We also make an adjustable safety selector to cover everything in between.  Specifications for HIPERFIRE Xtreme AK Mark 3 Single Stage 2lb Short Pull Trigger: Manufacturer: HIPERFIRE Color: Silver Finish: Nickel Boron Trigger Shape: Flat Trigger Pull Weight: 2 lb Gun Make: Kalashnikov Gun Model: AK-74, AK-47 Gun Type: Rifle Condition: New Height: 0.8 in Length: 6.45 in Features of HIPERFIRE Xtreme AK Mark 3 Single Stage 2lb Short Pull Trigger Improved single-stage creep or pre-travel Lightened trigger pull weight through precision manufacturing and design, and lower friction coefficient (less drag) Flat trigger bow HIPERSHOE finger pad reduces the perceived trigger pull weight for a lighter feel, and offers 6 positions for adjustability to fit the users personal preference Package Contents: HIPERFIRE Xtreme AK Mark 3 Single Stage 2lb Short Pull Trigger Hipershoe This product is compatible with the following gun models: AK-47, AK-74
