Nastiest sig rifle on the planet

[Dustbuster]

After 1000 plus rounds of circus ammo,w no cleaning, except for the rifle being clean before starting.....

It's a gen 2 sig 556R rifle 7.62x39 dirty

We cleaned it using IGG stiletto bath, brushes and patches. Nasty nasty nasty.

Hah same system. They've changed it for the xi series.

Was it still functioning well? Was it being lubed but not cleaned?

I'm surprised it got that dirty after only 1000 rounds.  "Ol' Dirty" looks better than that after 16,000 rounds.

It was getting more difficult to cycle it after changing magazines. all of the components stayed moist.the buildup was absolutely disgusting.we intentionally ran it without cleaning it or adding any additional lubrication,it did really well.
The gas valve got really boogered up and was almost impossible to get apart to clean, but after some persuasion it fared fairly well and was properly cleaned. Edited October 16, 2014 by Dustbuster
