This gun is Alingarhs Mx8/FN scar. I really like it so i built it and made modifications. The mods is the barrel, stock, front hand grip, sight, and a mini grenade launcher. Great accuracy. If u like the gun then plz try my mods you will see its really cool. So ya i hope you enjoy. And this is the site for the original gun; ok plz rate my instructable ty. _Undermig_

Step 1: Stock

You can put 2 grenade launcher each side but i like more 1 side for thum. Sry for flash...

Step 3: Back Sight

Sry but its writed cool gun and i cant delete it...

Step 4: 2 Front Sight+ the Barrel Extention

Make the barrel longer=more accurate. I think u can continue the barrel with the orange connecters but i don t know if its the same distance. But it still goes well. Good shoots.

Step 5: Together

Just add the piece like in the photos.

good grip but not good grenade launcher you should make the launcher out of gold 5 slot connectors with nubs on white snowflakes that would make it able to fire lots of airsoft pellets or other ammo

The XM8 and the scar are two different weapons.

Personally, I prefer the SCAR.

Undermig (author)ILIKEPIE3332008-11-28

...LOL i know its kinda fuzion HAHA

maxxxem (author)2009-01-31

very nice

Whaleman (author)2008-06-20

It is an XM8, not Mx8. The Masada owns it anyway.

ILIKEPIE333 (author)Whaleman2008-11-27

bannana already said that

Mykhailo says: Jun 20, 2008 bannana inventor says: Jul 18, 2008 Correct me if I'm wrong, but June comes before July. Besides, what is the point of coming back on a thread a few months old and telling me this?

ILIKEPIE333 (author)Whaleman2008-11-28

Oblivitus (author)Undermig2008-08-10

No, I only design my own guns at this point, I stopped making other peoples weapons a while ago unless I am going to do some serious modifying to it that is.
