Hi guys before I get started I want to mention all the mods are in compliance with federal and state law if you are interested in doing this congersion and barrel mod you might want to make sure it is legal in your State to do I have an SKS that was given to me many years ago that had a folding stock I hate that stock so I decided to look around for other tactical stocks and I found the Tapco Intrafuse stock that I really liked so I ordered one (still waiting for the stock to arrive) since I am waiting on the stock I thought I would go ahead and do the barrel mod. The model I have has the 20.5" barrel I have shortened it to 18.5" I also removed the sight/bayonet lug and cut off the bayonet lug from the sight I also made a water pipe muzzle break that is very easy to make. the barrel , sight and muzzle break mod was done using basic hand tools and a dremmel tool. if you have some basic metal working skills and the tools anyone should be able to do the mods. here is the rifle before pic note the barrel length and bayonet lug here is the sight minus the lug the pins have to be punched out then the bayonet lug can be hammered off. sit the barrel on a block of hardwood and drive it to the end of the barrel once it starts moving it will be easier to knock off. once the sight/lug is off the barrel cut off the sight dremmel cut off wheel or with a side grinder cut off wheel, band saw or whatever you have then use a small dremmel drum sander to dress it up. I measured the barrel at 18.5" then used a tube cutter to etch a good straight deep line to use as a guide to follow with the cut off wheel Do not use a tube cutter to completley cut through the barrel because it will put a big lip on the inside of the barrel and can possibly dammage the barrel this is one of the best crowning tools and really cheap! I use the ball to crown the barrel set on high speed and chamfer it about 1/16" across the chamfer. the ball makes a slight concave chamfer. works really good. cut off the tube from the lug and save it because it will be used as a bushing for the water pipe muzzle break. I will continue this in the next post.
