Yes, it was not allowed. And the reverse was true too; the SLR ones were not supposed to be used on the LMG except emergency use on active service only, 'owing to the stoppages and damage to the weapon which will occur'. Though I've seen that done as well, when somebody forgot to bring the right ones on a weekend exercise.
