K'NEX Mauser SP66

About: K'NEX gun builder here at Instructables. More or less retired from the community, but I still pop in now and again.

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!

    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.
