I bought a MAK90 and the hammer rides the bolt down after firing so there is no trigger reset. It will fire once and reload but nothing else unless you manually cycle the action. It appears that the disconnector is not engaging the hammer at all. If I hold the trigger back and push the hammer back it just slides between the disconnector and trigger. Almost like the hammer is too short to fully reach it. If I release the trigger it will catch. I have attached a photo. Any help is appreciated. I am guessing someone in the past has "worked" on it.... new member but long time reader. Great information here!
