Despite trends towards low profile gas blocks and free float rails, there is still demand for the rugged A2 front sight block. Our A2 front sight FSB installation service can be done to any barrel with a .750 or .625 gas journal.
Whether you are doing a clone build or just want a solid backup front sight, we can mount it for you. Although we typically only stock F marked .750″ FSBs, we can special order other variants such as .625″, non F marked, shaved bayonet lugs, etc. Please contact us for more information before purchasing if you want one of these styles as pricing and availability can fluctuate.
We currently offer two options: You can provide your own FSB and related hardware, or we can provide an FSB for you.
Please include your upper receiver since variations in upper receivers and their index notch can cause misalignment of the front sight. We will also need your barrel nut, delta ring assembly, and end cap if applicable.
We can install FSBs on previously pinned barrels, however you will need to contact firstname.lastname@example.org to discuss your options.
