A lot of pictures I can see about the N°4, show the rifle equipped with a 1907.
But I also read that a Bren sling could be use. I'm using my Lee n°4 with a 1907 since a few weeks and my grouping at 200m is improving drastically.
A Bren sling is a web sling, with no loop in which you can fit your arm. How can it be better than a 1907?
Is there anybody who gets pictures showing how to use the Bren sling with a n°4 MkI?
Thanks
