I have a Springfield and mine is a 1-7, but mine is a model 710 ARM. I restored mine back to its original glory after the assault weapons ban expired. I installed a US made piston, pistol grip, hammer, trigger, & sear. And then I installed the original folding stock, bipod, night sights, carry handle, and flash hider that actually came with the rifle when I bought it back in '91. Mine came with the thumbhole stock installed but I paid a few bucks extra to get the "accurizing kit" which included the original items (uninstalled). They sat in storage until it I was able to legally install them. I had to have a piece made that I attached to the stubs on the bottom of the gas block (where the original bipod mounts were ground off) to attach the biod. But it looks great and you cannot even notice that this work was done until you look very close.
These are great Galils. And now that they can legally be restored they are an awesome way to get ahold of an original IMI Galil. I paid $700 for mine brand new back in '91. I'm so glad I got it. I held onto it when at times I did not know why. Back in the dark years of the AW ban it seemed impossible that it would ever be legal to restore it to its original configuration.
