I'm thinking about getting a new upper for my CAV-15. I'd like to get an A2 with full front sights, and a free floated bull barrel. Some of my concerns:
1) I'd like the rifle to be light in weight. It is actually for my wife so weight is important.
2) I'd like to be able to attach a harris bi-pod to the handguards to keep it "free floated".
3) I'd like to have it as accurate as possible but accuracy isn't the end-all. So here in lies the title of the thread. What are the accuracy potentials of the 16, 20, and 24 inch bull barrels? What are the weight differences between them?
Any advice as to options, manufacturers, etc.. would be appreciated. BTW I like the free floated handguards with the rails on all four sides by Fulton Armory. Are there any other similar hg's out there?
