ETA: I got the barrel torqued on, easiest step so far. I got everything cleaned for headspacing, but want to make sure I have this right before I order a new LS. Started with a .266 Bolt closed on both guages. Moved to a .268, closes with easy pressure on the go, doesn't close at all on no-go. So .268 is the LS I need right? I remember someone saying something about setback? How does that play in. This is the first rifle I've ever headspaced a rifle, don't want to screw it up and blow my head off. I also screwed on the gas tube nut, but had a hell of a time getting it to thread through the carry handle. It screws all the way in without the handle, and pivots freely in the handle outside of the upper. I finally got it all the way tightened down, but now I can't move the carry handle. Any suggestions?
And how does the gas system work on these? What position does the gas piston plug need to be in? What setting should the adjustment knob be on? Is it trial and error until the rifle cycles properly?
Got my receiver yesterday, hand timed perfectly. Misread the Wecsog website though, needed a 1 1/16" wrench and not an 11/16". Have to wait til I can go back to Sears to get the right one. Tried fitting some parts just to play. It was really hard to fit the upper to the lower. I needed to tap it with a mallet to get it to latch onto the lower, then had to use the mallet to tap the release to get it back off. Normal? Should I even mess with it or leave it as a tight fit between the two?
