The CM005 seems to be based on an M4 CQBR, which is a shorter and smaller version of the classic M4.
The CQBR version of the M4 is made to be used inside vehicles, by bodyguards, or by special forces teams boarding ships and breaking into buildings. The lower receiver of the CQBR is the same as that of any military M4, and the actual "CQBR" comes as a separate upper receiver that attaches to a donor lower. This lets special forces troops keep their own weapons and just change them to fit the situation.
The gun was made in 1999 and put into use in 2000. There are now more than 10,000 CQBR M4s in use with the different branches of the military. The MK18 is the name of a full set of weapons. Mod0 had a lower receiver and a CQBR upper section. This is what most soldiers are given instead of just the upper section.

This replica is one of the better M4s for low- to mid-level players, and it's a great place to start if you want a reliable, upgradable CQB gun. Because CYMA is so compatible with other brands, this rifle can use any off-the-shelf upgrades, including internal parts like pistons and triggers and external parts like aftermarket barrels and furniture. In the world of airsoft, M4s are sometimes seen as boring because everyone has either owned one or used one at some point. However, because they are so popular, there are more modifications for airsoft M4s than any other weapon on the market.

The higher-end weapons made by CYMA, like this one, are made of very good materials. The bodies are solid and don't move or give at all, and the furniture feels very comfortable (and sturdy). This rifle has a slightly different frontal RIS section. It looks like a normal M4A1 railed handguard, but it also has a "clamp" that holds the rail to the upper receiver so it doesn't move side to side. This means you can attach a vertical grip or something similar and run around all day with this rifle without worrying about accidentally loosening your handguard.
When it comes to accuracy, this weapon more than meets the needs of a CQB or scouting rifle. It can hit a man-sized target at about 30 feet, but if you want to use it for very long-range field engagements, you might want to buy a better hop-up rubber, since the shorter barrel isn't made for precise accuracy at long ranges.
Overall, this is a great weapon for CQB or as a lightweight scout weapon for field combat. Its small profile lets you run through woods and over obstacles without worrying about knocking your gun. It also lets you move quickly from target to target when hiding in a tree, since the barrel won't get caught on the branches.
