Need more info to try and place it in the lineage of M11s.

Does it have an Accu-Trigger?
Does is have an upper bolt release or a bolt release in front of the trigger guard?
If it has an upper bolt release if it was manufactured before 2013.
A lower bolt release would indicate that it has an Accu-Stock.

Twist rates on .223 Savages are normally 1:9 but some of the newer target models come in 1:7. I would doubt that you have one of those.
You can check the twist rate with a cleaning rod and a patch. Count the number of times the cleaning rod turns and divide the number of inches of barrel by the number of turns.
A 22 inch barrel should turn 2.44 time for a 1:9 twist or 3.14 times if it is a 1:7 twist.
