrel nut is proprietary. Make sure to buy one of a Spear Arms, PTS or Asura Dynamic Barrel nut adapter/spacer so that you will be able to mount AEG spec barrel nuts. If you want to mount real-steel DD, Geissele... handguards, then try GBLS DAS Barrel nuts. I've also tried out different parts: Magpul grip, SL-S stock and DD buttstock fit snuggly with no wobbling (much better than the original buttstock).

"Great gbbr stock. Great platform to upgrade on. The buffer and nozzle springs are the first things to switch out. Maybe add a Npas in to adjust fps. Can take real handguards and pistol grips. Lower receiver threading is a hair tighter than real buffer tubes so its very easy to thread a tap in and get a milspec tube on.

Some brands of GG cans and propane adapters work fine with the TM vent nozzle. For my own mags I cut AEG hop up nubs in half and uses those for orings in the fill valves.

Super accurate. Super fun. Highy recommend it

"Don’t get me wrong the gun is a 5/5, accurate out of the box and mainly the only upgrades you need for a while should be external accessories. Gun is good for all environments even outdoors.

My problem is not so much the gun itself besides the magazines being a little fragile. But over all I’d still give them a 5/5 just be careful with them. Where I got annoyed was when the armorer’s wrench it came with actually didn’t even fit and scratched my barrel (which is my bad) but I’d say have one ready that isn’t the one that came with the box. Don’t let my review be the reason you don’t buy this gun. I’d say YOU SHOULD BUY IT. Just be prepared to have fragile magazines and don’t be tricked into using the armorer’s wrench it came with
