I have been looking everywhere for the last few months for a AAC-SD and during my search I found a interesting rifle that I never even knew existed! It's a Savage 10PC but it has a 5/8" x 24 threaded barrel just like the AAC-SD. The 20" barrel is also fluted and includes 5r rifling with a 1:11.25 twist. This rifle also includes the Savage accustock and accutrigger. I looked all over the internet for a pic of it and finally found some pics on gunbroker Savage 10PC threaded barrel. I did not buy this rifle from gunbroker and have no clue who the seller is I just wanted to show everyone this neat rifle I found. I did however go to my local fun shop who found one and put it on layaway for me!!!
