Here's the deal. I have a standard A2 FSB that I want to remove, and replace with a low profile gas block/FSB with a rail on it. I understand that the factory FSB is custom fit / indexed to the barrel with two pins. Are there any railed FSB/Gas Block combos on the market out there which make use of set screws and can be installed without custom fitting or removing metal, and which are compatible with flip-up front sights and will reliably hold a zero? |
| You might want to check out PRI and Yankee hill machine, they both make a flip up sight/ gas block combo. They are both the clamp on style which are easy to install and adjust to zero the rifle. I happen to have the PRI unit and it seems to hold it's zero well for a back up sight. Hope the info was helpfull . PATRIOT ARMORY 07 FFL |

I'm looking into those. The price is making me raise an eyebrow though. How can these cost so much? Also, any advice on mounting something like a Burris black diamond when part of the rail is taken up by the ARMS BUIS? What type of mounting rings or risers should I be looking at? |
