Any advantage to either? For a Rom. kit build. Also, can someone explain headspace, and how you do it with live round. These may be basic questions, but still getting info together and some things don't make sense. TIA

Go with the 1.0, it'll make your life much easier.  It's plenty sturdy enough.

I use a no-go gauge and a live round to check headspace.  Strip your bolt of the extracter (and firing pin) and put it back in the carrier.  Put the live round in the clean chamber and press the carrier forward by hand and watch the bolt fully rotate into battery.  Then do the same with the no-go guage, but this time the bolt should not fully engage.  If it passes those tests, you're good to go.

I'm not crazy about the idea of doing any testing with a live round.
Splurge, spend the $26 and get a go guage, to go with your no-go.

I don't blame you.  If you're not comfortable then by all means spend the extra money.  Since the firing pin, extractor, and FCG are not there, I figure it's about as safe as a no-go gauge...  I point in a safe direction, check for lockup, pull it out, and I'm done.  If you want to be really safe, I guess check with the no-go gauge first.  And even safer is don't use a live round.

If you are having someone else build it, 1.6. If you are doing it yourself, 1.0

I myself am going with the 1.6 because someone elese is building mine. (Partially)

I've got one of each.  With the 1.6mm receivers, you'll have to mill down the sides of your front and rear trunions by .60mm on each side.  Otherwise they won't fit in the receiver.

On a 1.6 you have to mill .60 on each side of the trunions.

I think you're correct.  Editing my mistake from above!

Go with the 1 mm. It is correct for the rifle and saves the problems of fitting parts as stated above.  If you are having someone else do the build they will probably charge you $25.00-$50.00 more for the fitting/milling mentioned above.
