Is it possible to install an AR15 fixed front site block forward of where the actual gas block port is, for purposes of just using it as a fixed front site?
I don't understand how the pins and such secure the FSB to the barrel, so I'm not sure if it actually requires a female cut in the barrel where the gas port is, in order to be secured.
Or if I could (have a gunsmith) have a low profile as block installed under a handguard rail system, and then separately, install an front site block to the barrel forward of the handguard rail?
The purpose is to have a more secure front site than attaching a fixed front site to the pic rail of the handguard rail. Whether or not I need a more secure front site than a pic rail attachment is my personal preference, and I like the look better of the FSB set up. Just wondering if it's possible to attach one this way (assuming I have the correct FSB for the barrel outer diameter), or if the attachment will either fail, or be less secure, if it's not done over where the gas block cuts are on the barrel.
