well made sillybutts
This was my second ever blaster build. I printed the parts on my Elegoo Neptune 4 max out of PLA. The design is good and the parts fit together beautifully. The hardware kit had everything needed, and the build guide video was easy to follow. Having no hang ups from missing bits made the project easy and fun. The Out of Darts team shipped me the hardware kit faster than I could print the parts, even with a large fast 3d printer. The blaster is lots of fun. It seems very powerful and accurate to me, although I am new to high performance dart blasters, as I have only played with my sons basic nerf guns before. I'm very happy with it, and I had a blast building it.
This is my second kit from OOD and Sillybutts, and like the Alchemist, this was an absolute blast to build! Love the design and as always the kit was perfect. Thank you OOD and Sillybutts!!!
Constructing the blaster was a great time and it performs excellently. Couldn’t be happier, and I’m already planning to build more using these kits.

Kit arrived in a good amount of time, with everything non 3D printed that is needed and some extras. Video for assembly was easy to follow along with, everything went together really well well. Will likely be buying more hardware kits in the future.
Sillybutts is awesome. His designs are well thought out for assembly. The hardware kit is great and the assembly guide is helpful.
Design is amazing! Assembly was a breeze. This is the gun that people seem to have the most fun shooting for sure. Highly recommend.
I purchased a batch of four kits to build SLABs for my groomsmen. The kits are well organized and the video from out of darts is a great resource in assembly. Be a little careful if you use your own 3D printed parts as I did - because there can be some minor differences with how things look and go together. My shipment had a minor error with the wrong hex nuts being included, but support was able to correct the issue and ship out some replacement pieces very quickly without any hassle - they did a fantastic job!
The instructions to build this were very straight forward and very well documented. This blaster is so fun to play with. Had 0 issues with the hardware and the 788 spring gave me the exact FPS listed.
I was able to print and build and awesome SLAB from this kit! Everything I needed outside of the printed stuff was included and made getting the SLAB built super easy! Thanks for an awesome build kit!
I recently bought a 3d printer and had been on the lookout for a project my son and I could work on together. When I found this, he got super excited so we bought it.
First off, the STL files for this are some of the best prints I've ever made. Every part felt like it could have been off the store shelf. The assembly process was incredibly straight forward. The only issues I had was a tiny bit of filing to get a couple items to slide a bit better.
Once together, my son took the first shots and he loved it! He have a bunch of Nerf blasters, but with this he feels like he leveled up.
I can't recommend this kit high enough!
This is my first print on my Bambu Lab P1S (after a Benchy) and it came out perfect! The hardware kit has lots of extra parts and it's very easy to assemble. I flipped the side covers upside down on my textured plate and it adds a nice finish.
I have built a SLAB blaster using this hardware kit and plastic details 3D printed at home together with my son. It was a lot of fun. The kit is reasonable priced, contains everything needed and each item in the kit is high quality one.
An awesome blaster that is kid friendly. I made this for my 9 years old son, very easy for him to prime, and while not the hardest hitting, it is the one blaster that he has the most fun playing with. This is the one blaster that prove its not always about the fps, its the fun that matter. Kit included everything needed and instructions were very easy to follow. One suggestion I would have is a set of written instruction to go along with the video one, I always find myself working better with written instruction then video.
I am not a "modder" and had never even heard of a Nerf gun before seeing a video online of the OOD team doing a product review. Your products made it all too easy to enjoy the next few weekends putting together 2 blasters (SLAB and Lynx) with the hardware and parts from your shop, including some heavy tip darts and a Talon magazine. Great work for making these sorts of products and hobbies easy to access and understand for all users. I cant say I'll be firing the blasters at anyone or anything, but printing and building these has been great fun, and I'll likely be back for more in the future.
The SLAB was my first dart gun 3D printed and it turned out great. Everything I needed was included in the hardware kit and the assembly video made it a breeze to complete. I appreciated the addition of extra screws and o-rings as I did manage to drop a couple screws along the way! Overall, I'm very pleased with how my blaster turned out and can't wait for my next build.
This kit was a ton of fun to build. I printed all the parts at home, super easy and everything went together pretty quick. There was a little confusion on my part because the video doesn't quite line up with V4 and some of the standard mods like the muzzle break. But besides that its an amazing design with great action and power ( I used the 180FPS spring, GO BIG!)
The kit came quickly with everything I needed to assemble my SLAB. It came with a few extra screws and orings for optional parts and spares. I have zero issues with the drilled bars. Seem to be made to spec as all the blaster I have made with Out of Darts hardware have gone together easily. The printed part/s included with the kit are of excellent quality, I would have a hard time bettering them with my equipment. My only recommendation would be to add a option to included printed part or hardware needed in that part. Taking the large headsets out of the included parts is a hassle if your not sure best way about it.
Everything was there to put the SLAB together. I also followed Luke in assembling the blaster, I had no issues with his tut. Thanks for answering all my question quickly .
If you have a 3d printer you should get this kit! Even if you don't have a printer, get the 3d printed parts + hardware kit and put it together! With Luke's video, assembly is very easy and fun! And you save some money that way! I printed the parts and grabbed the hardware kit and I had a great time putting it together! Planking with it is a blast! I got the highest powered spring which is what I recommend because the prime action is still very smooth and also want to avoid chance of squibs when using the silly scar! Very high purchase recommendation, I'll probably pick another up soon myself!
