I was trying to upgrade my Bushmaster Carbon 15 with a new handguard from the original standard issue handguard. I bought a Yankee Hill Machine quad rail that had excellent reviews. After getting to the point of threading on the new handguard, I found out the threads don't match. Called YHM, and they informed me that the handguard only fits mil-spec uppers.
Just curious if anyone knows of a solution to make this one work, or a recommendation for a different handguard that is similar to a quad rail?
