[MOD] XYL KM9 Unicorn Blaster Overhaul! (With metal and 3-D printed upgrade parts)

In this video, we completely overhaul the XYL MK9 Unicorn, a foam dart blaster. I take you through the process of breaking down the blaster, giving it a sweet dye job, and adding an awesome upgrade kit from Black Raisins along with some 3-D printed parts. This blaster is now shooting upwards of 200 FPS and looks much more tactical. Check out the video to see how I did it and let me know what you think in the comments.

With the prime being tough at times, I found that was more caused by the barrel than the spring. The stock barrel included with the blaster has that middle section that is machined to be a little thinner (probably around 15mm) around where the priming block is. When you change the barrel to a fully 16mm od barrel, the priming block can get caught up on it. I'm not sure if anyone has designed a new priming block with a slightly wider hole, but it's worth looking into. You could swap back to the old barrel just to make sure that's the issue, but obviously that would knock your performance back down.

[@NaptownNerf]

Yeah, I talk about all this in the second video that will be coming out next week. Also, after shooting that video, I found out that they do make a 11 1/2 inch replacement barrel that is threaded now. I put the link in the description.

[@asliceofnerfpizza8549]

Oh cool. Nevermind then lol

[@frogsbutfrogs]

​@@NaptownNerf you could probably get a updated one if you email out of darts customer support for free

[@Bleenga]

Love it! That purple dye looks great

[@chaplainjinx]

That dye job came out looking great

[@darrenwalsh7866]

it amazases me now that 200 fps is kinda the norm now a couple of years ago 200 was a holy grail build shows u how quick stuff moves

[@Shadowsword12]

Awesome job on the dyeing. The Geese must like it cause they wanna know the fps reading too lol.

[@nerferx]

Heya Naptown. Thanks for the great video. It shows me that I dont need to spend the money on the metal parts to get 200fps+. Use 29cm of Swift barrel and a Kronos 18kg spring, and your there with worker bamboos and your choice of bcar. And its not a hard prime. The prime on the blaster does get easier once the priming blocks bearing wears into the barrel. The factory barrel has the thinner outer section so the bearing dont destroy the barrel. The factory barrel and a Bigshock spring gets it to 130 fps if you wanna use it for hvz. Its not a bad little blaster, and its great for cqb stuff.

[@CRNerf]

Wow. What an upgrade!!

[@LillyValentine252]

Try a 30cm barrel with the BlackRaisins 1.6 long spring and a 1”inch spacer. That set up for me is doing 230 on red workerHE’s 1.g

[@The_Mess85]

Yeah, I'm going to buy one, but I need to get it from Biu Blaster as Out of Darts can't ship it here to NZ ;-; It's also NZ$148 last I checked, but that's with GST and shipping, so not that bad. And daaaaaaaamn, that dye job looks bloody good, nice work!

[@NaptownNerf]

Thanks. It definitely turned out pretty darn well, especially for my first attempt.

[@Telefrog]

Looks great! I don't know if that rough of a prime is worth it, but I'd be curious to see how it fares after a day of game use. Good job!

[@NaptownNerf]

Stay tuned for next weeks video. Full testing done with multiple barrels and springs.

[@thehollowlingwin]

Just be be careful with the pusher o-rings on this kit tending to fall off...a lot under hard use

[@arenhansen625]

Do you find that the pusher no longer engages the slam fire mechanism causing it to not fire sometimes?

[@NaptownNerf]

I did have this problem a few times at first with the beefier spring and the long harrier barrel. But when I tested with their barrels, I didn't seem to have the issue. So I wasn't sure if this is a problem with the kit or just with this set up that wasn't really intended.

[@darrenwalsh7866]

nice sbr buid unicorn not my yhing but u made i look good and shoot right

[@nurnberg1561]

Unicorn MK9 gel blaster. 200 fps nylon for 48 dollars. Foam darts blaster are not for me

[@willco5431]
