I got a Daniel Defense LPK to put together a second lower and noticed they sent 2 buffer retaining springs, one slightly longer than the other, though they both have the same amount of coils. The entire lower is put together except the buffer retaining spring and plunger, and the rear takedown pin detent and spring. Given they have the same amount of coils, I am assuming either the shorter spring has been compressed and taken an initial set, or the longer spring has been stretched. Does anyone have a new buffer retaining spring they can measure to see what size it should be?
