If you think the SIG 556 is heavy for a .223 rifle, the Galil is heavier.

Not really. The Galil's weight is a little more spread out than that of the 556, which has all of it's weight in the very front. I recently handled a 556, and it's weight distribution suprisingly reminded me of a Polish "RPK" knockoff that I had held sometime earlier in the year

FALs are nice, only shot a DSA but then again they dominate the market. Id like something more optics friendly though, since my vision sucks. Contacts shift a bit making precision shooting tough. I bet there are good FAL mounts, i just didn't see any on the gun i shot. Maybe a top rail would be nice.

The sig doesn't feel unbalanced to me weigth wise, i just hate the folding stocks (too short.) A collapsible stock version may fit well.

Not really, Galils have almost the opposite problem - a lot of the weight is more towards the rear. Especially with the stock folded (though of course, that's not how anyone shoots it).

It's not a bad rifle, but there is a good reason that the IDF ditched it and went AR.

Don't they make FAL's with rails?

They make anything with rails nowadays

Ok, I've held an M1A and it is way heavier than a basic AR-15.

What kind of AR are you talking about? One made of depleted Uranium (super heavy) with hardwood furniture? There is no way that a normal AR weighs more than a M1A

M1As are around 11-12 pounds empty, An M16A2 is a little under 9 with a loaded magazine. I don't think 9 is 12 hehehe.

They make rails with rails nowadays... :)
