I have removed the forward scope mounting rail from my Scout and installed a standard handguard.
Then installed a Bassett scope mount.
I have tried to remove the handguard with the action out of the stock and the mount still on.
I found there is not enough clearance under the scope mount to raise the receiver end of the handguard high enough to clear the receiver and slide the guard back out of the front band.
I even tried it with a handguard with no clip on it, still could not get it out with the scope mount on.
The quick on/off of the Bassett mount allows the handguard to be removed without messing with the gas assembly.
What reason do you have for removing the handguard?
It can be left on the action when the action is removed from the stock.
Nothing under it that needs service or lube.
So.... you'll have to either remove the scope mount or slide the gas assembly forward.
Or, just leave it on the action.
