Looking for a front sight base for a pencil barrel.  Its for a colt sporter lightwieght, preferably without bayo lug, but I'll take anything at this point.  I have been searching for 3 hours online, no luck.  If anyone knows of a source I would really appreciate it.  The very few FSB's I have run across are for standard or bull barrels.

Give Bushmaster a call. They sould be able to help you sence they have a lightweight barrel with the same profile as a Colt lightweight barrel.

According to their catalog, they do not sell sight bases separately.

Having said that, the chances that you will get an FSB that will align correctly and not be canted are slim.  I've never had much luck replacing pinned FSB's.
