This is my MSAR-1 (Masterdude Shotgun/Assault Rifle model 1). It is similar in design in many ways to my MAR-4, however it has many new things which make it different from it. It functions as both a shotgun and a rifle, depending on the ammo you load it which depends on the mag you use.

More instructables by Me

  • Assault rifle
  • Shotgun as well (without modding the gun, you only need a separate mag)
  • Removable mag
  • True trigger
  • Iron sight
  • Can store another mag in the back
  • Breech loading hatch
  • Cocking handle not joined to firing pin
  • Cheek rest
  • Adjustble dot scope with cover
  • Vertical grip
  • Accepts MBAR-2 Gear (bipod may need some changing but can be attached)
  • Lots of pieces
  • Not semi-auto
  • Range for rifle ammo not too impressive

You can get more gear from the MBAR-2 Gear.

Step 11: Use & Operation 1

First attach the rubberbands as shown in images 1-3. Then load the magazines, the rifle magazine (image 5) with the ammo (image 4), and the shotgun magazine (image 7) with shotgun ammo (Image 6). Then insert the magazine (like in images 8 or 10), and take out the magazine pin ,and then pull back the cocking handle to cock the gun as image 9. Then pull the trigger to fire. Pull the cocking handle back and repeat as needed. To manually, single, hand load the rifle, pull up the ammo hatch on the side as in image 11, insert the ammo, and then close the hatch.

Is there a piece count?

Could you be more specific, as in what do you mean by "f t e"? Are you saying "first time ever" by that?

Read both parts of the "Power" section.
Masterdude (author)  oodalumps3 years ago
If you are telling me that the pin is too large and that no barrel would be better, yeah, I kind of know but I was trying to make a kind of compromise between power and other stuff. Without barrel it would be difficult to have a spot to attach extra gear and I wanted a side cocking handle which would be detached from the pin itself. While both negatively impacted the gun, I deemed the sacrifice of some power worthwhile.
You could make the middle section of the gun longer, and still keep the barrel exactly the way it is.

The part on the pin that makes it too big has nothing to do with the priming handle. You could just as easily just a ball socket.

Thank you for disconnecting the charging handle from the firing pin!

You're welcomed.
Why the heck do you post the same gun over and over again?
Masterdude (author)  Raz1r Knex Bull3t3 years ago
Excuse me but I don't post the same gun over and over again. You may think so since they tend to have similar characteristics since I have a certain building style and usually use parts from previous guns, but they are different in certain aspects. I have already heard people comment on their belief that I lack innovation, however when I post a new gun, I post it since it has new features which are absent in previous guns. Sure, half the gun is similar to the previous MAR-4 from which it is based off of in some design aspects but it has an improved firing mechanism which others have commented that I should impliment, improved gear and sights, and many different and new things which make it NOT "the same gun". As for any future comments I suggest that you and others take into consideration the facts before commenting.
Yeah, um, hey Sherlock Holmes, what you stated about your gun are just mods. Don't act like I'm so stupid. A gun like this doesn't need a whole other ible to post some mods, is it that hard to add them to the previous ible for the original gun.
I feel like this, you state, "improved gear and sights," I think, "Big, whoop, you put new sights on it." So what if you made new sights, you don't need to make a whole new ible about it. You must have never heard the word "mod" have you.
Erm... it's an improved version of HIS gun. If someone else was to post this, they would post this a mod, But since Masterdude posted this, he has he right to post this as a seperate gun. Try to take into consideration Instructables' "be nice" policy before you comment as well. Anyway, good job Masterdude - 4.5*.

Thank you for the compliment and thanks for supporting me and pointing those thinks out.
No problem man.

I meant "things", not "thinks".
Masterdude (author)  Raz1r Knex Bull3t3 years ago
I could have made this a "mod" I'ble. However it would force whoever may wish to make this gun to first go to the previous gun, and then take certain parts of the gun apart, only to put them together again. This way it would save whoever may wish to make this time and trouble. And yet again I would have to point out that it isn't only some minor changes like a new sight. If I made a new sight or gear I would have posted a separate I'ble such as my previous "MBAR-2 Additions". If it were just as simple as replacing some parts of the gun such as the magazine with a new one I would have made it like my "MAR Mod: Gray Connector Ammo". I would now like any more discussion on this topic to be made by PMing.

That firing pin is HUGE.

TUMOR pin.
Masterdude (author)  Mepain3 years ago
Actually it isn't all that large. That is one of the things I changed, in part due to a request on a comment. The one on the MAR-4 was larger, but this one may look "HUGE" because the cocking handle is shown right next to the back of it. The Cocking handle isn't fixed to the firing pin so I wouldn't exactly consider it part of the pin.

This isnt even a gun anymore.
