Excellent GBBR out of the box
Review by
Having had probably close to a hundred AEGs over the years, this was my first GBBR. I chose TM over other brands due to their reputation for reliability out of he box and magical HOP unit.
The M4 MWS certainly doesn't disappoint. It is loud, kicks nice and hard and works reliably. Range is excellent, shooting upto 60 metres with .28g BBs. The field stripping is just like the real steel, magazines weigh as much as a fully loaded real steel and the Cerakote finish is very tough.
The only downsides are the price and availability of mags, and if you are used to AEG hi caps then the 35 round capacity will take some getting used to. That said, I use it predominantly on semi auto and still hold my own in games. It is a little gas hungry but that's the price you pay for the realism of a GBBR.

Any figures used are based on tests performed on the products when they are first listed. These can vary due to changes by the manufacturer, gas pressure, gas used and a number of other factors. All figures should be treated as an approximate guide and used for reference only. 

All listed FPS are +/- 5% due to differences from rifle to rifle. If you require a guaranteed FPS, please add an upgrade/downgrade option on to your product (this may cost extra).
