Introducing the Odin Works 6.5 Grendel Type II AR-15 Bolt Carrier Group – Nitride!

This top-of-the-line bolt carrier group features a full mass M16 cut carrier machined from case hardened 8620 tool steel and a bolt machined from 9310 super alloy steel with a Type 2 bolt face for enhanced reliability. Both the carrier and bolt are finished in advanced Black Nitride for low friction and high corrosion resistance.

Whether you’re looking to upgrade your existing AR-15 or build a new one from scratch, this is the perfect bolt carrier group for you!

Safety Note: Choosing 6.5 Grendel comes with an added complication. There are “Type I” and “Type II” bolt/barrel specifications out there, and you CAN NOT mix and match parts for each of them without risk of damage and/or injury. Type II is the most popular configuration, but pay attention to what you are buying! A Type I bolt won’t chamber rounds in a Type II barrel. Even worse, a Type II bolt mated to a Type I barrel will create excessive headspace and result in a dangerous rifle to fire.
