So, my son has an old Glenfield 75 that he got from my dad. First, let me say that I'm a complete novice when it comes to firearms, but I'm open to learning. It wasn't firing correctly, so we broke it down to see if there was anything obviously wrong with it. As I was working with it, the lower receiver (think that's what it's called) separated. It's the part that's sandwiched between two steel pieces. So, now I have a handful of pieces and no clue where to start on putting this back together. Is this something that a novice can learn or am I better off taking it to a shop to have them reassemble it for me? I would like to do it myself unless you all say it's not something a newbie should take on and I'm asking for more headaches than I want. If you all recommend giving it a shot and can point me to anything that would help me out (video, schematics, etc.), I would greatly appreciate it. Thanks.
