Do not attempt to disassemble or adjust any of the recoil mechanisms.
The internal springs have a 40,000+ round life expectancy and should not
require replacement.
As part of regular firearm maintenance apply a small amount of "plastic
safe" lubricant (not WD-40) to metal and moving surfaces. Very little lubrication
is required so use sparingly (1-2 drops). Do not apply lubricants to
other areas of the stock. Stocks subjected to extremes in humidity, sand,
dust, or temperature should be cleaned regularly (Use compressed air if
available) and lubricated with the appropriate lubricants for the environment.
If the stock is submersed in saltwater, it should be thoroughly
rinsed in clean water and dried thoroughly (Use compressed air if available).
The exterior of the stock may be wiped clean with a cloth and
cleaning products safe for plastics.
