Geissele MK4 ODG Fed Rail used for the FBI HRT rifles. Also includes an stripped Aero Precision upper with no forward assist. Has some light signs of use, but overall great condition. Comes with the barrel nut and wrench. I'm also selling some ODG furniture in another post if you want to pair them all together. $340 for just the handguard. Can meet anywhere along US-75 from McKinney/Anna down to Dallas.
