ALG Defense AK Trigger Ultimate with Lightning Bow (AKT-UL)
The AK Trigger Ultimate with Lightning Bow (AKT-UL) is a single stage trigger is designed for the AK47 and AK74 variant platforms.
The ALG Defense AK series of triggers were designed to work with most AK variants without fitting. With AK variants that have a rivet for the rear of the trigger guard, commonly acting as an anti-slap feature, this rivet should be no greater than 0.062 inches tall. Our AK series of triggers are designed to work with rivets that are 0.062 inches in height or less. If this rivet is higher than 0.062 inches, the rivet will have to be shaved down to allow for more clearance. Having improper clearance can result in damage to the disconnector itself.
Alternatively, if the user does not choose to modify the rivet, you can opt to modify the underside of the disconnector to increase the clearance between the bottom of the disconnector and the rivet in the receiver. It is not recommended to completely remove the tail of the disconnector as adverse issues may arise, such as trigger slap. Most users prefer to bevel (angle) the disconnector in the area that would contact the rivet. We recommend shaving down the rivet, not the disconnector tail.
Please note, we do recommend having a qualified gunsmith install and perform all fitting of fire control groups. AK receivers and parts coming from a wide origin of manufacture vary, there is no agreed upon set specifications. As such, fitting may be required. Please note the rivet and/or disconnect will need the proper clearance as per the chart below, failure to have the correct clearance will cause damage.
