Introduction: MPR-12

Picture of MPR-12

This is the assault rifle that i looks a bit like an AK47 but its my own. It was originally based on killer~safe crackers monster pistol but i changed it over the coarse of a week and it became this beautiful weapon. It also uses a slightly modded version of his curved mag
Here are the Pros and Cons of the gun

Pros: good range for a mag fed gun (25-50ft depending on rubber bands)
very powerful
10 or 12 round magazine

Cons: the bullet spins a bit decreasing its range and accuracy slightly
a little big and heavy (not good for maneuverability in battle)
too sexy to stare at for long periods of time

here is an awesome video made by matsermetsuiker

Step 1: Body

this might get a bit tricky if you don't look closely.

Step 2: Handle

Picture of Handle

very easy and if you want you can use medical or duct tape for more comfort.

Step 3: Stock

make. self explanitory

Step 4: Magazine

both the curved and the strait ones are good but you should use the strait one in close combat because it holds 4 more bullets and it is much more reliable and the curved one in multi floored combat situations just in case you need to use the bipod since it doesn't have the rod sticking out. just build it from what you can see, its not really in order but the curved mag is first.

Step 5: Barrel

Picture of Barrel

it doesn't stop the bullet on accident but it uses a lot of orange connectors so you might need to make it shorter.

Step 6: Extras

band placement, scope, and bipod. (i don't like the scope so i prefer to leave it off)

um i dont own a rare 1500 dollar carpet... is there another thing i could use in its place?

mikstr2 (author)sirvyvin2011-05-19

a potato chip will actually take its place quite nicely, so you can always try that.

sirvyvin (author)mikstr22011-05-21

mikstr2 (author)joeyay2010-08-11

Torpe (author)2010-07-28

~Aeronous~ (author)mikstr22010-06-24

You are a fxcking genius. I didn't want to say God, because I might offend my religious friend.

mikstr2 (author)~Aeronous~2010-06-24

it was actually killer safe crackers idea but i changed it so it didn't have the mag pusher hanging out and i think i was the first to post an ible with the curved mag

~Aeronous~ (author)mikstr22010-06-24

Nah you weren't the first, but you certainly are the best!

Dr.Squirrel (author)2010-03-16

mikstr2 (author)Dr.Squirrel2010-03-16

Dr.Squirrel (author)mikstr22010-03-17

Why??? Iwas going to make them!!!

mikstr2 (author)Dr.Squirrel2010-03-17

Dr.Squirrel (author)mikstr22010-04-08

I've built it, didn't work out, hate the mag system (broken pecies)

mikstr2 (author)Dr.Squirrel2010-04-08

oh yah... i made a put together a new way of making the top of the mag so it doesnt use any broken pieces but i never got any pics up

Dr.Squirrel (author)mikstr22010-04-08

 Dang..I took it apart for the WW2 Springfield already...

insanecreator92 (author)2010-04-03

mikstr2 (author)insanecreator922010-04-03
