Tokyo Marui CQBR Block 1 GBBR – Before You Buy

As some of you may know Instinct has been using a GBBR for about 6 months now. And since everybody in the team likes it so much, nearly everybody is getting one. As a matter of fact, Viper already got his one as well and thanks to that we’re doing a full in depth review of the Tokyo Marui CQBR block 1 GBBR.

So without any further ado, let’s open this box.

Inside the box

Inside the box we find the gun itself, a 35 round magazine, a Japanese manual with some paper targets. Furthermore we find a small bag of BBs, a red barrel cap, a front sight adjustment tool, a speedloader and at last a cleaning rod.

The Gun

As can be seen, this is an M4 model modified to a Close Quarter Battle Receiver (CQBR). The first thing we immediately notice is the high quality build as is to be expected from Tokyo Marui.

Dimensions & Weight

In overall this GBBR is an open bolt system that, fully extended, reaches out to 785 millimeters. The inner barrel has a length of 250 millimeters and the weight is just below 3 kilograms.

When it comes to the weight distribution of this gun, it is much more realistic in our eyes, compared to an AEG as mostly the mass is placed on a pistol grip because of the motor. With the GBBR the weight is more deviated between the barrel and the bolt.

Build

It’s clearly noticeable that this gun was built for a right-side dominant shooter, as the selector switch, the lever of the charging handle and the bolt catch are positioned on the left side, while the ejection port and the mag release are based on the right side.

Outside Features of the Gun

Cerakote Receiver

Covering the outside it has a nice metal receiver with a mil-spec Cerakote coating which has excellent scratch resistance. Also the Colt markings are integrated into the receiver as well, which add to that realistic factor.

Barrel & Handguard

The outer barrel which is made of metal has a length of 10.5″ inch, and the 1913 style picatinny handguard which is also made of metal has a length of 9″.

Buttstock

The gun features a polymer Crane style buttstock, which has 6 stages lengthwise. Notice that this is Tokyo Marui its own version of the Crane buttstock and an easy way of noticing is that QD swivels don’t fit the buttstock. Another thing is that the buffertube is neither mil-spec nor commercial spec, but something in between.

Also noticeable is that the storage space in the Crane buttstock isn’t easy accessible as it should be with a realistic one. To us, it looks like Tokyo Marui has used the designs of the Crane buttstock they made for the AEG NGRS series and placed them on this GBBR as well.

Pistolgrip & Sights

Furthermore we find a classic polymer M4 style pistol grip. In the front there’s a fixed metal front sight, which is height adjustable. On the back it features a metal flip-up rear sight which is both adjustable in windage and elevation, it has both a small and large sight for large and short distances.

Charging Handle, Sling Mount & Flash hider

On the back of the gun, it features a metal charging handle and on the back of the receiver it has a metal sling mount. If we have a look at the end of the barrel, you can find a QD M4 flash hider which can be turned on and off without the use of an allen key, to expose the 14 millimeter counter clockwise thread.

Frontgrip

In addition, this gun comes with a nice polymer frontgrip, which feels quite comfortable in the hand.

The Magazines

The magazine is a Stanag style aluminum die-cast magazine. It weighs about 400 grams, which represents a fully loaded real steel magazine. So, when carrying these you really need to consider how much you want to carry with you.

TIP: Magpuls

A good tip we want to share with you is to attach Magpuls to your magazines. This because gas magazines are sensitive to shocks and the magpuls will reduce these shocks partially if they fall on the ground.

Inside Features of the Gun

Easy to open & Hop-up

The gun has an easy and practical build which allows you to quickly open up the system to do maintenance. Or to do in field adjustments on your hop-up unit. By the way, the hop-up unit is supreme, as it is also built by Tokyo Marui.

The ZET system

As you may or may not know, Tokyo Marui has designed their own inside system. Which is called the ZET system. This allows for less wear and breaking of the bolt catch and has been tested up to 10,000 cycles without any performance loss.

Also due to the special built of the inside system, there is less burden on the inside parts that are usually caused by the bolt operation. By the way, the gun features a metal bolt with a plastic nozzle.

Performance of the Gun

Recoil & Selector Switch

The gun features a strong recoil and even when shooting at single shot you immediately notice when your magazines empty unlike with the AEG NGRS series. The gun also has a crispy selector switch, which can be placed on safe, semi, and full auto. Though the safety can’t be used until you pull the charging handle just like with a real gun.

The Trigger

The gun features a very snappy trigger and once you’ve taken a shot the distance to the trigger reset is very good.

Precision  & Range

We’ve already done our testing before in another video/blog in which we compared this gun to a Tokyo Marui NGRS. The results show that this gun has a maximum effective range of 31 meters when hitting a head sized target. When it comes to the precision of this gun, it is 55% less precise than the NGRS of Tokyo Marui, probably because of its heavier recoil.

But once it was cooled down it was 36% more precise than the NGRS. That’s probably because it was designed to work at these lower temperatures. As for the reliability, Instinct used the CQBR Block 1 and Instructor Delta used the MWS at 0°C with both still a solid performance.

Muzzle velocity

The gun uses green gas as propellant and when it comes to the FPS, we tested it a while back in about 15 °C. The velocity of this gun with 0.28g bbs was about 280 FPS very consistently. Now, if you go to lower temperatures, you might want to use higher pressure gas.

Magazine Issue 

That aside, the magazines sometimes have feeding issues. The issue that sometimes occurs, is that the feeding spring gets stuck. To resolve this problem, you can use tweezers to push the BBs down and the spring will come free again.

Final Thoughts

Cons

  • The Crane buttstock is not an exact replica of the real buttstocks and in the way it comes it’s just not really useful. The pistol grip itself is a standard m4 pistol grip and these are always quite uncomfortable. Luckily, there are enough aftermarket parts and even real steel parts that fit is gun.
  • The issue that tends to happen with the magazines is easy to fix, but it’s pretty annoying because you don’t know when it stops feeding. 

Pros

As for the positives of this gun, the features and handlings are much more realistic compared to the NGRS of Tokyo Marui. The recoil is something you really have to fight against, and it is a very tough built system. In overall the performance of this gun doesn’t differ much from the NGRS, but the realistic recoil and added features really add to the sport and training purpose of this gun.
