Here's my Saiga-12
It's been stripped and sandblasted.The receiver, dust cover, barrel, and ladder rail protectors have been coated with Tungsten Cerakote while the bolt, trigger, trigger guard, safety lever and bolt hold open has been coated with graphite black Cerakote. Internal work includes polishing trigger and the bolt. The bolt has also been shaped to allow a full magazine to be inserted wiht the bolt closed.
It's a 4 port gun and the gas ports have been drilled t ensure they are uniform. The gas block as also had the hole enlarged a little to ensure the ports are not covered.
