Introduction: RMACR V.1 (Red's Mini - Adaptive Combat Rifle) (Internal Pics)

Picture of RMACR V.1 (Red's Mini - Adaptive Combat Rifle) (Internal Pics)

Hey guys. Well, I have been inactive for what seems to me to have been quite a long time, but here I am again, bringing you the RMACR. It is a smaller combined version of my ISSC MK22 RR, my Magpul Masada ACR, and Blue Mullet 2'sSIG552. It takes the same rail system from BlackShadow12's SWAT 556/my two guns above, and has at totally new (at least to me) mechanism. The gun itself kinda looks like a Micro Galil / AK-47u, but was not modeled after those guns.

I was originally going for a SIG551-A1, but my version looked too much like Blue Mullet 2's. It has tactical rails, is open to MANY different mods, and is THE most fantastic gun I have ever built. This gun rivals any, if not all, "simple pin" guns. This gun beats the S1, which as many know, is a great bolt action. I do not say this to brag, but it is just how I have found it. Lets move on the the Pros and Cons.

Shoots over 50 ft. with two bands (size 117, and a 32 thick)
Has tactical rails on top, sides, and bottom
Totally open to ALL mods
Looks great (IMO)
Sights work
VERY accurate
16 rd. mag
Not too piece consuming
Sights are simple
Not too heavy
Fires even will suppressor
Shoots rod-connecter ammo (dark grey connecter attached to a green rod, or you can just shoot white rods)

Mag requires tape
Stock is not mine

Well, there you have it. Enjoy! BTW, I would be VERY, VERY happy if you left your opinions here. Tell me what you think about this, also.

Hey hey hey HEY!!! this looks familiar. just played bf3 and looks like a sig 553

Really? Yeah, it kinda looks like a SIG553 doesn't it? What do you think of the gun overall?

Its actually good!

I am glad you like it. =D

Another thing, the handle/trigger looks like my style.

Yeah, you are one of those K'NEXers that helped me gain my building styles.

Thats great to know :)

Senior Waffleman (author)2013-05-02

Out of all your guns, this one looks the cleanest (In my opinion) This build style is probably the best for appearance, and as for performance, it seems to get good range. I like this one. Also, the trigger style you use, is very reliable, and I like it. As for the mag well, it looks pretty close to the one in my Sentinel. Good job on that part, and I like how theres no gaps in the gun, I like that it is filled. Thats what i like to do. As for the tactical knife, honestly, you couldve done a better job on that. And I wish you did, it would make the gun. I think ill try to make this gun from the picture, and ill tell you how it goes. As for the mechanism, I think ill try to add a pin guide of some sort, or change it a little so it doesnt stick out too much. Great looking gun, good job.


Thanks. This would be one of my favorites, and I am happy that you think it looks clean. I like this particular build style because of the many different ways you can edit/change it to fit your "needs." Yeah *smiles*, the tactical knife/bayonet was really lame. I really just threw it together for the idea, not because I wanted it to make the gun look cooler. Go ahead and give it a try. Tell me what you think, and thanks for the complements.

Any chance of a post? :D?

Sorry bro, it has been broken for a long time. I might build it again some time...maybe.

Really cool, wish i had enough pieces. Can you make something less "big" but similar?

I don't know...I am glad you like it. =D

Got anything to add? I see that you leave longer comments on BM's stuff...why not give me the same attention? XD I'm so heart broken at your neglect! XD

Well,I see two guns in one here, one is the mini acr you built it to be and the other with a few changes is an akm74u. It would be awesome if you could add a mag release but I see that could be kind of difficult. Only other thing I can say is that it needs to be made of metal and shoot 5.56 nato =p

Yes! I totally agree.

So how is the uzi going?

Ah, we stopped building it a while ago. It was just too hard.

Thats the only problem with the smaller smg's. Its not easy to set up a good trigger, add details and get a good range. I've been working on my mp5k for a long time now and I almost have it complete,it took me about a year to get it even close to the real thing. The next compact gun I need to complete is the ruger mp-9,I got everything but the trigger.

True dat. In general, pistols and SMGs are just too small to fit a good mech in. That is why people freak out when a good looking pistol or SMG is created. I really can't wait to see what you come up with on that MP5k PDW. It looks and sounds so cool. As to the MP9, I love the looks of that gun, and again, I can't wait to see what you come up with. =D

For the mp5k pdw I probably wont be able to get the stock to fold. Another awesome thing I want to build for my mp5k is this.

A CASE FOR YOUR MP5K PDW!?!? THAT WOULD BE AWESOME! Don't worry about the folding stock, it is not that big of a deal.

The case is basically designed to turn it into an assassination weapon. The fun part (sarcasm) will be adding the trigger mech to the case.

Hows that MP5K coming along, I am anxious to see it!

I need some ideas for the trigger on my mp5k,its a really tight space to work with. Sadly I couldnt the the mag from the version before this to work.

Now that is what I call an awesome gun!

Thanks man. Hows school and life as a follower?

Your welcome. School is busy. It's taking up a lot of my time. Life is crazy. Since June of last year I've moved 3 times and now am going to move again here soon.

Holy cow, three times, that is CRAZY. 0.0

Very nice overall. However I will repeat this again. That type of connector ammo almost never works for me. But those guns are always easy to make into guns using the ammo used by KillerSafeCracker's Thunderbolt rifle. All that said and done it is a sweet looking gun and wish to see instructions posted soon

Thanks bro. Well, this gun shoots the ammo seen in the pic 60 ft. but this mag also works with white rods, if you did not know. Thank you so much, I am glad I could please you. BTW, when are we gonna seem some stuff from you?

Unfortunately I don't make new guns. However I am very good at making guns better. The closest thing to a new gun is a heavily modified logic bow that acts like a shotgun. It is simply a better version of this gun.

Awe, that is too bad. Well, any time you post something, just let me know. =D

Will do.

LOL i was just thinking- "Damn- how can i get him to post this(then i noticed the internal pics)" great job!

XD "Damn..." Thanks man. =D

Your welcome

I like this gun very much. 10/10. Would be great if instructions were posted. I would defanitly build it :)

Sorry, its broken. I am working on a new gun right now.

Shame, the first picture I look at took my be suprise. I immediately thought wow this is a gun. :)

Yeah, it is a shame. I am glad you like it. I built a G36C, why don't you go check it out...?

The internals are right flipping there...?!?!?

RAWR lol, whats so cool about it though?

Oh co....nvm.


dr. richtofen (author)2013-03-18

Interesting trigger. Though I recommend using a cut-in-half broken green rod in the orange connector, to keep the tabs from breaking.
Overall a very nice gun

True, true, but it isn't necessary, and it works fine the way it is. Thanks BTW.

No problem :D
