JP Silent Captured Spring Weight?

[DRandi]

Put some superlube synthetic grease on your spring and buffer for sproing.
Works great,non-toxic and rated from -50 to 450 degrees.
Clear and reduces wear up to 4 times over other grease.
One of the best lubes I've tried.
14 bucks for a 400 gram tub on E-bay.
Enough to last a long time.

If your rifle is used for recreational use then this is fine, anything else avoid doing this. Was told by a big name manufacture, (think it was JP or Rock River) who the name escapes me right now that it adds a potential malfunction point if your must depend on your weapon. It will collect debris if you are in a dust enviorment. It will also plug the drain holes in your buffer tube.
