Firearm rail system
First Claim
1. An attachment for a firearm having a barrel with a barrel nut mechanism located around an aft portion of said barrel, said attachment comprising:
- a) a supplemental mechanism adapted to be positioned proximate to said barrel;
b) an attachment mechanism secured to said supplemental mechanism having a first and second claw diametrically opposed to each other and positioned to be accepted by said barrel nut mechanism;
c) a barrel handguard completely surrounding a portion of said barrel and having,1) an upper portion permanently attached to said attachment mechanism, and,2) a lower portion swivelly connected to said attachment mechanism at a first end thereof and having a locking mechanism at an opposing second end, said locking mechanism selectively engaging said upper portion;
d) an attachment rail;
e) a rail mechanism secured to said upper portion of the barrel handguard and secureable to the attachment rail;
f) a side rail engaging said rail mechanism and the attachment rail; and
,g) a compression mechanism compressing said side rail against both said rail mechanism and the attachment rail.

Abstract
An attachment for a firearm having a barrel with a barrel nut mechanism located around an aft portion of said barrel. The attachment includes a shield or supplemental mechanism which is positioned close to the barrel. An attachment mechanism having a first and second claw diametrically opposed to each other, are positioned to be accepted by the barrel nut mechanism secured to the barrel. In the preferred embodiment, the attachment completely encircles the barrel using an upper portion and a lower portion which is swivelly connected to said attachment mechanism at a first end and a locking mechanism securable to the upper portion of the barrel handguard.
