This was an immediate take off from the rifle when new, no marks on it that I can see, comes with all attaching hardware (mounts to stripper clip guide, scope mount, forearm clip groove and clamps around op-rod guide)
I'm asking SOLD -SOLD-SOLD!!!. [email protected]
I'd also be interested in the following trades; A Glock 34 upper (slide/barrel), a pair of CM! 25 rd M1A mags, older Puma knives.
The standard rail ends right before the receiver, while the extended one shown here, extends all the way over the ejection port to the rear. The extended Cluster rail provides more mounting options for optics.
The Cluster rail has two major components, the upper rail/handguard, and the lower handguard. The lower handguard attaches and detaches in a couple of seconds with one hand by pulling back on two spring loaded catches on each side of the lower handguard and swinging it down. At the front of the lower handguard are two hooks which interface with pins at the front of the top rail. The side rails are part of the upper rail, so it the Cluster can be used without the lower handguard. The Cluster is made of aluminum and well vented. The rails are riveted onto the handguards. Threaded inserts at the 4:30 and 7:30 positions on the lower handguard are for attaching rails at those angles.
The standard upper Cluster handguard attaches to the barreled receiver at three points - the op rod guide, the rear of the barrel and the left side of the receiver. A U-shaped bracket is installed around the op rod guide, which is tightened to the upper handguard. At the rear of the barrel, a clamping mechanism secures the handguard to the upper handguard clip grooves on the barrel. A bolt secures the rear of the handguard to the side of the receiver using the threaded hole in the receiver used for attaching scope mounts. The extended top rail has a forth attach point. The stripper clip guide on top of the receiver is removed, and replaced with a rail attachment block. This is done by knocking out the roll pin and sliding the guide out of the dovetail, and replacing it with the new block. The top rail interfaces with this block with two screws. One screw has scallops on its head to prevent it from loosening, as it 'overlaps' the second screw. Quite ingenious. A channel runs the length of the center of the top rail so that the iron sights can be used. As mentioned earlier, the Cluster rail is a Springfield Armory-only offering.
