Here's the amount (by volume) of grease required when assembling various SRG units:
1:1 Compact...1.2 oz total (0.3 oz @ 4 positions 90deg apart)
1:1 Standard...3.2 oz total (0.8 oz @ 4 positions 90deg apart)

FAS Compact
Before initial use, a compact FAS should be filled with 0.35 oz. (by volume) of grease.
Additional greasing is a little subjective and is dependent on how the FAS is being used.
Continuous & Heavy Duty use: add 0.1 oz. (by volume) every 1½ months
Intermittent & Light Duty use: add 0.1 oz. (by volume) every 3 months
Minimum use: add 0.1 oz. (by volume) every 6 months
