Ryohin Buhin Tokyo Marui MWS Compatible T8 Adjustable Recoil Buffer Recoil Spring Custom Kit V2 with Adjustable Spacer (for TM GBB M4 Series)

Compatible Airsoft Guns: Tokyo Marui Gas Blowback Machine Gun (GBB) M4 Series (M4A1 MWS / M4A1 Carbine / CQBR Block 1 / Mark 18 Mod 1 / MTR-16) This is a T8-made variable recoil buffer custom kit for Tokyo Marui Gas Blowback Machine Gun M4 Series. This set includes a buffer spring, variable recoil buffer, and two types of adjustment spacers, allowing you to instantly upgrade your recoil-related components!

Variable Recoil Buffer: Up to six weights can be inserted into the buffer, allowing you to adjust the weight from 30g to 80g to suit your preference! (The stock recoil buffer is approximately 23g.)

Reinforced Buffer Spring: This hard spring is 120% stronger than the stock spring, increasing bolt forward speed. The increased speed before the next round is fired results in a sharper shot, and the sluggish feel of the stock spring is eliminated, making bolt operation more enjoyable! *Because extra power is required to retract the bolt carrier, fuel economy and performance in cold environments will decrease. *This is an internal part of the GBB. Installation requires knowledge of disassembling and adjusting airsoft guns. For advanced users.
