5KU 7" Full Metal Outer Barrel for M4/M16 Series Airsoft AEGs - Black

"Very solid, fit great in cm16 raider L.

"Solid. It fits on every upper I've paired it with (g&g CM16, Krytac LVAO, g&p)

"This barrel is great and is the prefect length for a 185mm inner barrel. I did have to slightly modify my barrel nut to get it to fit.

"Feels great, albeit it wasn’t long enough while paired with my suppressor to stick out past my inner barrel. Calculating the numerical values put my inner barrel length at 14.3in, while the 7 inch barrel 7.5in suppressor at 14.5 inches. I vote 4 stars instead of 1 because the build quality is great and it fits snugly in my G&G cm16 gen 1 paired with my maxx me pro.

"Price is great but I gave it 3 stars because the 14mm negative threads are not the greatest. None of my flashiders, suppressors, or tracers fit good. You can thread them maybe once around and they get so tight that they won't go anymore. They all work fine on all my other guns outer barrels.

"passable, but deadly to the ears when you're trying to attach something to the threads. could do with a generous lube there.
