BOLT B4 DEVGRU Extension / Black

BOLT DEVGRU EXT (B.R.S.S.) Carbine Replica

B4 DEVGRU EXT (B.R.S.S.) carbine replica by Taiwanese BOLT Airsoft company is undoubtedly a significant step forward in the evolution of AEG replicas. Due to implemented innovative solutions, it was finally possible to mimic the experience of using a GBBR type replica in a AEG type replica. In short, BOLT Airsoft was able to create an assault rifle replica that truly has a “kick” that it should have.

The replica was made from high-quality materials with the utmost care for details. All metal elements were made of aluminum. Furthermore, some elements were made of steel. These include: the flash hider, magazine and stock mounting ring. The alignment of elements is not a subject of any concern. There are no loose spots, especially between the upper and lower receivers, which is characteristic for “top shelf” replicas. An interesting solution is also the inconsistent paint job of the replica. Instead of a deep black color often seen in replicas, here we have different shades of black and a barrel and many other small elements in a steel color. This allowed bringing the appearance of the replica closer to that of the original, giving it a more realistic look. This effect is further reinforced by the use of a paint that gives the surface a grainy texture.

The replica features a multi-position, telescopic EMOD stock - featuring a thick, rubber stock pad and sockets for the attachment of a QD tactical sling. The stock features also a compartment for spare batteries or small items. The top of the replica has a RIS 22 mm rail that allows for the attachment of additional accessories such as iron sights included in the set. The handguard with 22mm RIS rails one each side is also equipped with a grip that enhances the handling of the replica. 

The greatest asset of this replica is undoubtedly the recoil and bolt operation simulation system. It consists of two independent elements: a standard bolt operation imitation known from a majority of EBB replicas and a separate system installed inside the stock slide. This system consists of springs, an inertia element and a system that transfers the energy from the piston to the inertia element. The experience offered by the implementation of this solution cannot be compared with anything else offered so far by other serial manufacturers of AEG replicas. An important fact is that due to certain construction differences resulting from the implementation of Blow Back system, the replica is to a large degree compliant with the V.2 standard set by TM. The only important difference is the piston with a characteristic notch. It is, however, equipped with an array of metal teeth, which guarantees a significant durability. The compatibility of remaining parts of the gearbox guarantees an easy tuning as well the access to spare and maintenance parts if needed. A high-quality Hop-Up chamber in combination with a 6.01 mm precision barrel guarantees an excellent performance.
