Introduction: MBSR

This is the Masterdude Bullpup Sniper Rifle (MBSR). It is basically my MBAR on steroids (and a whole lot of them). It is stronger, more accurate, bigger than the MBAR but it is still semi-auto. The trigger mechanism has been modified for more power and easier firing.

Pros:
-Bullpup
-Comfortable grip
-Semi-auto (you choose you ROF)
-Removable mag
-Good power
-Good range
-Trigger guard
-OK looks
-Scope
-Bi-pod
-Sturdy
-Reliable trigger mechanism
-Large ammo

Cons:
-Uses a lot of pieces
-Takes a long time to load if you don't have experience (loading gets faster with practice)
-Rather large

Image 2: Connect the scope to the main body as shown.

Step 21: Loading and Firing

To load remove the mag and place the pin in the appropriate area. Now place the ammo in the mag. insert the mag into the ammo feed. Next push the white and blue rods in the ammo feed area out to the sides. Hook the rubber bands on the end of the barrel and the trigger spoke. Make sure the rubber bands are on both sides of the ammo. Once all the rubber bands are hooked push the white and blue rods back into the center. Remove the pin. Pull the trigger to fire (in case you didn't figure that out).

Note: This gun loads and shoots like my other semi-automatic guns.

looks A LOT stronger (by saying that i mean that about the trigger system) than your last gun! will build when after me and my friends have the next war :)

author
Masterdude (author)Seleziona2010-01-21

And once you build it you can use it for the war after that.

All your guns are basically the same. You should try something without the rbg mech, it's getting old.

author
Masterdude (author)The Jamalam2010-01-21

I'm going to post yet a couple of guns like this (Modded Uzi, maybe MP5, and maybe a P90 if my experiments go well). What would you like if I made?

author
The Jamalam (author)Masterdude2010-01-22

Hmm. You should try modifying the RBG mech maybe, making it easier to load or faster. Have a go at that, it should be well recieved providing it works well and improves on the old design.

"making it easier to load or faster"

By the faster in that sentence do you mean faster loading or faster shooting or something else?

author
The Jamalam (author)Masterdude2010-01-23

Faster loading would be preferable.

author
Masterdude (author)The Jamalam2010-01-24

You can load it very fast once you practice a little. How do you think I could make loading faster?

author
The Jamalam (author)Masterdude2010-01-24

Why don't you try something that captures the rubberbands at the end of the gun, brings them back as you fire and then puts it back on the snowflake for the trigger?
Maybe a removable mag too.

author
Masterdude (author)The Jamalam2010-01-24

Like the FreeSlinger?

Valkyrie103 (author)2010-01-19

So what's the range on this thing?

author
Masterdude (author)Valkyrie1032010-01-20

I don't exactly know but it is stronger than my other guns and I'd probably guess over 50 feet at least with my rubber-bands which where not really good so with new and good rubber-band you could probably get a lot more.

Mr. Muggle (author)2010-01-19

looks a lot better than the previous version

author
Masterdude (author)Mr. Muggle2010-01-19

The MBAR isn't an original version of this gun with this being a upgraded version but it is based on the same bullpup system.

author
Mr. Muggle (author)Masterdude2010-01-19

oh, ok, it's a good gun though

author
DJ Radio (author)2010-01-19

So all you do is make the barrel longer and add a bipod.  k.

Masterdude (author)DJ Radio2010-01-19

I also changed the ammo type, and made a improved trigger system.
