Nerf N-Strike Jolt (Blue Version) - Internals Guide!

This guide will serve as a reference for the internals of the Nerf N-Strike Jolt (Blue Version).

For a review of the Nerf N-Strike Jolt, click Here.

Nerf N-Strike Jolt (Blue Version) - Plunger Tube Internals


Note:

- To disassemble the  plunger parts, just use a flat head screwdriver to pry and separate the metal rivet piece from the plunger head and rubber padding, then use a pair of pliers to twist the metal rivet piece off the plunger rod.

 - To replace it back, just reverse the process (make sure the rubber padding is positioned back properly). Twist the metal rivet back into position. At the final point, just use a hammer to tap it back into place.

Nerf N-Strike Elite Clip - Mod Guide!

So you have got your new Elite clips, filled them with ammo and loaded them into your blasters. Ready for Nerf games!

But wait! Notice the clear part of the clip is facing the right side?

Its fine for left-handed users... but for right-handed users it means they cannot see how much ammo is in the clip, instead all their opponents can see the ammo count clearly!

Here is an example of the Elite 18-dart clip in a Longshot:


Right-handed users cannot see their ammo count...


...but their opponents can see it clearly!

Studies suggest that up to 80-90% of the world population is right-handed, which means alot of users (like me!) will have this common issue with their Elite clips.

So here is how to solve it, with some simple modding steps.

Step 1:

Cut or sand down the raised clip restriction areas at the top part of the clip.

Original clip (left) vs modded clip (right).


Make sure the raised areas are flattened and smooth.


Step 2:

Use a dremel or hobby knife to cut a clip-lock notch on the side of the clip. Mirror the exact notch position from the other side.


Ensure that the new clip-lock notch is cut at the correct position.


Final Step:

Clean up the notch cuts and test load it into blasters. Its done!

Original Elite 18-dart clip (left) vs Modded Elite 18-dart clip (right).



:: Results ::

Here is the modded Elite 18-dart clip loaded into a Longshot.


Right-handed users can now see their ammo count...


...but their opponents cannot! :)

Enjoy your improved Elite Clips!

Note: This mod can be done on any N-Strike clips or drum magazines too.

--

Additional Note:

For blasters like the Nerf Retaliator or Recon, the modded clips will get blocked by the casing part in front of the clip well (as shown below).


Therefore you'll need to also cut off the raised section on the clip, then it can fit into those particular blasters.


- Update! -

For blasters like the Nerf Stampede or Rayven, their clip detection pressure switches are in a position that will be affected by the unused notch, hence the system will "think" that there is no clip loaded. (Thanks to harpuia for this tip!)

Therefore modders will have to either tape down or bypass those pressure switches, or just use tape to seal the unused notch.

Nerf N-Strike Elite Retaliator - Mod Guide!

This Mod Guide will cover performance mods for the Nerf Retaliator.

Mods covered:
- Air Restrictor (AR) Removal
- Spring Replacement
- Locks Removal

Note: These mods are also applicable to the Nerf Rampage as they both share similar internal bolt and plunger mechanisms.

Disclaimer: Modify at your own risk. Modifications may wear out or damage your blaster. Please be careful when using hobby tools!


:: AR Removal ::

Step 1: Disassemble your Retaliator. Make sure to remove all the screws before detaching the casing.



Step 2: Take out the bolt sled assembly. Disassemble the plunger mechanism components and remove the plunger casing from the bolt system.


This is what the bolt looks like with the air restrictors still intact.



Step 3: Use a long screwdriver and a hammer, carefully knock out the air restrictor assembly though the back of the bolt.


You can also use other tools (ie. power drills) to remove the air restrictors too. Just be careful not to damage the bolt in the process.

This is what the bolt looks like with the air restrictors removed.


At this point in the process, you will probably notice that a leftover part of the air restrictor (the 3 pronged piece) is still inside the bolt, and it will tend to rattle loosely back and forth. Simply apply a drop of glue inside the rear section of the bolt and let that loose piece adhere to the back so that it doesn't move anymore.


:: Spring Replacement ::

One of the ways to increase the speed of air delivery through the bolt is to replace the stock spring with a stronger aftermarket spring.

There are many different springs with different sizes and spring force ratings. Spring choice will depend on your usage.

This example below shows a stock spring (top photo) vs. an aftermarket 8kg load spring (bottom photo).


Notice that the stronger aftermarket spring i use is made shorter than the stock spring, this is because the spring wire is thicker, hence it takes up more space when compressed.

The reduction in spring length allows the plunger system to accommodate the extra space required by the aftermarket spring (or else the plunger will not be able to catch properly).

Note that when using shorter aftermarket springs, the bolt lock should also be removed to ensure that the bolt does not get stuck during usage (see below for more information on bolt lock removal).

Here is what they look like installed within the plunger system.


Note that in this plunger design, the spring has to be kept within the catch system dimensions to work.


:: Special Notes ::

Generally for blasters with air restrictors removed, padding is usually recommended to be installed on the plunger. This is because without the AR, there is no air buffering system to cushion the plunger on bolt impact.

But in the Retaliator plunger system, the plunger itself features a narrowed internal area at the front section, this creates a sort of "buffer" effect and prevents the plunger from striking the bolt.


During modding tests, it turns out that plunger padding wasn't necessary in this blaster. Even without any plunger padding, when the blaster was fired, there was only a muffled impact sound (instead of the loud cracking noise common in previous blaster designs).

In addition, the stock o-ring  already has an excellent seal, so there was no need to replace it. Note that if the plunger seal is too tight, it may create excessive resistance and slow down the plunger, resulting in noticeably reduced performance.


:: Locks Removal ::

Remove the bolt and trigger locks. This is an optional modding step, but it is highly recommended (especially in blasters with air restrictors removed and using shorter aftermarket springs).


With the locks removed, it allows users to be able to release a primed blaster in a controlled manner. This is more convenient than having to fire an extra shot just to de-prime the blaster and helps prevent dry firing.

The user can simply push back the bolt anytime, pull the trigger to release the catch, then ease the plunger forward under support with the priming grip.

In addition, as mentioned earlier, the bolt lock removal mod is also required when using shorter aftermarket springs, to ensure that the bolt does not get stuck during usage.

Important Note: With the bolt and trigger locks removed, users have to ensure that the bolt sled is pushed all the way forward before firing (do not fire when the breech is partially or fully open).

For additional reference, here is the bolt lock removal procedure for the Nerf Rampage (photo shows the left side of the Rampage casing):



:: Final Step ::

Assemble everything back together and its all done!



:: Modified Nerf N-Strike Elite Retaliator - Range Test Video ::




:: Sample Test Fire Data ::

PTG: Parallel-To-Ground (Shoulder height, no elevation)
ATG: Angled-To-Ground (Aimed higher, 30 degrees elevation)

Distance is measured at where the dart lands (Average of 6 darts).

Stock Elite Retaliator
Ammo: Elite foam darts
PTG = 45-55ft
ATG = 65-75ft

Modified Elite Retaliator (AR Removed Only)
Ammo: Customized foam darts + 1.0 gram soft silicone tip weight
PTG = 55-65ft
ATG = 75-85ft

Modified Elite Retaliator (AR Removed + 8kg Load Spring)
Ammo: Customized foam darts + 1.0 gram soft silicone tip weight
PTG = 70-80ft
ATG = 90-100ft

Note that Elite foam darts can achieve similar ranges too, but their overall performance and accuracy tend to be rather erratic when used in modded blasters (ie. they still curve and swerve in flight), so their results are less consistent.

The tests were done under controlled conditions and the results are sample estimates for reference (your results may differ depending on materials and mod techniques used).


:: Additional Notes ::

For modding reference, i've also tested the brass breech mod on one of my other Retaliator units and its ranges improved further by another 10-15ft. 

Note that although an improved breech system with 100% air seal does help increase power efficiency and range, the overall performance improvements are still based on their existing plunger air volumes (compared to larger direct plunger blasters like Longshots or Stampedes).

Elite Foam Darts - Comparison & Internals Guide!

This guide will look at the differences between the new Elite foam darts and the older Streamline foam darts.

Weight comparison between both foam darts:


The Elite foam dart is noticeably lighter at 1.0 grams, while the Streamline foam dart weighs in at a heavier 1.3 grams.

Here is a cross-section comparison of both foam darts:


The Elite foam darts have a much shorter tip stem, which is lighter and shifts the tip weight further forward within the foam dart. This helps it to achieve better balance and improved range.

Nerf Dart Tag Snapfire 8 - Mod Guide!

This Mod Guide will cover some basic performance mods for the Nerf Snapfire 8.

Mods covered:
- Air Restrictor (AR) Removal
- Rotating Barrel Dart Post Removal

Note: The modding steps are similar to the Nerf Speedswarm Mod and Nerf Swarmfire Mod.

Disclaimer: Modify at your own risk. Modifications may wear out or damage your blaster. Please be careful when using hobby tools!


:: AR Removal ::

Step 1: Disassemble your Snapfire 8. Make sure to remove all the screws before detaching the casing layers. Remove the plunger tube.


Step 2: Look down the plunger tube, you will see the air restrictor assembly.


Step 3: Use a wire cutter and snip off the 4 support posts holding the air restrictor assembly, all the AR parts will fall out.


The ARs have been removed! Easy.


:: Rotating Barrel Dart Post Removal ::

This mod is for users who want to be able to use solid core or short length DIY foam darts (ie. stefans) or as a modding step before re-barrel mods.

Detach the rotating barrel from the casing.


Use a wire cutter to remove the dart posts.


Clean up all the debris and sharp edges, make sure the back of the turret is smooth and flat.


I've found the existing turret barrel fit and length ideal for the 3.25cm length customized stefans that i use.


Assemble everything... now you have a stefan compatible Snapfire 8!


With the stefans sitting inside the turret barrels, nothing is protruding out of the front, therefore its much easier to store or holster the Snapfire 8 in this configuration too. :)


:: Modified Nerf Snapfire 8 - Range Test Video ::




:: Sample Test Fire Data ::

PTG: Parallel-To-Ground (Shoulder height, no elevation)
Distance is measured at where the shot lands (Average of 8 shots).

Modded Snapfire 8 (AR Removal & Dart Post Removal)
Ammo: Customized foam + 1.1 gram soft silicone tip weight

"Speed" Mode Range = 35-40ft
"Power" Mode Range = 45-50ft

Note that the tests were done under controlled conditions with customized foam darts. The results are sample estimates for reference (your results may differ depending on materials and mod techniques used).


:: Side Notes ::

Additional plunger to turret seal improvements were not required as the Snapfire 8 uses a system that pushes the plunger against the turret during the firing process, thereby already creating an excellent turret seal.

In addition, i've not done any stronger aftermarket spring installations as i'm focusing on retaining the blaster's rate-of-fire and ease of use... and my trigger finger doesn't exactly have superhuman strength yet! :)

Nerf Elite Rampage Internals - Quick Preview!

With the Nerf N-Strike Elite Series rapidly building keen interest amongst the Nerf community, many enthusiasts have also been curious...

How did Nerf improve the spring powered Elite blaster models? Did they retain the reverse plunger system or did they re-design it with another type of plunger system?

Here is your answer!


Yes... Direct Plunger System!

Note that the units i've had a look at might be different from the final production versions. Therefore, this not a full review on them yet, just a preliminary insight into the new internal design.

This photo shows the plunger rod in the primed position (with the spring removed).


Plunger rod, spring and catch removed from the casing. The plunger catch point is situated just behind the plunger head.


Here is a view of the plunger system from the back in un-primed position (left side in the photo) and without the plunger rod (right side in the photo). The bolt which pushes back the plunger head and rod during the priming action can be seen at the front of the plunger tube (similar to how a Nerf Longshot works).


Spring plunger design comparison between the Nerf Raider reverse plunger system (top in the photo) versus the Elite direct plunger system (bottom in the photo).


Spring plunger size comparison between the Nerf Longshot direct plunger system (top in the photo) versus the Elite direct plunger system (bottom in the photo).


Kudos to Nerf for listening to their fans and improving the designs on their new blaster models, they have done an excellent job.

The new Nerf N-Strike Elite Series is indeed shaping up to become a hot favorite amongst Nerf enthusiasts! :)
