KAPP's BM2K vertical adapter allows Bushmaster and Defiant users to get rid of their stock regulator and upgrade to one of their choice. KAPP's BM2K vertical adapters come in six high gloss finishes (chrome, black, red, green, blue, purple) and have a laser engraved "K". Adapters also include a KAPP sonic flow screw to connect it to the body and improve air flow to gun. Adapter is threaded to carry a pressure gauge in the front to properly adjust pressure.
The KAPP Vertical Adaptor is older, so while it may be available used and in a few cases new, it is not commonly available anymore.
Stock asa, older one so u can't put any aftermarket reg.
Dye Boomstick 14"
Cp grip reg
Kapp VA with 300 psi Dye gauge
Evil rail and ASA
68/3k PE tank
None so far
I got the older one with no milling
Well, i got a CP reg before i got the VA, so when someone is selling his used with no gauge, i took it. I installed a 300 psi Dye gauge so it works even better. It looks good with my bushy. All black and the length with the CP reg is perfect, it's almost the same with my trigger frame. I dunno what year is mine, but i guess it's the older one with no milling on it. U can even rotate it in any way u want so the reg can be on either side of the marker.
This thing works flawleesly, it does it's job. the looks are not fancy of course. But hey with this i can put any reg in.
This review is going to be more of a counterpoint between my first VA and the Kapp which I now own.Originally I had the Planet Eclipse VA and thought it would be fine but after a couple of Weeks of using it the threads stripped off of the adaptor. See the Eclipse design has a threaded nipple that attaches the adapter to the gun, while the Kapp uses a stainless steel ported screw to hold the adapter in place. I found that as I played the Eclipse would constantly work itself loose and after having to tighten it over and over again it finally just gave up and the threads stripped. Also the eclipse is really short and thin which is good if your going for max compactness but doesn't allow a screw port for gages. The Kapp adapter is almost 2x as long but is made with a guage port so you can keep track of your psi/velocity. Also because the attaching screw is separate from the body of the adapter you can position your guage and the logos how you like then tighten down the screw. The Eclipse being one piece meant that you had to take it however it would line up on your gun once you screwed it in.
All things considered I don't really see how you could make this product much better. It's a pretty simple piece that does it's job well and looks good doing it. True that it is on the long end of the spectrum but IMHO that is fine because it balances the overall height of the Bushmaster/Defiant series of markers and provides a good hand grip. I don't believe that anything can be perfect so I don't give 10's but this is definitely a good item.
