M-12 SABRE (Demonstration)

I am showing off my new K'nex rifle, the M-12 SABRE.

It is a fairly large gun, originally built as a sniper rifle but became a semi-automatic rifle later.
It features a 9 round magazine not designed by me, but it is used so much that i do not know who designed it first. It also features a block trigger mechanism connected to a true-trigger, which i know everyone hates, but it works very well, and I myself hate the Sear mechanism.

It has a pretty comfortable and effective stock, but for the younger people you may want to shorten it.
The scope is just for show, I wouldn't recommend aiming with it.

As for power, I designed it from the start to be very powerful. How? It features a ram rod of black grey length, which can be pulled back further than many other rifles out there. This is more powerful because it allows for more elastic energy to be built up since they can be stretched further. This also allows more time to transfer that elastic energy into kinetic energy as the ram is released. I have also made the bolt "rod puller" able to move back to the starting position after the ram is pulled back, therefore making it easier for the ram to pick up speed since it does not have to push the bulky bolt forward.

The gun also has a very high capacity for elastics, at first the bolt will seem very hard to pull back, but it is designed so that when you are holding the gun properly (butt in shoulder, rifle straight in front of you) it is very simple to hold the gun with one hand on the front grip, and use the hand on the side of you that the butt is against, and pull back to bolt with that hand. The bolt may seem a little flimsy, but if you have the palm of your hand touching the curved part, and some of your fingers more towards the center, it will work perfectly.

Please say If you think that i should post this as an instructable, I will need to hurry in order to make it before I leave for vacation for a month and then moving overseas.

Posing today in the pictures is my brother, Patrick.

Cool pics. Cool gun. It doesn't seem the best though, but it does look good.

Myself, I do not think you should make instructions. In all honesty, I think you can do better. ;-)

Sorry, 2008. Never mind!

Not semi-auto, but other than that it looks good.

doesn't semi-auto mean that it has a magazine? well it does.

Jul 18, 2008. 10:47 AMjollex says:

No, semi-auto means that it shoots one bullet for one pull of the trigger without pulling anything back. If it has a magazine that means it is auto-loading.

My instructable for the rifle is here. I hope that I did everything correctly, this will be my first instructable.

reminds me of the gun from gears of war's cover. everyhitng in that game is way to big like this gun. but big is a good thing imo

the lancer rifle? Nah. Big and small is both good in different situations.

That mag was made by hack124x768, and it has not been used too much. The last thing I remember it being used in was a remake of hack's original gun.

Jul 16, 2008. 1:13 PMknexguy says:

Nah, I think it was on that gun with the barrel on the bottom of the frame.

Jul 16, 2008. 2:21 PMapples!!!!! says:

the modded jager and deviant rifle used it

Jul 17, 2008. 8:29 AMknexguy says:

Yeah, think I've seen it on there.

Jul 17, 2008. 3:07 AMDutchj says:

That stock is way too short already. I don't think anyone will shorten it even more. It's a decent rifle, but I've seen better.

Jul 17, 2008. 4:14 AMoharaandrewlp (author) says:

You'd be surprised how long it is if you hold it properly. I'm 16, and it's a good fit. This is my first completed rifle, so it's not going to be THAT good.

Jul 17, 2008. 5:16 AMDutchj says:

I know how it should feel, I've made my own rifle too. And I know how a real gun should feel. You don't look 16 though.

Jul 17, 2008. 6:22 AMoharaandrewlp (author) says:

If it makes you feel better, you can extend it when you make it. By reading the description, you might notice that at the bottom it says "Posing today in the pictures is my brother, Patrick."

Jul 17, 2008. 7:14 AMDutchj says:

Wow, I can't believe that very last note is the only thing I didn't read. I think I read it before you edited that in, because it says: posting today, so it wasn't always there.

Jul 17, 2008. 2:11 AMoharaandrewlp (author) says:

I'll try to have the instructable posted today. I'm done with the magazine, bolt and firing tube assembly now.

Jul 16, 2008. 10:14 PMplasmaspy says:

really nice. thats my favourite type of mag also.looks pretty good id love to build. post please! =] +5

Jul 17, 2008. 2:10 AMoharaandrewlp (author) says:

yes, it's my favourite too. Sure the rods may go flying out in every direction if it jams, but it's very easy to un-jam.

Jul 16, 2008. 3:17 AMoharaandrewlp (author) says:

The images do not seem to be appearing, can someone say if they can see them?

Jul 16, 2008. 10:39 AMTrauts says:

The images do appear for me, but the last half of them go blackish and you can't see them.

Jul 16, 2008. 1:34 PMoharaandrewlp (author) says:

ya I can see them now. the last few aren't the technical ones, they just look pretty cool, and give you an idea of how big it is compared to my brother.

Jul 16, 2008. 10:15 PMplasmaspy says:

mmmmmmmm i can see all pictures completely perfectly clear

Jul 16, 2008. 1:33 PMoharaandrewlp (author) says:

It really depends on what elastics you use and how you use them. I am using one long one, and three short elastics. There are different notches under the ram to hook the elastics for the best effect. I did a really rough estimate of what the rifle shoots. I counted out 16 paces, say one pace is bit more than 3' , that's like 53'. I've got 2 full days until I'm going on vacation, I guess I might be able get the instructable done by then, I might get in some upgrades on the way too. Any suggestions?

Jul 16, 2008. 12:19 PMThe Jamalam says:

i think that you should definitely post this

Jul 16, 2008. 12:17 PMThe Jamalam says:

the mag was made first by hack124x768 on his osnjckma2 rifle

Jul 16, 2008. 11:02 AMcodemaster2590 says:

I like the rifle and the stock espectally. The one think i think you should do at this point is add more pictures so if people are likeing your rifle they could build it before you come back from vacation. About how far does it shoot though.
