An OEM Rem 700 s/a or l/a ADL mag spring has 2 apparent/obvious differences than a BDL spring.
1.The ADL spring lower leg's "TOE" is curled up as not to effect inlet.
2. The ADL spring upper leg has an extrusion/DIMPLE to lock into the formed sheet metal followers folded legs to secure the spring.
A BDL spring does NOT have either of the 2 above additions.
Spread the upper & lower legs of the mag spring to represent a capitol "W" as compared to the pigeon toed configuration out of the box......feeding/cycling will improve.
