Spike's Tactical 5.56 NATO M16 Cut Lightweight AR-15 Bolt Carrier Group - Nickel Boron - $179.99

Description

The Spike's Tactical Lightweight Nickel Boron Bolt Carrier Group is perfect for your next race gun build! They have machined away excess material for reduced mass to help decrease lock time and reduce bolt bounce, allowing you to run your rifle faster when every hundredth of a second can be the difference between a podium finish and the bitter taste of defeat.
Just like their standard BCGs, the Lightweight has been fully magnetic particle inspected and high pressure tested to protect against material defects. The carrier is machined from durable 8620 tool steel and the bolt from 9310 tool steel for maximum service life. Almost every part has been treated with nickel boron to allow for easy cleanup of even the worst carbon fouling, as well as reducing the need for external lubrication thanks to the very slick finish. The gas key is properly staked, the extractor spring has been upgraded with an O-ring for increased tension, and the Spike’s Tactical Spider Logo is engraved on the right side of the carrier to show through the ejection port. Assembled BCG weighs 10.5 oz.
