You are DOOOOOMED!
All you need to get out of mauser Sporter Building Purgatory is to buy the following parts and complete a few simple tasks.:
A sporter stock
A sporter trigger
A safety to clear a scope
A low scope bolt handle - not the typical bend or forging
Cut and crown the barrel
Cut the receiver for the bolt handle
Drill and tap for scope bases - using a jig.
Polish and blue.
Or just forget it and trot on down to Walmart and save a few bucks.
I swear by Jupiter Optimus Maximus .... in the army of the consul Lucius Quinctius Cincinnatus and for 10 miles around it I will not steal anything worth more than a sestertius in any one day.
