The new Flamingo VSR/GBB Gen3 (2023) bucking from SniperMechanic. Improved contact patch, placement and materials.

This bucking will fit any rifles/pistols that use the VSR/GBB style bucking.

This bucking was a long time project in the making, one of the earliest but most challenging. However it's here and it's unique design and material offers great shot to shot consistency and a very flat flight path.

What makes the Flamingo bucking unique, more so than it's design is the material itself.

This is designed for GBB/VSR cut barrels, UNBRIDGED ONLY

GEN 2 - Improvements

The Gen 2 buckings are now made by a new factory, using a new mould process and material. The design has also been tested and tweaked to suit unbridged barrels for the most consistent contact width and length. These will no longer be suitable for bridged barrels.

The Gen2 Flamingo comes in 50A and 60A Shore, 50A is suitable for pistols and sub 400 builds, the 60A is for anything else.

Gen3 (2023) - Additional Improvements

Optimized patch radius
Improved feed lip angle
Improved rear sealing
Patch size increased to suit full open window barrels


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 he 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/to 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.
