Your previous comments are what prompted this inquery. It seems to be a quirk specific to L42's as it seems the vast majority all "regular" No.4(T) rifles still have them.
I'm just curious how many stray from EMER proper spec.
From the previous page the totals just from the posts are (correct me if this doesn't add up- not much time to "cipher"):
With : 4
Without: 14
NOTE: Running totals will stay on Pg 1 entry #1 for now.
