I recently purchased a used accuracy international mkiii that I’d like to get a picatinnny rail for the bottom of so I can run my LRA bipods. I found The anarchy outdoors spigot mount adapter that’s listed to work but I’m awaiting verification of that. The video on their site shows the at model which is a little different. The one in the video has 2 roll pins and threaded flush cups. Mine has one roll pin and I’m guessing what’s a clip in style sling mount. Not sure how this comes out. Also what’s the mounting system on the bottom the this model? It has one large circle cutout about 3/4” diameter with a slot about 4” long. Do they make an adapter to go in this slot? I’m open to suggestions. I don’t want to use the post style mount as I don’t like the slop. I’m spoiled with the LRA bipods mounted via picatinny rail. I’ll have a machine shop make an adapter if I have to. Thanks.
