This guide details the Vang Comp modification for the Remington 870, focusing on the technical aspects of barrel porting and lengthened forcing cones. Expertly explained by Garand Thumb, these modifications are shown to significantly reduce felt recoil and improve shot pattern consistency, making it a top-tier combat shotgun. The process enhances reliability through internal polishing and timing adjustments.

This video explains the technical differences between back-boring and over-boring shotgun barrels. While both increase bore diameter, over-boring is more common and involves a slight increase (e.g., 18.6-18.8mm), whereas true back-boring is a more significant modification starting from the chamber. Potential benefits like reduced friction and improved patterns are discussed, but the speaker emphasizes these gains are often marginal and marketing-driven, with some experienced shooters preferring standard bore sizes.
