Nihil: We are at somewhat of a misunderstanding. I'm arguing tha a completely bored out recon/raider will perform better than a deadspace removed one limited to ~1/4" size hole of flow. You're arguing that a deadspaced removed recon performs better than one that has more deadspace, but is still limited to the same size hole, and thus flow. Both of our arguments are correct.

Ok, I now see what you are saying with the message. Yeah, these guns were all limited to 1/4" air holes because they were to be used more for indoors and just being loaner guns in very friendly games that don't need excess power.

Which your comment is making me think about looking into another setup to test with this using 1/2 inch aluminum tubing (13/32" ID) I accidentally ordered a couple months ago and had no use for... and another reverse plunger gun I have (I somehow have a lot of RP setup guns lately, thanks to Nerf) that has a 3/8" airflow hole and seeing if that's a help or hinderance to it as well. So when the weather does clear up I will test these.

@Moosa: Thanks.

But Is the other raider bored out completely?

I decided to also test this in a raider (since I have two raiders I use as guest blasters with identical mods done to them (Basic AR removal, spacer to fully compress spring and increased plunger seals) I decided to put this in the one that tends to be the weaker of the two and tested them side by side

I'm not sure if I'm understanding your question... I used two raiders with the exact same modifications done on each except one I put this filler in to see if it would make a difference. Which it did seem to help in both velocity and trajectory.

Of course the deadspace removed one will perform better if flow is identical between the two.

That's the point of this mod. I'm not sure if I'm misunderstanding something in your post?

The idea behind this was to create an easy (it literally takes 15 seconds to hand drill through a piece of fbr), cheap (less than a dime for items used) and removable setup if it failed so I didn't want to use hot glue or anything that could be difficult to revert back to stock form. Because yes, I kind of expected it to fail but with the testing I have done it's only seemed positive for me.

This was also basically meant for stock barrels only. As usually, due to the loose dart fit, the dart is already out of the barrel before the full back pressure can get to it, resulting in just wasted air volume as opposed to an upgraded barrel setup where the blaster actually builds up the full pressure before the dart is pushed out of the barrel. This should give a stronger initial burst which, I would think, would give the dart a better range than a standard setup where most of the pressure is wasted anyways.

I decided to also test this in a raider (since I have two raiders I use as guest blasters with identical mods done to them (Basic AR removal, spacer to fully compress spring and increased plunger seals) I decided to put this in the one that tends to be the weaker of the two and tested them side by side in my house (distance wall to wall is limited to only 25 feet but unfortunately it's winter here with really bad winds so attempting to go outside would be useless). The raider that I did this too is now outfiring the one that seemed stronger before by a noticeable difference in the velocity the dart travelled at and the relative straightness of it's trajectory (using stefans, not streamlines) So I will have to wait until the weather breaks so I can actually test ranges outside to confirm for myself and I will use the same gun for both tests since this can be removed cleanly. And if, when I test it outside, it fails miserably I'll let you know.

nice, I'm getting a longstrike soon so, i was wondering what size fbr you used? 1/2 inch?

You will need to find a FBR that fits as tightly as you can twist into the reverse plunger.

Items needed:
- Reverse Plunger System
- Foam Backer Rod (FBR) (Either thicker 1/2 inch or 3/4 inch cheap Home Depot/ Lowes foam)

As far as the foam I'm using... it's a 1/2 inch foam that can actually fit snugly in 1/2 inch PVC and barely fits in PETG and was incredibly difficult to twist into the back of the reverse plunger

Straw modding doesn't help guns with recon internals. Flow > deadspace in these.

That was an argument I've heard before and why I wanted to do something that could be reverted back to stock if I failed when testing it... but from test firing it, it's added noticeably to the speed of my darts and the rebound they are getting once they hit. So, unless for some reason my Longstrike is the exception to the rule, this may actually work.

And for those that will ask, I haven't range tested it outside, it's winter in Ohio and I don't feel like going outside.
