I am permanently crippled from a wrongly installed K98 trigger. I would STRONGLY recomend you have it inspected by a gunsmith before field use!
The issue that got me was with 5 rounds in the mag they put just enough upward pressure in the bolt to let the bolt slip past the shear catch on the undersid when the rifle was accidently droped. The safety was like that of a Rem 700 off the the side and the factory k98 saftey was removed. The rifle was build over 50 years ago and did not have an extra bolt stop pin like rifles today. It just stoped the trigger from moving when the safety was engaged.
Know what you are doing and know the other modifications made to the rifle and how they may effect the firearm. Not just for you but the next user or owner.
