The new Flamingo VSR/GBB Gen2 2021 version 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.


  • Maple Leaf Crazy Jets GBB/VSR - Suitable
  • Maple Leaf 6.02 Series GBB/VSR - Suitable
  • Morpheus Unbridged - 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, panthera 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.

    These are by far the most consistent and best hopping bucking. They make every weight I use fly true and straight. I also love the consistent molding I never have to worry about getting a bad bucking! The 50a works wond wonders in my mk23s

    I have this installed on my TM MK23 and paired with the Hadron H plate and TDC it produces consistent accuracy and range. An essential to any MK23 owner out there.
