Odin Works ACC223BCG AR-15 Bolt Carrier Group

Odin Works AR-15 Bolt Carrier Group: Reliability Built In

The foundation of any reliable AR-15 is a properly manufactured bolt carrier group. The Odin Works ACC223BCG delivers mil-spec performance with attention to detail that separates quality components from the merely adequate.

Construction and Materials

This bolt carrier group is built from case-hardened 8620 steel with a black nitride finish—a low-friction coating that reduces the need for constant lubrication while providing superior corrosion resistance. Every component meets or exceeds military specifications:

• Bolt Carrier: Case-hardened 8620 steel with black nitride finish
• Bolt: True mil-spec dimensions, case-hardened 9310 steel, CNC ground external surfaces
• Gas Key: 4130 steel, properly staked into a milled valley with Grade 8 hardware
• Firing Pin: Mil-spec 8740 steel, center-less ground and hard chrome coated
• Cam Pin: Hardened 4340 steel
• Extractor: 4340 steel with mil-spec spring and O-ring combination

Quality Assurance

Odin Works subjects every bolt carrier group to magnetic particle inspection and high-pressure testing before it leaves the factory. These are not cosmetic checks—they ensure your rifle will function reliably when it matters.

Fit and Function

Designed for AR-15 and M4-compatible rifles, this bolt carrier group drops into any standard receiver. The black nitride finish provides a professional appearance while delivering genuine functional benefits.

Made in the USA by shooters who understand what reliability means.
