what magnification is your optic? at 4x or better i can't even see the front sight
what does your AR look like? what is the configuration?
Here's a pic. I mainly use this as my long range bench / prone gun becasue its too heavy for anything else.
I like your idea, but I’m hesitant to start messing with the gas block because this barrel is non-standard and I'm only a little familiar with upper construction. It’s a Colt Competition HBAR. I would very much prefer NOT to destroy the front site. Another problem is that this is a "post-ban" upper with a welded on break.
As far as not seeing the front site, I’ve heard people say this before, and it’s semi-true. But the “ghost” of the front site is always there and seems to dull and blur my scope vision. It’s not immediately apparent but seems to cause me eye strain.
