technically every gun on sight is block trigger because every gun has something to block the firing pin

author
maxxxem (author)fobblewabble2008-12-16

not all of them

author
iKill (author)maxxxem2008-12-16

ya your completely wrong, there are plenty of guns that use whats known as a sear system which is the complete opposite. oh ya and has anyone noticed that people are posting "grenade launchers" that look eerily similar to crappy block trigger guns

author
The Jamalam (author)iKill2008-12-18

? sear triggers are still blocking the firing pin

author
iKill (author)The Jamalam2008-12-18

no they arent they hold it back thats not blocking, block would mean to get infront of it.

author
The Sensei (author)iKill2013-07-02

this is exactly true......kind of. all knex triggers are technically BOTH block and sear, being that an object "blocking" the pin at some point must move in a "searing" action to allow the gun to fire. but the main point is like you said, a "block trigger" here is one that has something in front of the pin to hold it back, whilst a "sear trigger" is one that holds on a small latch type mechanism on the rear of the pin. sear triggers are notably more difficult to design, however they do produce much better results in firing. (they also very rarely break firing pins!)

The Jamalam (author)iKill2008-12-19

its blocking its path by getting in front of at least some part of the pin

author
Mepain (author)The Jamalam2008-12-20

A trigger that is a block trigger blocks the pin from the front; this is the term that we have adopted. You're getting too literal with the term. Block- blocks from the front. Sear- holds from the rear.

author
The Jamalam (author)Mepain2008-12-20

the whole point of a term is that it is literal! I know wht they are

author
Mepain (author)The Jamalam2008-12-20

The whole point of the term is to identify a part of a gun. When playing tug of war, and you are holding the end of a rope with a knot in it (hand in front of the knot), you do not "block" it, you hold it. The same goes for a sear.

Not all, but most.

true

yaaa.

err, not every gun is. My crossbow uses a ratchet slingshot system. RBGs are not blocks either.

author
bounty1012 (author)DJ Radio2009-08-13

yes rbgs are technically, they got some sort of mechanism that blocks the cog from turning.

author
nerfdude (author)bounty10122009-08-30

Some RBGs don't even have cogs or gears, but instead are more like a sling shot.

author
fobblewabble (author)DJ Radio2008-12-21

someone already said that. I meant guns like this!!

author
An Villain (author)fobblewabble2009-07-05

sear system guns are like this but they lock the firing pin in place, look up knex p90 desechos by M16.

author
The Jamalam (author)fobblewabble2008-12-18

nope. what about guns that don't have firing pins? or true semi autos?

author
fobblewabble (author)The Jamalam2008-12-18

this gun is a block trigger, not a push trigger where the heck did he get that from?

author
psharpep (author)fobblewabble2009-07-04

Well for me it's easier just to tap the barrel of my gun than find a trigger and pull.

author
DJ Radio (author)fobblewabble2008-12-20

you have to push the trigger to fire it.

author
fobblewabble (author)DJ Radio2008-12-21

On every other normal gun you have to pull the trigger. Why isnt it called a pull trigger instead of a true trigger.

author
DJ Radio (author)fobblewabble2008-12-21

pull triggers do not use hinges, you just pull it back, and you let it go to shoot. True triggers use hinges.

author
ILIKEPIE333 (author)DJ Radio2009-03-01

what? how does that make sense? As you explained it, pull triggers are not triggers at all then

author
DJ Radio (author)ILIKEPIE3332009-03-01

yes, i did mean it like that.

author
ILIKEPIE333 (author)DJ Radio2009-03-01

ok

author
fobblewabble (author)DJ Radio2008-12-21

My next queshtion is... How is this a grenade launcher?

author
ILIKEPIE333 (author)fobblewabble2009-03-01

no clue see my top comment

author
fobblewabble (author)DJ Radio2008-12-21

what?

author
ILIKEPIE333 (author)fobblewabble2009-03-01

I know!

author
psharpep (author)The Jamalam2009-07-03

Well that would be amazing, but you would need some sort of energy supply to pull back the firing pin. A motor maybe? Hmmm...

author
The Jamalam (author)psharpep2009-07-04

Or the rotary motion of a trigger!

author
psharpep (author)The Jamalam2009-07-04

Yes that's what my second comment is about. But it'd need to be a large trigger or you wouldn't get much power.

author
psharpep (author)The Jamalam2009-07-03

Or, we could make a gun where pulling the trigger back pulled back the pin and released the shot at the end.

author
dsman195276 (author)fobblewabble2008-12-17

but the name block trigger was given to the ones you turn.

author
maxxxem (author)dsman1952762008-12-21

yes and the one i made does NOT turn

author
DJ Radio (author)maxxxem2008-12-21

you can mod it to turn though.

author
Bartboy (author)fobblewabble2008-12-16

All of them but slingshot guns.

author
The Jamalam (author)Bartboy2008-12-18

and rbgs, and true semi autos?

author
Bartboy (author)The Jamalam2008-12-18

Semi autos are different, and rbgs work the same way as slingshot guns.

author
The Jamalam (author)Bartboy2008-12-19

not the same. semi auto rbgs are different

author
Bartboy (author)The Jamalam2008-12-19

Rbgs work the same as slingshot guns!

author
The Jamalam (author)Bartboy2008-12-19

NO THEY DON'T! Slingshots use rubberband energy to propel the ammo forward. RBGs Fire rubberbands with a different mechanisms. semi auto rbgs have a pinwheel

author
DJ Radio (author)The Jamalam2008-12-20

My crossbow uses the same mech as my SPEC-9 pistol.

author
Bartboy (author)The Jamalam2008-12-19

They both have the same type of trigger with a cog, if it has a real trigger.

author
pie25x (author)2010-06-17

I made this and when I fired it without ammo, the pin shot out farther that my gun

author
Dashadower (author)pie25x2012-06-23

LULZ! That would mean your gun would need some touching up!

author
knexlegowizard101 (author)2010-08-06

theres one extra pice what do with black y thing

author

right were it says "push to fire". =D
