KRISS VECTOR (BRRRT BRRRT) GO FAST FOR YOUR SMG (2 POSITION)
INSTALLATION INSTRUCTIONS AND VIDEO IN THE BLOG HERE ON THE WEBSITE.
Gen 1-3
45acp, 10mm, 40S&W, 9mm
THE GEN 1 TRIGGER IS MORE DIFFICULT TO GET THE BRRRT TO RUN CONSISTENTLY BUT RUNS.
GEN 1 KRISS VECTOR WILL NEED A UPGRADED FIRE CONTROL GROUP WHICH IS AVAILABLE FROM KRISS DIRECTLY. THEN THE GEN 1 CAN BRRT BRRRT AS WELL.

A simple drop in ART for the acclaimed speed demon, the Kriss Vector. This will make your Kriss Vector run how the designers wanted it to. It's an unruly beast of speed and firepower. This is a bump fore device and not a "full auto conversion". Learning the system and running it does take to finger control but ripps when ran properly. Our blog has a install direction on how to get this to run properly.

My part came in and have not got a chance to install it. Just to let everyone know that you only get 2 screws and 2 pieces of cylinder plastic pieces.

Didn’t work
I bought this and installed it as shown in the install video and it didn’t work. The trigger actually wouldn’t even fire when the buffer spring takedown pin was in. After no response from customer support after multiple days. Don’t waste your money. If I could give zero stars I would

Failed before first use
I paid a premium price for this product and received two small 3D-printed plastic components and a screw. During normal installation, one component cracked. The second became lodged inside my rifle’s fire control group, and while attempting to safely remove it, the part was lost entirely. The product never functioned even once. At this price point, this is unacceptable. The material choice is a major issue. The 3D-printed plastic is brittle and prone to cracking, chipping, and failure during installation. For what this product costs, billet aluminum would be a reasonable and appropriate material. Plastic components do not appear suitable for this application. Installation support is also lacking. No printed instructions were included, and there was no detailed installation guide available. Critical steps—such as polishing, correct roller orientation, and common installation errors—are not explained. A proper installation video is clearly necessary to prevent damage during installation. Visibility during installation is another concern. The small components are easy to lose if dropped or dislodged during installation or removal. Producing them in a more visible color would help reduce this risk. A component cracking or becoming lodged inside a fire control group raises serious reliability and safety concerns. This should not occur before the product is ever used. Overall, the product failed before it could be tested, did not function as advertised, and left me without a usable product despite paying full price. Unless significant changes are made to materials and installation support, I would not recommend this product and would hesitate to purchase from this company again.

I got the frt for my Gen2 9mm. At first I had problems but noticed they made a video. I followed the instruction from the blog and video. Still couldn't get it to run. I called and spoke to the folks at EP. Those folks are awesome and were able to get me running quick. Now my Kriss is my favorite range toy. Customer service is top notch.

Ability required
I have seen some reviews about the function of the BRRRT. I had some initial problems with getting the trigger to function as was able to get in contact with the fellas at EP. They were able to get me some insight on how to get my Kriss working great. I personally found that the internals needed polishing as I had missed from not looking at the blog which caused my first part to fail. My 3rd Gen 10mm runs like crazy now. What a blast at the range today. My advice would be to reach out to EP if you have any problems or maybe lack the knowledge of how the gun works. The Kriss is a funky gun but those guys seem to have found a way to make them be the ultimate range runner.

Questions and Answers
Q:
In one of the reviews, the person had a Vector Gen 2 9mm & installed it & at first it would not run but then he contacted your customer service and you helped him get it to work. What did you tell him to make it run correctly? Thinking about getting the exact same set up. Thanks in advance.
Asked by:
JP
- 1/14/2026
A:
There are a few different things we go over upon a customer call in. It varies just like the guns do. Fitment, polishing, etc and we make sure to have them go over to the blog to assure they have made the appropriate adjustments that are needed.

Q:
Hey I talked with Chris about my kriss and I polished the holes and around the bolt head and had to end up filling a little off because the bolt screw was hitting the plastic on the bottom. I got it all together and I put one round in and it shot fine. I put 2 rds in and shot both so then I put a full mag in it and it shot about half of it like it should very fast! And then started single shooting again and half of the plastic pc fell out of the bottom of the gun. It worked and then broke in half. What would cause that and could the part be made from hard nylon or with aluminum, brass softer metal? The Ar trigger worked great and will be buying more of them!!

Brian

Hello Brian, reach out to Chris again and I am sure he can get you going again. Thanks again and have a great day

Q:
My gen 2 won’t fire unless the one buffer spring take down pin is out. And with it out the gun obviously doesn’t work. why might this be.
Asked by:
Zachary James Miller
- 12/2/2025
A:
I found that my safety spring came out of place when I installed the parts. I called in and spoke to one of the guys at EP and they walked me through it. Be sure to polish all the parts they describe and to lubricate well including the frt roller. The first couple of mags the trigger was stiff but once broken in it screams now.
