The Boomfab Titane Bolt Carrier Group is allegedly the lightest carrier on the market. I've personally not familiar with Boomfab or their products, but check out all of their other offerings here.


Description:


The BOOMFAB Titane carrier is a CNC machined, ultra-light weight titanium AR15 bolt carrier designed for competition use. Its design results in faster shot recovery, increased cycling speeds and minimized muzzle movement.


Specifications:

•Multiple proprietary heat treatings result in an extremely durable carrier with a long service life. We have Titane carriers with over 10K rounds on them running in professional shooter’s rifles.
•Designed with increased carrier bearing surfaces for smooth operation.
•Fully compatible with standard mil-spec AR15 bolts, cam pins, firing pins and retaining pins.
•The Titane carrier comes standard with a pre-installed mil-spec gas key and staked torx fasteners.
•Optionally, the Titane carrier can also be purchased as a complete bolt carrier group which includes a mil-spec HP/MP tested C158 steel bolt, firing pin, cam pin and retaining pin.
