Barrett M107 .50 BMG 3.5





Introduction: Barrett M107 .50 BMG 3.5

About: I'm an intermediate knexer who builds replica guns and performance guns. If you would like me to make a replica of a gun, just ask. If you would like me to build your gun and review it, just ask. My gamertag...

Final version. Instructions suck. Read Image notes. Sorry. \

Range: 65 Feet MAX
Power: Decent
Size: around 4 1/2 feet
War weapon: Oh god. hell no.
Fun: invent new meter-broke current one

Working on Christmas replica, comrades. Reznov liked to use this gun in WWII. *Hint* *Hint*

Step 1: Muzzle Brake

Note the structure and How it connects to the barrel.

Step 2: Bipod

Note the rubber feet. They are nessesary if you want the bipod to work. This was influenced by the Z35 bipod.

Step 3: Carry Handle

Don't try to carry it with this.

Step 4: Shell

The sides of the gun.

Step 5: Inner Barrel/Front Section

Exactly what it sounds like.

Step 6: Guts

The middle part.

Step 7: Stock

Pin is in here.

Step 8: Scope and Mag

Both modded from motaboi's cheytac m200.

Step 9: Fake Charging Handle

Fun to rack.

Step 10: If You Could Build This.....

Not to diss your gun butt my instructions are easyer

This is still being made three years after you posted it. :3

Thanks for the mini tut everything was easy to see and build I only had a problem with the barrel and ammo pusher

well if u make the part where the carrry handle connects to the gun stronger u can use the carry handle

Looks good but the front barrel isn't very good... make it 4 or 5 layers, I swear, I'm building my own version right now and used first a 3-layer barrel with 7-way coneectors too, but I didn't even get 3 feet range or something... :P
Just use 4/5 layers if you're gonna build a long gun like this.

it got good range for a three layer barrel. I was more concerned with the gun being realistic than operating well, but it does operate quite well. 65 feet with a slight angle.

I would prefer to build your gun rather than mahmel barrot 50 cal because i built his and it didn't work and i think the barrel looks really good, love your gun 5*.

Nah i can't believe that, there's way too much friction and 7-wayconnectors have also little dots which makes it even more harder for the the bullet to fly through the barrel.

Again, I can't believe it. And that's nice said. Video please.

I'm not gonna rebuild it just to make a vid of range. If you don't believe it, that's fine. It is the internet after all. If I do not back up my claims with proof, you have every reason to question the maximum range.

Nah, I don't think you did. You don't have to be sorry for anything.

omg just looking at pics of it and tht is the best looking scope that i have ever seen on a knex sniper
