I have an FAL mutt, it is a century receiver with an Isralei lower and Austrian front end. I was wanting to go all Isralei on the gun with a heavy barrel, the gun as it sits now has a Styer barrel. I was wondering if the Israeli heavy barrels are as good as the Styer ones? Would it be worth it to swap the front ends or leave the Styer barrel and just change the furniture? The Styer barrel is not a heavy one.
