For sale Rifle Bolster Tuned CYMA CM.113B AKS-74U Zco Custom AEG – Upgraded / Excellent Condition / Accessories Included

For sale is my Bolster Tuned CYMA CM.113B AKS-74U Zco Custom AEG, in excellent condition and only used around 5–6 times.


This is the professionally upgraded Bolster Tuned version rather than the standard CM.113B, with a very strong internal setup and excellent trigger response, rate of fire and range.


Key upgrades/specification include:

• Full metal construction
• Gate ASTER ETU with EXPERT firmware
• Warhead 27K Brushless Motor
• 4UANTUM Friction Pro High-Performance Hop-Up Bucking
• Bolster Armouries EZO bearings
• Bolster Armouries AOE Correction Washer
• Bolster Armouries AK Trigger Spacer
• Gate Power CNC Aluminium Hybrid Piston Head
• Gearbox internally refined and polished by Bolster Armouries
• Compatible with 11.1V LiPo batteries
• Very fast semi-auto trigger response
• Approx. 26 rounds per second according to the original specification

Performance is excellent. The upgraded hop system provides very good usable range, and in my experience it performs comfortably at around 60 metres and beyond, depending on BB weight, hop setting and conditions.


The rifle has had very little use and is in very good cosmetic and mechanical condition.


All accessories shown in the photos are included with the sale.


I’m only selling because I’m moving abroad soon and unfortunately can’t take my airsoft equipment with me.


Happy to provide additional photos or details if required.
