before you make the plunge into a 112 action, you need to know exactly what you are getting and what you can and cannot do with it. There are three different 112 actions as well as the material used in it. Sharp Shooter Supply has the drawings on line to determine which one you have.
* SSS sells a good trigger assembly for the 112, and it's easy to install. I used the Rifle Basix, and it works very well.
* Looking at the action, is it parkerized or blued? Single shot? (probably not due to the 7mm configuration) If it's Parkerized it will need truing for sure, and maybe so if it's a blued action.
* they sell after market bolt heads for the action, and this allows you to chamber it for just about any common cartridge. The action really benifits from a speedlock kit
** now the downside. The action is fairly heavy, and will flex a little. Scope mounts are a hassel, and plan on using a longer scope. I recommend using a rail mount that's dowl pinned to the reciever top (really stiffens things up). Also check the threaded holes on the reciever to see that they match up with your mounts (there was an issue with very old actions). I like the Farrell bases
