Adventure Force Brute Pro Varuna Kit

The Varuna Kit

This kit was purpose built to add modularity and function to the Adventure Force Brute Pro. 

Customize to fit any play style. Want a extended pistol build? Just use the collet shroud. Need a full size primary blaster? Print the full kit and pair with a picatinny stock.  

Update log

• 11/21/25: Added adjusted versions of the shroud and top rail to fix a tolerance issue. 

Features

• Two T-Pull priming options (Bearing assisted and Mini) 
• Modular Collet Shroud (with quick swap barrel system) 
• Foregrip Magazine Holder 
• Picatinny Stock Attachment 
• Raised Sight Mount  

Hardware

Uses a mix of M3 hardware, original screws from the blaster and printed pins. 

• 4 M3x6mm screws 
• 2 M3x8mm screws 
• 2 M3x16mm screws 
• 2 M3x20mm screws
• 8 M3 hex nuts 
• 6 printed pins 
• 4 Toy Screws (reuse the original) 

Instructions 

Install procedure is very straight forward. Reference the model descriptions for hardware locations and a basic guide. 

Only requires minor trimming of the protruding clear plastic underneath the original priming handle. 

If you have any questions, feel free to contact me. 

Support and Printing

All models are oriented how I printed them but you may have better luck with a different orientation. Printed in Elegoo Pla+. 

Parts that require support: 

• Brute_Shroud
• Brute_ShroudAdjusted
• Brute_StockBase (Tree) 
• Brute_TPullBase
• Brute_ShortyTPull
• Brute_BearingTPull
• Brute_Grip

Your foregrip will have a more refined shape than what is pictured above. Photo below is how yours will look. 

Helpful Information

Adjust the scale of the printed pins in your slicer if they are too tight or loose. 

M3 hardware can be used instead of the printed pins for added rigidity.

*For long term use, a m90 airsoft spring is highly recommended. This still gets 120 fps but with a much more comfortable prime*
