YHM Four Rail Free Float AR-15 Forearm Carbine Length (Overall length: 7.2 in - Weight 14.3 oz.) (YHM-9479) this one is called the solid model. I bought the Specter length one and used the barrel nut, jam nut and anti-rotation screws from the original one, so all the parts coming with this one are new and unused. The Forearm is in mint condition $75 Shipped or F2F (SOLD)
