Frequently Asked Questions

Why is dimpling an AR-15 barrel important for gas block installation?

Dimpling ensures the gas block is perfectly aligned with the barrel's gas port. This precise alignment prevents the gas block from shifting under recoil, which is a common cause of short-stroke malfunctions and ensures consistent gas delivery for reliable cycling.

What are the risks of not properly dimpling an AR-15 barrel?

Improper alignment or a loose gas block can lead to short-stroke malfunctions, failure to feed, and inconsistent cycling. Using the gas block as a jig is dangerous and can permanently damage the barrel, making it unusable.

Does Sons of Liberty Gun Works offer barrels that don't require dimpling?

Yes, all Sons of Liberty Gun Works barrels come pre-dimpled from the factory. This guarantees correct gas block alignment right out of the box, saving time and ensuring reliability regardless of your final rifle configuration.

What materials are recommended for securing a gas block after dimpling?

For a secure and permanent installation, it's recommended to use knurled head set screws and a high-strength threadlocker like Loctite 271 Red. This combination prevents the set screws from backing out due to vibration and heat.
