This model was designed to be a drop in part for the GHK-G5 GBBR platform. When printed with PLA, and PLA+, the rate-of-fire is significantly increased, while still offering modest durability. 
It is recomended that the part be printed with the back of the bolt carrier on the print bed, allowing for a better seal between the cylinder and piston.
 
This is the standard resolution of the file and may require some extra post processing to ensure compatibilty. Sanding of the rails and cylinder is recommended for the smoothest performance. Lubricate using silicone or lithium based lubricants. ALL money earned from paid models goes directly into making better models for the community.
