I have decided that due to financial restraints to go from building an AR15 to getting a Yugo and the T-6 before the Democrats start telling me what I can and can't own. The only thing I don't like about the SKS is the barrel length. I am fond of the 16" barrel of the AR15. Can I have the barrel chopped by a gunsmith without FUBARING the cycling rate? I would like to have it shortened as much as feasable and put an aftermarket brake on. Any info would be greatly appreciated. Thanks

 I shortened one to 17" moved the ft sight block back to the gas block and put a A2 hider on it i did have failure to cycle issues with one batch or Wolf MC and sluggish cycling with everything else but functioned ! there is two ways around this #1 enlarge the gas port slightly #2 , I trimmed  the recoil spring and the op rod spring SLIGHTLY and now it functions fine with any ammo I use If you enlarge the gas port too much you cant put  that metal back without major work! if you trim Too much spring off  just go buy another as cheap as they are. Good luck!

The issue of short or sluggish stroking may be due to the distance from the muzzle to the gas port being too short. The same issue is had on the AR, especially the SBR'd ones. A general rule of thumb is 3" from gas port to the muzzle with no flash hider/compensator.
