Tps Arms Ar-15 Enhanced Trigger Guard Billet Aluminum. The vertical bar is long enough to accommodate over sized magazine release button allowing the user to quickly engage/de-engage the mag release with one hand. This new vertical bar can also be used to support the safety on the opposite side of the trigger guard for even more strength. For the safety a hammer is needed that has a rounded surface to prevent finger travel damage. Typically plastic K products have a rounded profile due to molding issues or just not being sharp enough to cut your trigger guard without causing damage. Due to the machining involved in machining we HIGHLY recommend a forged or forged receiver with a drilled and tapped hole in the trigger well area. Also make sure you take off all pins and springs prior to attempting to install the trigger guard. Due to the numerous benefits it is highly recommended that the guard is installed by a competent and qualified gunsmith with an understanding of the workings of the gun before installation. Failure to install the trigger guard correctly could lead to serious injury or loss of function.
