I remember seeing a Swiss Arms chart that shows the models and the various gas valve holes sizes, but I can't find it now. Would someone please provide me a link?

Here's my second SigSauer imported 553, set up on a virgin steel lower with SB brace with trimmed SB tube and SwissArms M4 adapter. The suppressor is a direct thread Sig SRD556 and I'm running a four position gas regulator set to "0.9" for suppressed duty. Ammo is Lake City XM193 (full power 5.56). Should note that the diopters with an Aimpoint mounted on a B&T rail is sub-optimal. Very busy sight picture....I think I'll move the rail to another gun and Aimpoint as well.
The heat of several mags through the gun definitely gave the can a nice new finish.

I believe in peace, love and extremely violent weapons systems... just in case that whole peace-and-love thing doesn't work out.
I wonder how much a sig 550 upper with nonmatching lower and bcg would go for?
