Zach here. Check the vid below to see a run down on my “go-to” gun, my MK18 Mod 1. Included below will be links to products that I added to this rifle over time to increase the reliability, performance and feel of my airsoft gun to get out of it exactly what I wanted.

For those curious, the batteries I use are 11.1v lithium polymer batteries of varying MAH ratings. The battery fits inside the buffer tube with the rear wiring and connector all in place. The base external build for this gun was a Cybergun Licensed King Arms Colt M4A1.

Spray Painting:

It gets asked often, but unfortunately, there is not much to tell. Painting this gun was certainly a task and I took time and effort to do so. I used stencils that I purchased online in the Kryptek pattern and purchased multiple types of paint. Ideally, I wanted paint that would last and make a decent seal with the metals and polymers of the build.

I purchased Rustoleum and Krylon camo paints in various shades of green, tan, and finally a flat black. To achieve some of the deeper browns similar to a flat dark earth, I purchased a vehicle paint called Aervoe which takes 24 hours to set. I do not recommend using it as you can find a decent Dark Earth/deep brown made by Rustoleum if you look hard enough.

My base paint before applying the stencil was a light, earth tan in a yellowish sand color. This was to be the brightest color, so I applied it first before going over the rest of the gun with consecutively darker colors. After applying the stencil to the sealed sand color paint, I applied a light coating of both a forest green and a light green from the Krylon and Rustoleum camo lines of paint. After the greens had dried, I used a dental pick to remove the stencils in some places but not all. With most of the stencil gone, I applied the dark earth paint over top of everything in light strokes to create a thin layer of brown over the tans and greens. Finally, I removed the remaining pieces of stencil still on the painted gun. With every stencil piece removed, I held a can of flat black paint far enough away from the gun to apply a faint dusting of scattered black to darken to overall tone of the rifle and remove some of the shine.

Other attachments were outside purchase or from Violent Little Machine Shop, which… I love those dudes and what they put out. But, I am also a patch whore.
