Palmetto State Armory used a screw they epoxy'd into the gas tube hole of the front sight base to hold the handguard cap.
Because it interfered with triangle handguards, I tried removing it and created a "would not screw back in" condition.
So I ordered a pistol gas tube and cut it down to provide a block to rotation at the handguard cap.
A longer gas tube would have been better because it would have been straight here.
No matter! Thag have hammer!
Now there's a stub of a gas tube to help hold the cap steady. There's a washer-like slip on fastener that I cannot recall the name of that would be perfect for holding the cap forward... As soon as I remember what they're called I will order some.
Update: Retaining washer!
Kinda neat looking in the cooling holes and seeing gastubisinterruptus.
Wile E Coyote school of gunsmithing for the win!
