Brand Mission

Bolt Airsoft (Taiwan) is a new brand company in Automatic Electric Gun industry; we provide AEGs with powerful recoil movement able to use low voltage batteries.
Bolt Airsoft’s goal is to design AEGs close to a real gun and to satisfy survival/milsim game players as well as military collectors.                          
Powerful recoil movement and quality of material used are the keys to maintain our goals on track.


BOLT AIRSOFT by Tomy Lee with the creation of B.R.S.S. system.  Production:B4A1(M4A1),R.I.S.,and B4 SOPMOD.


Business type changed from foundries to manufactory,and developing          new mod,parts,and also use new materials to enhance products quality.


BOLT AIRSOFT now has 30 variety models in M4 Series and SR47        Series.


BOLT AIRSOFT SR47 and SR16 URX3.1 had licensed under Knight’s Armament Co.



B.R.S.S. is a revolutionary design with International Patents Registered

With Tomy Lee’s knowledge, the development team at Bolt Airsoft has created a powerful recoil system called B.R.S.S – Bolt Recoil Shock System. B.R.S.S is a revolutionary patern, which usesof an outstanding design using kinetic energy produced by the piston’smovement, transfered to a Recoil weight in stock tube and subsequently generates a recoil simulation.
Such a new design has been gone through lots of various tests and finally led to B.R.S.S. birth !


Powerful Recoil Movement

B.R.S.S technology generates strong recoil power by triggering B4A1.The strong power can even stamp a nail into a wooden table. The feeling of stock punching back each shot is a real pleasure for owner who enjoys a “kick” similar to firing a real M4A1.

Low Energy Consumption

B.R.S.S technology provides great power recoil action even while by using Low Voltage batteries. Its unique design makes this AEG last much longer, with an outstanding reliability.

High Durability

B.R.S.S Gear are made of firm and strong materials, which makes B4A1’s gear more stronger to capable with strong recoil shock, which adds extension period of AEG’s life.

High Compatibility

B.R.S.S Gearbox system offers a high compatibility with other brands’gearbox parts. Over 90% of B.R.S.S. parts are compatible with those available on the market. 
This advantage grants players with lower costs and bigger choice on repairs, upgrades, modifications and customizations.


B.R.S.S. HEAVY is newly recoil system which has stronger recoil ability than B.R.S.S.!

B.R.S.S. Heavy is a new design for fixed stock models, for example: M16A4.
B.R.S.S. Heavy reacts with longer fixed stock tube and longer recoil hammer which brings more powerful recoil feelings to physical contact, and also currently the strongest recoil system of BOLT products.
