Introduction: K'NEX Magpul Masada ACR V.3

Picture of K'NEX Magpul Masada ACR V.3
ACRs (Adaptive Combat Rifle) have, for the longest time, been my favorite type of assault rifle. The "real ones" have such a cool looking, not to mention modular, frame, and their many abilities just make the guns so cool. My favoritism can be seen when looking at my instructables. After all, I have posted at least 5 ACR based guns (Magpul Masada V.2, RMACR, R3, ISSC MKII RR, and last but not least my RLSW), none of which have deviated too far from my first (fully fledged) ACR.

This would be the third Masada that I have issued to instructables users, and has many improvements over earlier designs. In the first place, the mech is much better as it now includes a "knock off" version of my RMACR's internals. In the next place, the stock and overall body design are much improved and are infinitely sturdier than my earlier versions. In the last place, the sights are now full flip up sights, and can be activated at will.

- New flip up sights
- New grip
- New cheek rest
- New set of internals
- 16 - 20 round magazine
- Great pin-pull length
- Great range (the previous version's range was rather far fetched): 50 - 60 ft.
- Great stock
- Really modular body

I'll get internals to you guys shortly.

Really nice. Ive always wanted to build an ACR but never took the time to / I didnt know how to approach it. With that being said, you did great! Keep up the good work!

Thanks man, I'm glad you like it! You still got Infinity?

I dont. BUT i have the pictures for instructions. Ive procrastinated on it hardcore. Cuz I bought Diablo 3, and I got Deadspace, so ive been playing those. Lol. I try to get on here often, but there wasnt many new things until just a while ago.

Oh, O.K., good! I can't wait to see the internals (as if I won't build the whole gun!?!?). Is Deadspace any good? Do you got anything built ATM? I have

(Whoops, I accidentally posted that comment before I was finished) As I was saying, I have an AK-12 and a new FN Five-SeveN (yes, the last "N" is supposed to be capitalized):

Deadspace is pretty cool, I only got a few minutes in since I had to go. But Ill probably be playing it more. Idk. Im working on a project that I have been wanting to build for a long time. Im gonna keep it a secret unless i really need some help. Yeah :P but if I do need help, ill PM some people I know.

Alright, sounds good bro. =D

He's alive : )

I am :P just been playing video games, lol

That sounds entertaining, I thought you had left.

Nahh. Just lazy

I like it : )

Thanks man. Are you working on anything ATM?

This = )

Looks like... kinda like a... I don't know... a Russian gun. What can it do?


Lol, it does have a little bit of Russian style(blocky) I guess. It also fits into the #lolwhynot
Helpfully hint, v2 of something I recently made : D

Awe! No way, that sounds boss!


Lol, yes way, I will make sure to make a video for this one =)

Great range (the previous version's rage was rather far fetched): 50 - 60 ft.

lol reread what you posted

Yeah, I corrected that. =D

wow 50-60 ft of rage is quite a bit! XD hehe

Yeah, no kidding. =D

hehe wow thats rediculous

Rage XD

Beautiful work once again, Red. The thing looks like it uses quite a bit of bands to hold itself together, but the awesome range definitely makes up for that rubber band usage. In other news, I've got K'nex again, and I built a thing! Hoorah!

Thanks man! I'm glad to see you are back to join into our conversations! As to rubber band usage, only two of the bands you see have anything to do with my gun, the other ones just keep the side panels on.

Yep. I was just pointing out that there were a lot of those.

ooyeah, everything is awesome, except that I like the stock better in your V1 . but keep it up :)

Yeah, the V.2 stock was nice, I just like this one better. Thanks again man, BTW, you havent posted in a while, whats up?

school, and I'm looking at other instructables outside of knex, like art, technology, etc

sandroknexmaster (author)2014-03-27

Looks awesome!

Dude, what a spot on replica! Good work man!

Thanks man! I'm glad you like it!
