The new Flamingo Noir VSR/GBB bucking from SniperMechanic. 
 
This bucking will fit any rifles/pistols that use the VSR/GBB style bucking.
 
This bucking uses the same tried and true design of the Flamingo bucking, but using a NBR based material vs the silicon. This is in part due to people requesting it and also from testing materials in higher power/higher ROF builds.
 
These bucking's are incredibly durable, seal very well and are suitable for high ROF and high power builds, especially GBBR's due to their more aggressive nozzles movement.
 
Due to the durability/toughness of the material these buckings do have a bedding in period which can be 100-150 round/ a few magazines, this is to allow the material to conform and fit to the chamber and nub being used.
 
This is designed for GBB/UNBRIDGED barrels
