Great looking nerf gun

I bought this hardware kit with the 110, 130 and 195 FPS springs. The low springs are great for low risk shooting and the 195 is a power house that scares anyone that has a nerf dart whiz by them at mach chicken.

Awesome Nerf Blaster

This was the first nerf blaster I have made, and It was so much fun to print, assemble, and use! I would recommend for everyone (who are strong enough to load this thing) that wants a fun, rewarding build.

Absolutely perfect and cheap!

This is one of the most fun ive had with a hardware kit. Its simple, step by step guide and it took me only an hour or two to put together. Would definitely recommend!

MADE IN UK: CALIBURN 4

Jessica/Diego were a delight to deal with.
Helped and guided me to what I needed without a fuss.

Dilvery was under 2 weeks which is incredible when you think of distance/logistics.

Items well packed with a tick list of everything in side.

I would highly recommend and will be coming back for more.

Nice kit, one minor issue that should go away on breaking it in

Everything went together swimmingly, the only two issues I encountered with the build that weren't self-inflicted via my printers were that the paracord was tough to wrap around the posts according to the video assembly, and that there's a minor issue with the plunger spring "catching" early during priming in the gap between the two acrylic tubes that isn't well filled with the print of the Stock piece. I expect that last one to go away as the blaster "breaks in", as it's being caused by the spring buckling against the chamber.

Great Hardware Kit

The hardware kit was excellently put together, with extras of several of the most used components. The packing was great, everything arrived in pristine condition, and it was obvious that care and intention was taken into the delivery of my order. I will definitely be ordering from Out of Darts again in the future!

Excellent Kit

Everything one needs to build a Caliburn C4, minus the printed parts. Well packaged and organized. Very nice, if not excellent, quality of the fabricated parts.

Parts are great, oil busted during shipping, CaptainSlug assembly website was down...

To start, the actual hardware kit is great. Everything in the right sizes and quantity. My oil did not arrive in the bottle, but all over everything in that bag. When trying to view / download the assembly instructions, Captain slugs site was down, wayback machine to the rescue. I think sites who sell hardware kits with permission should also get permission to host a mirrored copy on their own site.

Great kit, super easy build, absolutely love it!

This was my first 3d printed blaster that required hardware and it was a great build! The kit came with everything i needed and extra. 100% recommend!

Super Fun

I got mine with the 18 inch barrel and k26 spring. It shoots so hard that if I hit something at too close a range, the impact will tear off the tip of the dart! Super fun to put together and my tolerances were PERFECT. I printed all the black parts with Overature PLA Pro, white is Overature PETG and the orange parts are Prusament Orange PETG. I wanted it to be sturdy so I made everything between 50-70% infill with the smaller parts at 100%. The plunger is printed in GiantArm PETG. I also added an extended butt stock. After reading about the build, I added a small washer to help keep the little grommet on the plunger in place.

Made (most of) my Talon Claw dreams come true!

Excellent kit with excellent support. I appreciated the dupes of some of the hardware to save me from my inevitable clumsiness. Only reason I didn't give it 5 stars is that one of the bars wasn't drilled through correctly, which prevented me from a full assembly - but it's put together enough to work!

Squirrels of the neighborhood.. beware..

Pretty good

At first I thought there were a bunch of issues, but they helped me out a ton over email and got everything resolved. Now the blaster runs great, I'm happy. Everything was the right size, nothing seemed to need much cleanup. The screws kinda suck, they strip and shear easily, but not worth docking a star. Hope that's resolved soon. Fast shipping and quick responses as always.

First Blaster Build

I’m new to 3D printing and bought this kit to build my first blaster. Everything worked perfectly, the build guide was helpful, and there was spare hardware instead of the infamous 1 **** short!

Works Great

All the necessary pieces are there, with some spares.

Wonderful

First nerf gun that I have ever assembled and I could not be happier! I was able to fully assemble it in a day. It would be nice if it included enough screws for a shroud but either way it still had some spare parts for other things so all is well.

Thank you for having what it takes to make the coolest blaster

Arrived via international shipping very fast (then got stuck with royal mail definitely not OODs fault) but unfortunately came with an item swapped. I emailed and they had started a new order to send me the replacement item before I had even had a chance to send them a photo of my packing slip and incorrect item. 5/5 customer service all day long, I've always thought it's more important how people deal with you when it goes wrong rather than when it goes right, and Out of darts excels at both

Super fun kit and easy to put together

My kids and neighborhood have enjoyed shooting the caliber. I ordered multiple springs and it has been fun experimenting with different strengths to see how the dart fires. I would love to get more but now I need to work on convincing my wife!
