I will pick up three of those M1 carbine recievers tomorrow(one for me and the other two go to my work buddies) from a little armory bussiness here in my home town. They will be brand new Springfield receivers. The smitty told us to get a certain video that walks you through each step of assembly, and we will let him do the head spacing work and a few other things that were not qualified to do. I have never done anything like this before and could use any support out there thats available and willing. I have a few questions? 1) Who sells barrels and who should I buy from and what type ? 2) does any Company out their sell 'kit packages'? 3) am I getting in over my head or can a mechanically capable person get this project done with a little well focused enthusiasm ? 4) What type of tools should I be sure to have on hand before I get started? Thanks for any and every reply. I will need all the help I can get. Thanks. John
