You have an M1 Carbine rifle, but it's gutted... how do you put it back together? This weapons video will show you how to assemble the M1 Carbine rifle, which is a lightweight semi-automatic carbine that was used by the military in the 50's and 60's.
First, insert the bolt into the receiver and insert the operating slide. Next, insert the guide rod into the guide spring, and the guide spring assembly into the receiver face. Install the trigger group onto the bottom receiver and put the pin in. Now the action is assembled, so perform a quick functions check before install the action in the M1 stock, then put the upper handguard on. Now you have a fully assembled M1 Carbine firearm, free to shoot whatever.
