A friend of a friend sent me this info and so far I have not seen it posted anywhere else yet. Looks like Bravo Company USA has released their new BCM MK2 Recoil Mitigation System on their website. The new kit consists of a slightly longer receiver extension with 8 positions paired with a slightly longer spring to help reduce bolt bounce and felt recoil. The BCM MK2 Recoil Mitigation System Mod1 kit is available in 3 different buffer configurations (T0 – 3.8oz, T1 – 4.7oz, T2 – 56oz) with T3 – 6.5oz and T4 – 7.4oz buffers sold separately.  

Complete Kit Features:

  • Lessens felt recoil, without compromising reliability
  • Provides a more consistent carrier velocity, which can aid in accuracy, reliability over conventional carbine buffer system
  • Increased internal counterweight travel reduces bolt bounce
  • Internal spring to reduce noise of counter weight shifting and ensure more consistent weight placement
  • Mil-Spec M16A4 rifle spring with more spring coils than M4 carbine, increases consistency and widens operating envelope
  • Buffer made of 7075T6 aluminum, hard coat anodized for lasting endurance. Comprised of Mil-Spec components
  • BCM US Patent #10415907

This kit contains all the necessary parts to mount to your Mil-Spec dimension stock assembly to your Mil-Spec lower receiver.

  • MK2 Mod 1 – T0 Buffer (weight = approximately 3.8oz)
  • Mil-Spec M16A4 rifle action spring
  • Mk2 Receiver Extension (approximately 3/4” longer than carbine), 7076T6, 8 position, Mil-Spec diameter
  • Lock Nut (Castle) M4
  • Receiver QD End Plate (include mount for QD swivel)

(PLEASE NOTE:  because of the MK2’s longer length some Mil-Spec stocks may not completely collapse closed all the way up to the M4 Lock nut.)
