Not for the A2
I picked this single point sling because the pic showed it on a full size rifle. The problem is that I can not properly operate the charging handle with out loosening and moving it half wayish to the rear of the butstock. This is the most comfortable sling I have ever put on, no where near as rough on the neck as the stock sling is.
Good sling for some uses
It is a great product made with quality materials. If you are looking to attach it to the stock of your shotgun with the clip attachment I would say STOP and think about it. I bout it for my Knoxx Breachers Grip but even when fully cinched up my 18 in. barrel still hangs just below my ankle. Pretty much sucks with stairs.
If you are looking to buy for another usage go for it! It is a good sling that I would suggest.
