For a lightweight BCG, you need look no further than this nickel boron bolt carrier group by Spike’s Tactical. This Spikes lightweight BCG is covered by the manufacturer’s Lifetime Warranty, proving that it is worthy to grace your prized AR-15 with its presence.

The Spike's Tactical Lightweight Nickel Boron BCG is specifically designed for those who desire to operate a lighter weapon system. Those of you who participate in three-gun competitions will appreciate the speedier cycling that a lightweight carrier group offers.

What Does The Spikes Lightweight BCG Offers?

This lightweight bolt carrier Group is precision machined to fit your AR15 and function flawlessly, but it has something more. The Spikes lightweight BCG is treated with Nickel Boron, a metal coating that protects the parts against corrosion and wear typically sustained by firearm components. It even makes the parts less susceptible to carbon fouling, which means you won't have to spend ages scrubbing away at this bolt carrier group to get it clean. The Nickel Boron coating imparts a permanent lubricant quality to the metal, eliminating the need to keep a layer of oil on the parts.

Finally, the Nickel Boron coating is hard enough to withstand heavy use without ever flaking or rubbing off. The bolt, carrier, extractor, cam pin, carrier key, and gas key have all been coated with Nickel Boron to make the toughest lightweight BCG around. As a matter of fact, government agencies and the military are adopting nickel boron as the ideal finishing material. Smoother than hard chrome, this finish will allow your rifle to cycle more efficiently and will never chip or peel. Nickel boron is easy to clean and enables your bolt carrier group to operate with minimal lubrication.
