Aluminum Longshot Internals!

NerfSG Forum modder Zinv recently got a full set of aluminum Longshot internals custom fabricated and i had an opportunity to check out the setup...


The entire boltsled is made of one solid piece of precision machined aluminum.


Aluminum catch plate.


Full aluminum plunger head, plunger rod and plunger end-cap.


The aluminum parts are strong, yet lightweight... ideal replacement parts for modded Longshots.

For more information, contact Zinv at the NerfSG Forum.

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! :)
