BBA VFC KS1-EVO One Piece Hop Arm

WARNING - PREORDER NOW - END APRIL DELIVERY 

Take your VFC EVO hop chambers performance to the limit with the BBA VFC EVO One Piece hop arm!

A drop-in replacement for the standard arm + nub which gives consistent pressure vertically down onto the hop bucking, this leads to increased accuracy at longer range (40m+) and generally more consistent performance.

Fits all VFC EVO Hop chambers which are included in the below models (Most are unreleased as of March 2026):

• VFC KS-1 
• VFC KS-3
• VFC MAXIM Defense PDX SBR 
• VFC URGI EVO 
• VFC BCM EVO
• Marksman MK12 MOD 0  

Whilst it will improve accuracy with the stock bucking, we highly recommend you replace the included VFC Black Hop up bucking to further increase performance! 

We've had great results with the 4UANTUM GBBR Bucking

Will NOT fit any other hop chambers including the V3 Rotary/GHK/4UAD Magnus Pro
