What is the BRAVO COMPANY - Lower Group w/MK2RMS-M1T & Stock Mod-0 Blk?

Bravo Company introduces the BCMGUNFIGHTER™ Stock. The strongest light-weight polymer stock available for your mil-spec receiver extension is here!

Snag free Design. No sharp edges prevent tangling of the rifle with the shooter's sling, molle gear, or other kit. Modular VBOST (Vehicle Borne Operations Sling Tab) This tab interfaces with the shooter's riggers' band or bungee to secure the shooter's sling against the stock when the carbine is not in use. Increasingly, this is the most common application when operating inside a vehicle.

2 different types of ambidextrous sling mounting options, including QD swivel sockets.

Simple modular design. 5 parts, and 1 screw allow for modular adaption of future stock options and configurations.

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

Excellent complete lower
A parts list that covers it all. Very good milspec trigger, A5 length buffer tube, a T0 A5 buffer that can be made whatever weight wanted and a good Gunfighter stock. I added a 15% stronger buffer spring and made a T1 buffer. A 13.7 SOLGW upper locks tight, shoots very soft and functions all the way down to Wolf steelcase and PMC bronze.

Too Much Wobble
Bought this lower for my 11.5" BCM MK2 upper and it has a significant amount of wobble between the two receivers. I then tried different brand uppers in the same lower and still had the same amount of wobble. I would expect better from BCM, especially spending $550.00 for a lower.
