  Yoko Ritona's Sniper Rifle
I was commissioned to make Yoko Ritona's sniper rifle from the anime "Tengen Toppa Gurren-Lagann".

The pistol grip was cut from 1/2" MDF.

I cut the trigger from styrene and made the pivot from a nail.

I used small torsion springs to force the trigger to the forward position. Styrene was used to line the interior of the trigger cavity and poplar was used to make the trigger guard.

The muzzle block started as a 2" x 2" block of poplar.

I cut the angles on the table saw.

I threw it on the lathe and shaped the end.

I drilled 3/8" holes on each side for vents and drilled a 1/2" hole in the end of the muzzle.

The magazine sides were made from 1/4" MDF. I cut decorative slots in the sides with the table saw.

The complete magazine boxes.

MDF forms the box that holds the magazine.

I formed the magazine release by hammering aluminum sheet around a steel bar.

The shaped release lever, pivot pin and slots cut into the grip.

The release in place. A small compression spring keeps in pressed forward.

The body of the rifle is a 35" long piece of 1-1/2" PVC pipe. The rings at the rear sling loop and bipod were formed by cutting sections from a PVC connector.

The butt was made from a sheet of 1/4" MDF sandwiched by 3/4" MDF. I sanded the interior curve to meet the PVC body.

I drilled through the top of the PVC so I could access interior screws to hold the butt in place.

For the bolt slot, I drilled two holes and then cut between them, removing a section of the PVC.

I inserted a 1-1/4" PVC pipe into the 1-1/2" PVC body to form the bolt. For the handle, I used a socket screw and a bit of brass tubing to cover the exposed threads.

The assembled body so far.

To cover seams and make the butt more solid, I wrapped it with .04 styrene plastic.

I glued on some styrene strips along the edge. The bolt insert was capped off by a styrene plate.

The sight rail was glued and screwed on the top of the body tube, conveniently hiding the holes for attaching the grip assembly.

I found an inexpensive folding bipod at the Sports Authority but had to cut of a bit so it would fold up.

I used the supplied screws but attached the bipod from inside the barrel, through two access holes I drilled above them.

For the feet, I cut a square of steel and epoxied them to the legs.

I cut panels from sheet aluminum and attached them with pop rivets to the legs.

The completed bipod.

The bipod folded up.

For the barrel I used a 1" oak dowel. The fit wasn't tight so I used a section of PVC to act as a spacer. The slot at the bottom allows it to pass by the bipod screws.

Once inserted, it's held in place by two screws that use the bipod access holes.

I bought a set of sling mounts that screw into the PVC rings on the body and the barrel.

The scope was made from PVC (front and rear sections), wooden dowel, lathed wooden cones and MDF end caps.

I was able to get lenses the perfect size from a Dollar Store insect viewer. The front lens was the unmodified "viewing" lens and the rear lens was made from the enclosed magnifying glass.

The sight adjustment knobs were cut from a 1" dowel.

I cut posts from brass tubing that will also hide the knob attaching screw.

The final knobs.

I cut the front and rear scope mount out of 1/4" poplar.

I cut each in half and inserted long bolts to attach them. The bottom bolt goes through the rail.

The final assembled rifle with a coat of primer (per client's request).

The rifle is a massive 73" long!

Detail of the scope. I forgot to add the lens on the small range finder.

The folded bipod with added rubber feet.

The magazine is an open box so you have someplace to hide your and ID.
Hi friend.

I have been following your site for some time, and I must say you sure do some phenominal work! I too have a prop blog at Its only been up and running for a few days now so I don't really have anything posted. Im fairly new in the prop world, but have browsed and posted on The Dented Helmet as well as the BBC for a couple years. But in any case, keep up the great work!

Amazing work!
I've been a fan for some time.
I check in now and then to hear my jaw hit the floor.
Very inspiring. Thank you for this blog and keep up the good work!
Perfect!! Thanks a lot for help a poor girl from brazil who was trying to make this rifle =^^=
you're amazing.
WOW. Wow wow wow, is all I can say. I'm surprised this doesn't have more comments. Your work is amazing!

These are all the dumb things I find myself obsessed with building when I SHOULD be doing something more productive.

As a kid I built lots of plastic model kits, never knowing that one day those skills would actually be of use.
