I got another AR with a typical front sight with the gass block built in. Can I just purchase a clamp on gas block and swap them? Or do I have to purchase a different gass tube?
You can take off the A2 front sight you have now and put on a low pro gas block using the same gas tube. Just have the right tools and it's an easy job!
PM a mod and ask them to close this one. But most people will see you found your answer when they read your last post. The thread will die on it's own I'm sure.
