Picture of BLOCKHEAD: Precision Crossbow

Here it is, the block-bowed-crossbow called BLOCKHEAD.
(V6 in the series)

It features a massive punch, while still able to use a true-trigger perfectly.
One can still detach the trigger to be able to fire 4 arrows in a row like the Reaper.

Although I was in a hurry (work after school \o/ ), the pictures should be fine.
Just in case I have a .rar archive included with all the full-sized pictures (2576x1932) in it, if you need to take a better look.


Extremely powerful
Long range
Very accurate
Perfectly working true-trigger
Very sturdy where it needs to be
Easy to mod


Not the fastest loading with trigger (goes faster once you get the hang of it)
The front handle needs improving
Its very heavy (dunno if this is bad =p)

Two video's, showing trigger and damage

Here is the .rar file

Step 1: Building the handle

Image 1: Build these two sides of the handle.

Image 2: Build the center of the handle.

Image 3: Different perspective; center of handle.

Image 4: Connect the side with the center.

Image 5: Different perspective; center + side.

Image 6: Add the other side to it as well.

Yup that's the handle, wasn't too hard eh?

 About how many yellow cons does it use?
In all honesty, about as much as my gun does... this thing dispenses with the need for solid rows by suspending the ammo with the RB's instead of using a track... also less solid-I built my gun to be usable as a hammer with no loss to functionality.
Wicky (author)  mettaurlover5 years ago
Kinda like this one, as in hammer? =d

Not so much-mine's shorter and doesn't have a bow, and has advantages in those regards-just as powerful, while being more predictable and lighter.

I found a typo! You wrote "Precision Crossbow" Instead of "Precision Hammer"!

okay , i'm done with it and it shoots realy hard !! i give you 5 * ;)
i like the gun realy much and do you have shoot on somebody with it ? XD i shoot it soem time on my friend ... ( with the sr-v1 ) .. bud tanks for it , i have a mod ... the scoop of the vss that is something that you must make !! it can use on every weapon and you can us it to the dragonflY on the top ... so meby you gonna try it ..
Dirtyboyy6 years ago
okay :D i gonna make it bud i just have 1 question for i make it XD th trigger .. can that break off .. ? becaus eyou need a lot of tape for it ... why do you need that for ? and on the uhm black/bleu connector from the trigger why do you need there tape for ?
Wicky (author)  Dirtyboyy6 years ago
Well it is perfectly fine without tape, but the strain will weaken the connectors after a while until it won't fire anymore, that's why I use tape. If the hinge connectors bend, the blue rod that holds the arrow won't come down far enough.
Dirtyboyy6 years ago
sorry for the questions !! bud shoot the dragonfly farhter than the sr-v1 ? and if you shoot on the wall break the red connector then ?? :D
Wicky (author)  Dirtyboyy6 years ago
It is capable of shooting just as far or further, but that would involve using the flights. And I haven't made a crossbow that didn't break the red connector on impact against a wall. And it doesn't just break it, it makes it explode.
Dirtyboyy6 years ago
okay , i think that i understand it .. bud i look to the ammo of the dragonflY and the gray conector on the end .. that can dissolve shooting isn't it ? so do you need there tape to ?
Wicky (author)  Dirtyboyy6 years ago
Connectors have sides which bend outwards when pieces are joined or taken apart, this cannot happen in the trigger because it is closed in tightly.
Dirtyboyy6 years ago
what do you mean with notr the strongest ? if i put now more rubberbands than er are ... breake it than off ?
Wicky (author)  Dirtyboyy6 years ago
The frame connecting bow and trigger is not very wide, and yes it may snap off.
Dirtyboyy6 years ago
sorry for that unclear questions bud i would now wich one the best is to make just the best .. :D i would a realy realy powerfull knex gun ( bow XD ) bud i can all your bows / drogonfly gun bow XD make just blockhead not .. so wich one is realy realy powerfull good trigger system not that it suddenly shoot away , and is realy great powerfull and strong ...

and i must say that you are the best bow maker are ever !!! 5* for all you rguns XD and i thins that i speak a littlebit unclear bud i'm dutch you know ;)
Wicky (author)  Dirtyboyy6 years ago
If under extreme force..like most of the time, you should put ductape on the red connector of the arrow. But this trigger type has no chance of firing prematurely. The Reaper is also insanely powerful, just not as advanced in trigger.(The video shows it shooting through wood.) I don't have any problem understanding you as I am Dutch too ;P
Dirtyboyy6 years ago
is it possible that if you reload it that it suddenly shoot away ? and how far does it shoot in meters ? or feet ?
Dirtyboyy6 years ago
wich one is the best off all your crossbows ( on this site ) because i like the dragonflY .....
Wicky (author)  Dirtyboyy6 years ago
I like the improved trigger on the dragonflY, but it is not the strongest, however slingshot weapons are way more powerful than weapons that use rods and tubes. This however should be the strongest.
Dirtyboyy6 years ago
allricht :D and i like you ! i post a comment and you anser me 50 minutes later XD how many white and yellow conectors do you need ? because than i gonna make it if i have inouch pieces :D
Wicky (author)  Dirtyboyy6 years ago
Problem is..I never counted the pieces, the only way one would know is to count them from the pictures, it should be easy though, as its completely symmetrical.
Dirtyboyy6 years ago
okay , i gonna make it ;) bud the trigger is not strong ( is that treu ? )
Wicky (author)  Dirtyboyy6 years ago
The trigger is one of the sturdiest ever made..to date it has never failed on me. I use it on all sorts of crossbows nowadays.
Hiyadudez6 years ago
nice crossbow, but my only prb;em with it is the trigger, i think the trigger is too complicated again... nice crossbow :]
Wicky (author)  Hiyadudez6 years ago
Take a look at the DragonflY, maybe you will understand it then, the trigger should fit perfectly fine.
Dirtyboyy6 years ago
does it shoot fahrter than 160 feet ? and looks funny 4.5
Wicky (author)  Dirtyboyy6 years ago
Well...it could if more rubberbands are added and is made longer..
Wicky (author)  Wicky6 years ago
Ow..I thought this was on my new Ible xd This can easily fire more than 180 feet
razzlekunai6 years ago
I am in the progress of making this. I was thinking about all the fun I could have shooting my neighbors, but a question suddenly formed into my head: What type of rubberbands does this use?
Wicky (author)  razzlekunai6 years ago
I never selected these on purpose, but these are just standard cheap small thin rubberbands:
Picture 052.jpg
WOuld #64s work as well, or can the trigger withstand only so much pressure?
Wicky (author)  razzlekunai6 years ago
I have a bad experience with bigger rubberbands, because they tend to flip the arrow around, but if you ductaped the trigger, it should be able to hold it I guess..only one way to find out though...try it =/
