How long can I use my existing weapons qualifications score for?
Annually, two years for promotion purposes, and no, newer qualifications override older ones.

Marksmanship Badges.
An award for previous marksmanship weapons qualification is revoked automatically
whenever an individual, upon completion of firing a record course for which the previous award was made, has not attained the same qualification. In the event a badge is authorized for firing a limited or sub-caliber course, it is automatically revoked if a record service course is subsequently fired. If the bar, which is revoked automatically, is the only one authorized to be worn on the respective basic qualification badge, the award of the badge likewise is revoked automatically. An award once revoked will not be reinstated.

We cannot simply 'rest on you laurels' when it comes to individual qualifications.
See if your NCO will send you out with another platoon or Company to improve your score, in the meantime get back to fundamentals, they really so solve 90% of the issues that come up.
