Frequently Asked Questions
An M4 designed for Close Quarters Combat by D-Boys. This replica is intended for engagements in confined spaces. The front RIS allows for the attachment of a wide range of accessories such as tactical flashlights, lasers, or grips for a more secure hold. The metal construction provides a feeling of compactness and increased durability in the field. The accuracy and grouping of the replica are acceptable, but let’s not forget, we are talking about a replica intended for tight spaces. The internals of the replica, when properly maintained, have a fairly high autonomy.

Product Description
Presentation
As the world modernizes, spaces are becoming increasingly crowded. Thus, the cases where the M4 was the shortened version of the M16 have reached a point where the M4 is again too long, leading to the creation of the M4 CQB with an even smaller size using lighter alloys to allow for better maneuverability in tight spaces.
Exterior of the replica
Therefore, we present the airsoft replica M4 CQB RIS manufactured by D-Boys. Made entirely of metal, it features 22mm rails on the front to attach accessories such as flashlights, lasers, or advanced sighting systems.
Interior of the replica
The length of the inner barrel has decreased along with the shortening of the outer barrel from 363mm to 280mm, which does not necessarily mean a bad thing; accuracy does not seem to be drastically affected by this aspect. However, for those who are not entirely convinced they want an authentic M4 CQB, they can always opt for the installation of a precision barrel of 363mm with the included adapter, returning to the original dimensions of an M4A1 but with the advantages of the RIS replacing the classic ABS handguard.
The gearbox of the airsoft replica is version 2 with 7mm bearings, and most of the internals are made of metal; piston head, cylinder head, and spring guide, which is also equipped with a bearing for better performance. The airsoft replica has a ball speed of approximately 115 meters per second measured with 0.20g BBs. It is recommended to use 0.25g BBs.
Power Supply
The battery is located in the Crane stock. Included in the package is a 9.6V 1200 mAh Ni-Mh Crane battery. A Li-Po battery can be used, but it must not exceed 7.4V and 2800mAh in Crane shape or 7.4V and 1200mAh Stick. The maximum allowed battery must not exceed 9.6V.
