Introduction: K'NEX Mauser SP66

Picture of K'NEX Mauser SP66

Having done a assault rifle for the past five instructables, I decided to go with a sniper rifle for my next build (#85). Once this decision was made (no pun intended), I decided to go with the Mauser SP66. I had originally intended to build a Mauser M86 (Mauser 86SR), but I chose to go with the "original version."

The original SP66 is 47 in. long, has a three round integral magazine, and is a very fine weapon but also very costly. My SP66 mimics the original in the fact that it is 47 in. long, has a three round integral magazine, and is a "very fine weapon," but it is also very piece consuming. I am entirely out of green rods, and while I do have black rods left, I don't like to mix these in with my builds.

- 3 round, blue rod, integral box magazine
- New scope setup
- Sturdy setup
- 47 in. long (full length)
- Fake bolt firing pin pull (adapted from BM2's KAR98K)
- Really great stock - super sturdy - super comfortable
- Comfortable thumb-hole grip
- Range (speculated): 40 - 60 ft.
- Looks just like a Mauser SP66

Internals will be added in the comment section below.

Let me know what you guys think!

Red, the gun rule

don't have your finger on the trigger unless you're shooting eue

Thanks man, glad you like it.

Yeah, no kidding.

I do like it bro, it's very awesome, I was/am experimenting with a good bolt mech, but I have up :/

Great! Can't wait to see it!

meh I'm building your Dragunov atm, but still, I'll see if I have some parts left to make a good bolt

Yeah, that is true enough. =D

Nice gun there Chris! I like the fake bolt action handle (You know how picky people are when they're talking about true bolt actions.) The pin could use a pin guide, though. It would make it more stable during firing. I'm the same way when it comes to green rods; I never like mixing them with black rods.

Thanks man, glad you like it! Yeah, the fake bolt makes it easier to operate, and adds a cool aesthetic to it. Yeah, we are of the same mind when it comes to green rods / black rods. My bro doesn't mind though, as can be seen in his G-MAL.

Another amazing project. I would have changed the barrel though, but I guess this was due to the lack-o-pieces-syndome?

Thanks bro! Yeah, I did the barrel that way for two reasons. In the first place, I had the lack-o-pieces-syndome, and in the second place, putting more pieces on the barrel makes it sag.

Thats true. I once built Motaboi's Intervention it had the same issue with the barrel with mine

Thus is life.

Very nice and amazing Red! That scope looks great :D

Thanks man! Glad you like it all!

Well, in that case, it is kinda one of those guns that you'd have to hold to really "pass a judgement" one. =D I have huge hands too (I can reach over an octave and a half... easily). Thanks anywho!

Whoa dude turn up on that scope tho!

Dat scope is awesome! Nice job!

Look good Red, if I was to make one change, it would be the barrel. Also I have just uploaded the instructions for the PM-63 RAK.

No problem, did you check out my PM-63 RAK instructions.

I haven't checked it out yet, thanks again!

Hmmm... first of all, it looks very awesome!

Secondly, thank goodness you finally made a good rod shooting gun :P! Now I will build this whenever you post the internals/instructions. (At first sight, I thought it was tubular mag gun, but then you said integral box mag) Where is the mag? I can't find it on the gun? Are thos tan connectors the mag pusher?

Finally, How many green rods does it use? I just want to make sure that I don't make unfulfilled promises on my list.

Overall, Awesome gun!

Thanks man, glad you like it!

I'll get the internals up as soon as I can bear to take it apart. =D

Where is the mag? Well, it is just above the trigger guard. I could get you more pics if you need them. The breach is above the magazine that is just above the trigger guard.

Well, as to green rods, I can't say. Close to 700, if not more.

Thanks again!

Mmmmmm yeah that thumb hole style grip.... yeah...... so awesome. I dig the sci-fi-ish appearance of the gun!

Thankee kindly! Glad you like it. =D
