Bigdog, your Saiga should be ready to go to the range stright out of the box. A few things to do fist.
1 Remove the top Cover by pushing on the rear spring, and lifting off the top cover.
2 Remove the bolt carrier and bolt, by pulling to the rear. Pay attention to what you are doing.
3 Clean barrel and chamber, to remove any grease or dirt.
4 Remove gas tub, and clean.
5 Put back together, and have fun at the range or pits.
Hope this helps.
