Johnny's handguards are for a Sudanese or Guatemalan AR10. Carlson says he has a Portuguese lower. The earlier (Sudan/Guat) uppers will not work on a Portuguese lower. Therefore the handguard is useless to Carlson. The handguard system Carlson needs is a 4-piece assembly with heat shields and bakelite halves.

Still looking. Not even a nibble. Someone must have a Dutch AR10 barrel extension.

Except the set on gunbroker is "retro". Lately, that code word means reproduction. Specifically, its an M16A1 set that had been painted green.

Still looking.

Do you have a loose barrel extension or a shot out barrel from a Dutch AR10? I do not care what variant it is from. (Sudanese...Portuguese....whatever)

wood stock -$500 fiberglas replacement stock $0 original polycarbonate stock +$500 The polycarbonate stocks were very smooth and unpainted but were prone to cracking. Well, most original stocks actually shattered. Top is polycarbonate, bottom is a fiberglas replacement installed while the rifle was in service. Note the replacement stock uses wood screws to attach the sling holder.

You are very lucky to have a Sudanese AR10 blank fire adapter and a Sudanese grenade sight. The Porto BFA's are a dime a dozen and the Porto grenade sites can be had at a price.
