Well I decided to add a sling to my newly acquired, new to me 1100. It was one of those late night, been sitting in from of the pc bored kinda moments so I dug out the dremel and went to work.
The forearm QD is from IWC impactweaponcomponents.com
which I robbed from one of my Troy Ext. rails. It just so happened to have the perfect curvature to fit on the fore grip. The retaining bracket on the backside had to be recessed slightly to clear some moving parts.
The QD on the butt stock is also from IWC but is for a Magpul MOE rail. The backside of this socket is flat which worked out great for the butt stock.
All in all it turned out quite nice I think. The new flush version would have been better for the rear socket but, you know how it is... I didn't want to wait. I did order a couple to replace the ones I robbed off of the ARs though.
