Even though I have been shooting fo a while, this is my first lever action. I bought it used from a reliable source, but I am having a few problems.

1.) My gun has extraction problems. Every 4-5 rounds, the lever doesn't want to open to extract the case. Once I force it open, the rest of the cycle works smoothly. The next 4-5 ronds are great, and then another jam. The ammo I have been shooting is really cheap (Monarch), and it seems like a stuck case type problem that I had in a Remington 700 a while back. Anyone have any experience with this type of problem in a Marlin?

2.)The guns sights were removed and lost along with the screws a long time before I bought it. What size screws are the front sight srews and the receiver scope mount screws on a Marlin 336?

3.) I am planning on machining my own peep sight for the receiver and front sight for the barrel. I am a competent machinist and it will be free for me to make it. Any recomendations?
