FWIW, I recently converted my 20+ year old Savage 110FP Tactical in 3.08 Win to accept AICS pattern magazines. I had bought a Choate Tactical stock last year and sent it to CDI Precision Gun Works in Florida. They did the inletting on my stock and sent it back with a DBM style trigger guard assembly. All I had to do was cut the front bolt down to size (to clear the bolt) and now I am able to use 5 and 10 round AICS pattern magazines from Magpul without any issues (so far).
