The best solution I’ve found to not having a pinned front fixed sight tower/gas block is a sight held on by threaded allen screws. I used one of these with a 22 LR CMMG barrel to give the classic M-4 look. Having a gas tube assist in alignment. I used Loctite on the gas block/front sight on the barrel and screws. It has held very well for over 10 years.
If you want the retro M-16 A-1 look you might consider this.
