Frequently Asked Questions

What is the BCM SOPMOD Bolt Upgrade/Rebuild Kit and what does it do?

The BCM SOPMOD Bolt Upgrade/Rebuild Kit is a $30 kit designed to enhance the reliability and longevity of AR-15 bolt carrier groups, particularly budget-friendly ones. It replaces the extractor, spring, O-ring, and gas rings with upgraded components.

How do I install the new extractor from the BCM kit?

After disassembling the bolt, install the new spring and insert into the BCM extractor. Then, seat the O-ring over the extractor. Reinstall the extractor into the bolt, compress the spring and O-ring, and drive the extractor pin back in until it's fully seated and flush.

How can I check if my AR-15's gas rings are worn out?

To check for worn gas rings, pull the bolt completely out and set it on a flat surface. If the weight of the bolt carrier causes the bolt to collapse inward, your gas rings are worn and need replacement. New rings will not collapse under the bolt carrier's weight.

Is the BCM SOPMOD Bolt Upgrade Kit worth the cost?

At approximately $30, the BCM SOPMOD Bolt Upgrade/Rebuild Kit is considered a worthy upgrade for most AR-15 bolts, offering a cost-effective way to improve extraction reliability and overall BCG longevity compared to buying a completely new bolt or BCG.
