The GBF (gas block Forward Controls) is a precision engineered 0.750 gas journal gas block, crafted with the hallmark meticulousness of Forward Controls Design. Constructed from heat treated 4140 bar stock, the GBF is finished with a manganese phosphate coating, ensuring durability and resistance to wear. This gas block is designed with tight tolerances to maximize the seal and performance, embodying a commitment to quality and functionality. One of the standout features of the GBF is its semi-blind gas tube hole, a thoughtful innovation inspired by the late Will Larson of Semper Paratus Arms. This design includes an access port just large enough for a 3/32 punch, allowing users to easily dislodge a gas tube that may be stuck due to carbon buildup. This feature minimizes the size of the gas tube hole, enhancing the overall efficiency and reliability of the gas block. Additionally, the GBF is equipped with bosses on both sides, providing gunsmiths with convenient reference points for pinning the gas block to the barrel. This thoughtful addition simplifies installation and ensures a secure fit, making the GBF an ideal choice for those seeking precision and ease of use in their firearm components.
