PM Mk16 SCAR-L by Hoborginc PM Mk16 SCAR-L by Hoborginc
Build a paper model of a third-generation FN SCAR-L assault rifle. Commissioned by rayegunn.
This model is 1:1 scale, consists of several distinct parts that can be disassembled, and includes some moveable components.
In addition to the rifle, an EOTech 551 holographic sight is included.

The complete model is 37 pages.

The download package contains instruction photos in addition to pattern pages in black, tan, and white.

PDF version (40 MB)

Q: What kind of paper and glue do I use?
A: 90-lb or 185-g paper, and regular white paper glue. Tacky glue also works, and dries faster, but may have more volume.
The pages (1700x2200), while larger than a page, turn out the same size on letter and A4 paper if automatically resized to printable area.

Q: Can it actually cycle a cartridge like one of tacome1942's models?
A: No. The moving parts do not replicate 100% functionality, they're just there for appearances.

Q: Can I attach accessories from other models to the rails?
A: Sure. The rails are pretty close to 1:1, so it's even possible to put real accessories on them (although this isn't recommended because of weight).

Q: I'm having trouble with X part.
A: Ask about it via comment or pm. Also let me know if there are any problems with the files.

Q: There are holes missing on the upper.
A: Here's the corrected page: (Black) (White)

Q: The right wall of the upper is backwards.
A: Here are the corrected pages.

Where are all the springs potitions?
Hoborginc Featured By Owner Aug 16, 2014
There's one in the butt (under the stock adjustment button, there's one at the folding mechanism of the stock (under the unlock button), but those are the only two necessary ones.
Anything beyond that is up to the builder.

Thanks, but where are all the springs potitions? (trigger, etc.) draw it if you would. Thx

The two that I mentioned have their positions shown in the instructional images for the stock: 06 and 14.

Adding springs in the receiver is optional, and I didn't test it. It's possible to place one on the spring guide (to push it forward, in effect pushing the hammer forward), although you'll have to find one that's large enough for this. It's also possible to put one on the rod for the mag catch, and possibly one under the trigger. In addition, it's possible to take a larger spring and place it behind the bolt carrier. However, these are essentially user modifications, as they aren't part of the basic model.

also i don't have to put the spring on the disconnector right?
Hoborginc Featured By Owner Aug 20, 2014
You don't have to put any of them in, except the ones in the stock.
Making the parts in the lower actually functional is up to you.

how the trigger works?, draw it plz, I know it's complex.
like when the trigger pulled back what will move?
Hoborginc Featured By Owner Aug 22, 2014
Here is the picture.
The front of the trigger holds the hammer in place.
When the trigger is pulled, its front edge goes down, freeing the hammer's bottom "foot" and allowing the hammer to swing up. To make the hammer move, there would (realistically) be a spring (shown in purple) on the spring guide.
If you want the trigger to be spring-loaded as well (to return itself to the forward position), you would need a small spring (shown in red) just under its front edge. Making enough room for it may require making some holes, so it fits inside the hammer and receiver floor, instead of between them.

How does the hammer move back down? The bolt carrier would push it back down as it moves backward. Realistically this would be caused by the gas piston pushing it after a shot, but on the model this can be done by racking the charging handle. Make sure you reinforce the charging handle (putting extra glue on it, adding some layers of paper on the inside, or putting a different material inside it) and the area where it attaches to the bolt carrier if you intend to move it frequently).

However, I haven't tested if the hammer, returning to cocked position, would be capable of resetting the trigger as well. It should, but if it sticks in place, you will need to use a weaker spring for the trigger.

The disconnector doesn't matter on a model like this (glue it down if it gets in the way).

can actually the v3 mag fits in the scar?
Hoborginc Featured By Owner Aug 20, 2014
Although it can probably fit, it will probably be too small and the mag catch won't engage completely.
