HIPERFIRE Mark 1 AK Single Stage 2lb Short Pull Trigger AK-47/AK-74 Black. When installing a Hiperfire trigger the safety is only engaged when the shooter pulls the trigger back this enables the shooter to pin their sights on the front sight and only has to worry about acquiring the front sight and executing the shot. As most AR-47 shooters know the second stage of the fire order is the most sensitive as it is the fire order so a slight over-travel must be expected. With this in mind Hiperfire designed a curved trigger surface that provides the smoothest and most predictable trigger break. Furthermore this curved surface makes it extremely difficult to glare or skim the trigger with gloves which is something every shooter hates. The use of a curved trigger with outserts or over-travel springs the trigger instead of being pinched as with traditional AR-47's. This causes the shot to be slightly more slack and harsh but this is a very small issue you will experience.
