Pencil profile barrel?
William W on Feb 11, 2019
BEST ANSWER: Pencil profile means it is a thin barrel (ever heard of pencil thin?). When the AR10 was originally conceived it had a pencil barrel but due to 1960's manufacturing techniques and a poorer understanding of stress relief the barrels would become inaccurate as they heated up (pencil barrels heat up quickly). Modern manufacturers claim they have mitigated this and that pencil barrels should only move the center of your group a tiny bit as they head up (Faxxon managed a 1 MOA shift).
What is the inner diameter of the handguard?
