loading
This is my MAR-4 (Masterdude Assault Rifle version 4). Upon request of fellow members of the K'nexing community here, I have made it using a new firing mechanism (firing pin/ramrod type). It fires my standard ammo, however if you are doing single shot then it will shoot blue rods, and others if you load down the barrel.

Features:
-Adjustable sight
-True-trigger
-Trigger guard
-Cheek rest
-Removable magazine
-Vertical grip
-Good power
-Can be breech loaded

nice!
On the other side there is a flap/breech which can be used to single load the gun. You can see it in the <a href="http://www.instructables.com/id/MAR-4/step8/Operation/">8th Step</a>.
pretty cool feature =D
Looks epic man 5*
Thanks.
No problem XD I like your latest bullpup SMG =)
Thanks. SMGs are nice, but bullpup makes them even better. &quot; =) &quot;
I like bullpups, but my fav is the F2000 =D I like using smiles XD You should see some of my things.
Good job. 4.5*
Why did you reply to that?
i didnt mean to
Its alright, thats happened to me before =D
Thanks.
now this looks AWESOME!!!!!
Thanks.
This is really great! 5*
Thanks.
Np. i really like the side loading mech!
Thanks. I wanted to make something new and more-less practical. Now you can load without removing the mag.
help! my gun wont cock! it just slips past the trigger! help please!
I don't know what's wrong, but it may be that you don't pull the charging handle thing back far enough, or the trigger may not be pushed enough by the rubberband (then get a stronger rubberband on it). I hope that helps, if not then PM for further assistance.
Can anybody make a piece count? i don't wanna build it to the end and not have enough for something.
ok thanx
You're welcomed.
Do u only need 1 Y connector for the whole gun?
Unfortunately no. You need 6 I think for the removable mag, however if you can't manage 6, you could mod it so the mag is not removable and you wouldn't need any, I think.
I built it and loved it except for one thing range. I love that you are making ramrod guns but next time make it so the ram rod isn't attached to a charging handle and then the range will be much better. And could you maybe build a good pump action gun? If you do that would be great!
I know the range isn't as good as in my previous guns. Currently I have made some new ramrod guns and will post them later. They however are more compact and are side arms.
OK well then keep on working on this one and try to make a better second version.<br>
On the MBSMG, do you have to pull back the bands/pin for every shot?
No, only when loading. Also could you comment/ask about an Instructable on that Instructables page?
will you be making more guns like your othher ones (mars mbar, msmg etc)
Of course. However they will probably only be coming back in a few months. I have now created a mechanism which works well enough for me and the next few guns will be based off of things that I've developed for this gun.
When you dot, make a pistol!<br>Call it the MSAP!<br>
I probably will. However I may call it the MSAU-3 like ones before it. What general characteristics do you think I should add to make it a MSAP, not a MSAU?
a very short barel (7 cm)
Anything else?
For realism, have a slanted handle as the mag, and please DON'T use the same mechanism that the MSAU uses. (not the pseudo, i mean bullpup)
I'm working on a slanted handle (will probably not have a removable mag). As for the trigger I will try making a ramrod/firing pin mech first, then maybe a semi-auto.
a removibale mag inside the handle and no foregrip
On the other side there is a flap/breech which can be used to single load the gun. You can see it in the <a href="http://www.instructables.com/id/MAR-4/step8/Operation/">8th Step</a>.
On the plus side you're starting to put variety in your designs, but on the minus side this isn't anything new or special.
The side breech loading is new and the mech. What would you like to see me make into my next guns?
What side breech loading?

i mean the semi auto mech
