View Full Version : Custom MR3 MP7 "kit"...WIP and PICS.

10-05-2008, 01:35 PM
Maybe some of you already saw it:

Well I decided to make my MR3 into a "MP7" seeing as I don't have a decked out scenario gun. It was just laying around, stock.

So I am making my own "kit". So far I have the foregrip (non-folding :( ) and shroud almost done. I am going to make a retractable stock, and maybe a "receiver shroud". I may also make a mock mag to go under the asa :P

I know a guy on spyder.tv made an mp7 kit for his mr2. I think it was "slim and shady".

I PM'd him about how he did his stock, but he hasn't replied. So if you have ideas about how to make the stock be retractable and "connect" to the gun please post.

I kind of want to make the mag removable. So I'd need a mag well too. Haven't thought about it much so please post ideas.

Ok finally onto the pics.

Just with my modded airsoft m4 stock on there.

The shroud is made of balsa wood, putty epoxy, and a thin layer of sheet metal JB weld'd on. This will add a more realistic look when I paint it. The foregrip is just PVC and epoxy. Also just glued on some RIS

Wow, a lot of people getting into the scenario aka true side of pb :D! I would see if you could downsize the trigger-guard, it looks disproportionately large compared to the rest of the gun. Also, it would look sick if you made it side-cocking.

That looks pretty good, if you could get like the MP5 sliding stock here (http://www.opsgear.com/MP5-Sliding-Stock-for-Tippmann-A5-p/mi-stock-mp5-slide-a5.htm). I know its expensive but that would look awesome!!

10-06-2008, 02:18 PM
I'd rather just make one for that price!!!

Okay thanks slim and shady!

Yea I know what you mean, i am not good with my hands mine might blow up some how if I make one, I do want a sliding stock for mine to give it that SMG look

10-07-2008, 01:33 PM
Well thanks to slim for the idea I think I will make one quite easily. I have the skills and tools (not the brag :P).

Don't know when it'll be done by, because time is a major constraint.

10-08-2008, 06:21 AM
Let me know how you make it and stuff and what materials you used if you decide to do it. Yours would look alot like an MP7. SMGs are sick as heck

I still have to get you those pics my wife forgot the camera at her moms. So when I get it I will take them for you but the Idea is pretty simple. you need to attach it to the back of the marker in the same fasion the regular stock is and you want it to slid in as close as possible to the back of the marker. Because it is rear cocking you have to make sur eyou lkeave enough room to cock it. I will get pics soon as I can

hallow pipe and coldrol or whatever thats called. solid rod.

Makes sense, cant wait for the pic I been dying (literally) trying to figure out how to make one, i was getting ready to buy one for the Tippmann A-5 and just cut off where the push-in bolts go and sand down the middle nob that goes into the marker. But I would have to waste 100 bucks hat I don't have

10-09-2008, 04:31 PM
Thanks alot slim for helping me out.

I don't need the pics, because I got the general idea down, so dont hurry.

But they will still be nice :P

I think I will just make a rectangle to match the body and it will have a pipe inside it that attaches to the stock stocks adapter. Then a hole drilled at the bottom for the velocity adjuster to go in, so its flush.

Then the block will be a little thicker than the body, so there is a slot cut in it where both the stock "rods" will slide in and out of. Don't know hwo to make it stay in one position yet though.

And then I will make a replica of the stock (the actuall part that goes into your shoulder) out of wood.

Heres some updates, needs to be painted again though:

Looks sweet! You need to get some kind of eye covers though.

Looks great

un whats the hole in the front part of the trigger frame

10-10-2008, 08:28 AM
It looks real sick! The sliding stock would make it like even better. Post up the marker when you are done with! You should get a Trinity Clamping Feed Neck, GREAT investment considering I broke 4 of them in one day! I seen them the cheapest at amazon.com and paintball-discounters.com

10-10-2008, 12:02 PM
I am going to make some lexan eye covers because without the stock foregrip, it doesn't cover up the wires.

I may also mill and weld my own feedneck, and use hose clamps to lock it. Kind of ghetto but if works.

The hole in the trigger guard is for a switch. I did the auto response mod, but because I don't want it permanent, I soldered a switch to the circut. So once I mill out that hole, the switch will go there so I don't have to open up the gun to turn auto response on and off.

I am not finished yet.

I dont have time to make a good retractable stock, so I just made a non retractable one. And I use my CO2 as a "stock" :P


10-11-2008, 03:45 PM
That would look SO awesome if it was retractable. I personally don't like that suppressor but it looks sweet!
