I'm building an AR pistol, and have decided on the 10.5" barrel.
As a pistol, I know the 10.5" barrel is ok per state and federal laws. The reason I'm building this as a pistol first is the pistol-->rifle--->pistol configuration change.
Anyway, to save a bit of coin, I'm thinking of buying the one upper with 10.5" barrel, and a 5.5" muzzle device instead of a second 16" barrel or barreled upper.
So here is the question: Does the 5.5" muzzle device need to be permanently attached (pinned and welded) to the 10.5" barrel when in it's rifle configuration?
If not, then a simple stock and muzzle device change to convert back to a pistol is cheaper than swapping out the barrel, or the entire upper.
If it does need to be permanently attached, then I'm back to buying either a separate barrel, or another upper.
