You might try putting the barrel in the freezer overnight and heating the gas block in the oven to make it go together easier.
There's so many different mfg of Ak parts, unless it was a matching number kit (even then) the gas block and front sight could be a tight tolerance, or one you can install with a soft mallet.

Best thing to do is watch lots of video's of AK builds, have the right tools, or find a COMPETENT smith to do the work.
