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

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.

Love it! That purple dye looks great

That dye job came out looking great

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

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.

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

Wow. What an upgrade!!

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!

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

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!

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

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

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

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

Cool mod but kinda defeats the purpose of the Unicorn 🤔
