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.
Attention: The set does not include a battery or a charger.
The set includes:
- replica
- magazine
- User’s manual
Battery included![]() NiCd
rechargeable battery is characterized by high efficiency
current-carrying capacity, but there are disruptive effect on memory.
Should be unloaded and loaded in the full cycle, ie, it is recommended
to fully discharge, and after unloading must charge the battery
immediately without leaving it for a long time in a discharged state. | No |
Blow Back![]() Blow back is a simulation system of the cocking lever - it imitates the work of it as the equivalent sharp. This system raises the realism and adds a lot more experience during shooting. | Yes |
Product length [cm] | 90 |
Product weight [g] | 3335 |
Power supply | Electric |
Material | Metal Plastic |
Muzzle velocity [FPS]![]() It is the spped of bb, while its leaving the innerbarrel of replica. This speed is measured in FPS (Feet Per Second). 1 FPS = 0,3 m/s 1 J = 99 m/s 1 J = 326,7 FPS | 430 |
Fire mode | Full-auto Semi-auto |
Gearbox version![]() Indications v2, v3, v6 does not mean the level of advance, but only shape of gearbox skeleton which was used and selected by the manufacturer depending on the capabilities of the body of the replica. For example, a models of the M4/M16 family, MP5, have a v2 gearbox, while the AK family have gearbox v3. | Gearbox v2 |
Hop-Up![]() Hop-Up system is used for overclocking bb during the shot (putting it in rotation), through which, it extends its flight path. Acting laws of physics make that bb lift up, while the gravitational force take it down. Appropriate adjustment of Hop-Up, will compensate for these two factors, which result in long and straight flight for longer distance and be greater focus shot (to improve accuracy). | Yes |
