The best video by far on this platform on how to build Roller Speargun. Appreciated much Sire

[@dustsnow666]

thank you !.

[@yasserbenahmed3273]

Thank you so much for the information

[@aronminguete6519]

Share lists of material used, please.

[@АлександрЯкубинский-т1б]

hello! Where did you buy this carbon tube?

[@intras9220]

Where can I find a list of materials you used in the video?

[@finnbismark]

Ali express has carbon fiber speargun barrels that look identical to what he has and he names the manufacturer of every other major item required so they should be easy to find

[@reybanalo803]

Thank you Sir for a clear illustration. I hope I can make it in my own spear gun.

[@neilhay2155]

Thanks for sharing, very well done and inforative. I like the inverted setup as you can power your shot to suit on the fly.

[@dustsnow666]

Cheers Neil, yeah nowadays I struggle to find scenarios where an Invert is not superior... hole hunting being one of them

[@ruanviviers8222]

Thank you for the vid. What is your barrel offset - 2.5mm, or 2.8mm?

[@dustsnow666]

2.6!!

[@Chris-ok9hr]

How do you get the dyneema through the inserts. I got one done but the next just keeps fraying and won’t enter the dang hole.

[@dustsnow666]

@@Chris-ok9hr can you ping me a picture? [e-mail]

[@karlovukman7586]

Great video...can you tell us where to buy carbon body?

[@MikeTheGuy33]

Looks like chinese barrel from AliExpress

[@nocrass]

Hello, it would have been nice to give us the lenght of the rubber in your case

[@dustsnow666]

200mm, 16mm, small ID. Natural Rubber. I use Sigal Sub or Epsealon

[@notpastranapastrana2403]

quick question, if you remove the handle, will that gun fit in the check in suitcase? i want to have an invert roller for travel but may not be possible..idk..thansk

[@dustsnow666]

Hi Mate, the defining factor for lenght is always the shaft, not the speargun. the shaft is always longer than the gun. so you need to buy a specialized shaft that can be split (Roffe Euro Traveler for example), look it up. taking off the handle and re-fitting too many times can damage the orrings, resulting in leaks, i would only do it for maintenance, ballasting or in special occasions safe hunting Ramsey

[@notpastranapastrana2403]

Thank you

[@keisenscalzo8382]

Can you make a video of putting a reel on it

[@dustsnow666]

I can post a video of the 110, which has a reel installed. I recommend the MVD free spooling reel for this handle. cheap and sturdy

[@StaunchIndustries]

very nice... wish i watched this 3 years ago...

[@Ahokieforlife]

What barrel exterior width and offset are you using here?

[@spearfishing2435]

Waiting for part 3 Nice job

[@dustsnow666]

Thank you! Sorry for the late response, We just came back from Madeira with some footage, but we have another trip to Rhodes in 3 weeks so I will put something together after that. Thanks for watching .

[@dustsnow666]

Just posted an accuracy test video of this Gun!
