The new Flamingo Noir VSR/GBB bucking from Sniper Mechanic.
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 nozzle 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/VSR cut barrels, unbridged only.
The Flamingo Noir comes in 60A and 70A, most sub 2.5j builds will work perfectly fine with the 60A, for GBB rifles or high power builds the 70A may offer more consistent results.

Compatibility:

Maple Leaf Crazy Jets GBB/VSR - Suitable
Maple Leaf 6.02 Series GBB/VSR - Suitable
TNT Barrels Unbridged - Suitable
LayLax Unbridged- Suitable
Action Army Unbridged - Suitable
PDI (Genuine ones) Unbridged - Suitable, but very tight and need the use of an Omega nub due to tiny window
PDI Clone style barrels - Untested
EdGi Unbridged- Varies, some hop windows were suitable during testing, others were not as the window was shallow/too short.
Lambda Unbridged - Suitable
Other Unbridged Stock Barrels - most stock barrels won't fit due to the narrow width of windows, especially on WE/TM

Install tips:
For best results use on a barrel with a large window
Use a suitable concave nub in rifles, such as T-nub, Omega Nub, Bridge nub, H nub, gunsmithy TDC.
For pistols, the standard V shape arm gives great accuracy, but for the best range use a Hadron H Plate or Maple Leaf Key.
PTFE rear of bucking.
Lube outside of bucking when installing into tight chamber as the material is very grippy.
