Ghost 300 BO Upper OD Green, Awesome Upper


Got the OD Ghost 300 BO Upper & it’s a solid fit on my Aero Lower. Fits tighter than my Wylde 223 Upper. The barrel is a beautiful HBar. Looks very nice with my Mag Pul OD Green furniture. I thought the Upper was gonna be darker but it’s a perfect match. Can’t wait to go zero it to the 4-14 & smoke some Hogs & Dogs

The Ghost 16” OD Green 300BO Upper


Picked up the Ghost Firearms OD Green 300 Upper at store. Beautiful Cerakote upper & fits very snug to my AP lower. She has a very nice & clean Heavy Barrel. Overall- impressive.. I Took her out & zeroed my PA 4-14 in a few shots & was then shooting sub moa groups at 100y. Cycled perfect with zero malfunctions. Shooting Remington 120g HP’s -white/ green box from Academy, OTFB I believe. She’s Perfect, IMO. Also matches my Mag Pul lower OD Green furniture perfectly. Highly Recommend buying 1 & you’ll have a 2 in 1 rifle if you already have a 223/556, so to speak.
