Frequently Asked Questions
What is a bolt head and why would I need a replacement?
The bolt head is the front section of your bolt carrier group that engages the ammunition and controls headspace. Over time or heavy use, bolt heads can wear, or you may simply want to upgrade to a quality aftermarket component like Seekins Precision offers.
Will these M3 bolt heads fit my AR-15?
These are M3 standard bolt heads, so they are designed for bolt carriers configured to accept M3 bolt head specifications. Check your carrier's documentation or contact Seekins Precision directly if you're unsure about compatibility with your specific platform.
Do I need any special tools to install these bolt heads?
Installation typically involves removing your current bolt head and replacing it with the new one; however, the specific process can vary depending on your bolt carrier design. Consult your rifle's manual or reach out to a gunsmith if you're unfamiliar with the procedure.
