BOLT B4 FS URG-U(R) V2

Do you think recoil is only the domain of GBB weapons? 

Taiwan's BOLT company has taken AEG weapons to a new level. Their patented B.R.S.S. system perfectly simulates recoil, which is almost comparable to GBB guns and also imitatate movement of bolt carrier.
How is it possible? The recoil effect of the M4 series is achieved by the weight placed on the tube of the stock. This simple principle makes use of the piston movement which is not firmly connected to the weight. The patented solution does not increase stress on the gearbox.

If you are afraid of atypical mechanism, there is no reason. The gearbox in the weapon uses standard parts for gearbox version 2. However, question is whether you will have a reason to change it. In the gearbox you will find BOLT high torque gears, lightweight aluminum piston with full metal teeth, CNC aluminum piston head and cylinder head. Only the spring guide has a light adjustment for the B.R.S.S. system. In addition, the BOLT M4 series uses conventional AEG magazines. You are using everything identical to common AEG weapons. However, you will find a complete range of BOLT inner parts and magazines in our offer.

Of course, the externals remains true to Taiwanese quality. Beautifully processed full metal body, plastic grip, stock and metal handguard. You also get detachable sights and tactical grip. BOLT patch is small gift from producer.
