The NERF Sharp shot has to be one of the most disappointing stock blasters I've ever purchased. Stock, this gun was hitting abysmal 5 to 9 feet flat, and for it's size, that's just unacceptable. Time to make this into something worth saving from the dumpster.

Supplies

--Sharpshot

--3 inches of 17/32 Brass

--Replacment Spring (I used a Nite Finder, not optimal, but it's what I had on hand)

--Nite Finder O-Ring (Or the equivalent)

--Hot Glue

--Dremel With Fine Grit Sanding Drum

--Silicpn Grease

--Silicon Sealent (OPTIONAL)

--Piece of Plastic Tubing That Fits Securely Over Brass (OPTIONAL)


Start by unscrewing your blaster:

Remove these side panels:

Posted Image

Internals:

Posted Image

Get your replacement spring. Stock spring is on the right, Nitefinder is on left. Set it aside for now.

Posted Image

If you don't have a replacement spring, putting a few nickels behind the stock spring will give it a boost

Posted Image

If your replacement spring is pretty powerful, consider replacing the catch.

Posted Image

Pull the plunger assembly out. Slip your NF o-ring on with the stock ring.

Posted Image

Drill out the AR. I don't have a picture of it before, but I'm sure you can figure it out

Posted Image

Time to do the barrel replacement. Cut your 3 inches of brass.

Posted Image

Smear a bit of hot glue on the brass, and nest it inside the stock barrel.

Posted Image

The stock orange tips opening is to narrow for the brass to fit through. Using your Dremel, sand the opening until the brass fits snugly inside.

Posted Image

Pad the plunger head. I suggest this writeup (hint hint nudge nudge): http://nerfhaven.com...showtopic=22201

Posted Image

Now lube that sucker up, and youre ready to resemble.

Posted Image

Internals before reassembly.

Posted Image

(Nearly) Finished Product.

Posted Image

I didn't like the way the brass was exposed, so I found a small section of plastic tube,

Posted Image

And glued it on over the brass.

Posted Image


All done!

Ranges: Suprising. 50 to 60 feet. A nice improvement over stock ranges.

UPDATE: did some testing, and found out that it vacuum loads darts. How about that?


Questions? Comments? Flames?

You may want to just use e-tape until the brass fits in that plastic, and then place it on. Instead of that mound of hot glue.

If two powerful is a problem then just go with one powerful. I guess this style of hopper will work even beyond three powerful..

Are you sure that is a Nightfinder spring? In my modding of this gun, a maverick spring barely fit. Also, that is not a Nightfinder o-ring, it is a maverick o-ring.
Anyways, nice mod. :)

Maverick springs are actually smaller than an NF spring. And now that I think about it, it might actually be a maverick o-ring.

The Sharp Shot is the most abysmal performer I have amongst my Nerf blasters. I cannot help but chuckle when the darts start to fall right out of the barrel. The size and decent ergonomics are a plus for me though.

Interesting take on it, and very nice ranges. Nice illustrative pics too. I would smooth & port the plunger a bit more for added airflow.

I also suggest re-enforcing the wall that is just before the catch. When I added a heavy spring to one I did for a friend, the wall broke. He fixed that problem by running a bolt though the blaster. Not the cleanest, but it was effective at what It did.

I would suggest using epoxy puddy though, before it breaks.

If this is using only a NF spring, you may just want to add a stronger aftermarket spring. Don't go crazy though, this is still a reverse plunger.

Even if you don't upgrade the spring further, it is a good idea to carry out some of the aforementioned reinforcements, pad the plunger, and add epoxy putty in the area of the shell behind the spring to prevent deformation of the plastic.

All great ideas. I will update the writeup as soon as I can.

If you have patience and a square needle file, you can nest your 17/32 brass inside the barrel. This way you don't have that chunk of brass sticking out and you don't have to alter the orange front piece.
Posted Image
There's a little over 2.5 inches in there, gooped and waiting to be cut.
I just filed out the inside while turning the barrel in my other hand. It would have been easier if I had some sort of really long sanding attachment for my Dremel. If I ever do this again I might try gluing some sandpaper to a dowel.

I did nest the brass in the stock barrel; I just made my brass longer than the stock one. I don't see your point.

You used 3" of brass and you have what appears to be 1"-1.5" on the outside of the blaster. I used a little over 2.5" of brass and all of it is inside the stock barrel. Since the brass is inside the barrel I don't have to alter the front piece or worry about exposed metal.

Also you never said how you got the brass into the barrel in the first place. 1/2 brass will fit, but 17/32 is just a bit too big. I eventually figured out that you cut your brass with rotary pipe cutters, which tapered one end and allowed it to slide inside( you can see the tapering at the top of pic. 9). This information is important; I thought I was using the wrong size of brass at first, because mine wouldn't fit

Exactly, a NF spring would never fit. You can tell from the picture that it's a maverick spring, a NF spring's coils are much closer together.

I noticed you didn't reinforce the bolt lock. When I added new springs to mine, after about 50 shots the plastic just bent away to a point where the spring wouldn't lock back anymore.

ended up having to fit some 1/8" thick aluminum L brackets with some JB cold weld.

This may be a dumb question but how does the brass improve performance?

Have to agree with this. I always liked the shell design of this blaster.
