Internal Specifications Directory

I figured it would be useful to have as much detail on blaster internals as possible all collected into one thread.

Below is a table of info I have collected already as well as a number of other direct plunger blasters I think would be worth having info on. It wouldn't hurt to include the reverse plunger blasters as well down the track.

I was most interested in the plunger volume's as a way to gauge the potential air output from each blaster.

Blaster	Plunger draw length (mm)	Plunger tube ID (mm)	Plunger tube volume (mL)	Spring Length (mm)	Spring OD (mm)	Spring Load (Kg)	Seal Type
Longshot	82	35	78.89	145	30	2.6 (stock)	O-ring
Tripleshot	70 OR 80 (8 clicks)	36.5	73.24 OR 83.70 (8 Clicks)	120	26		Skirt
PAS	90	40	113.1	160	37		O-ring
RFSG	95	33	81.25	137	27		Skirt
Shadowhawk	133	27	76.15	175	18		O-ring
Swarmfire
Stampede	83	24.5	39.13	113	21		O-ring
Nitefinder	45	24	20.357	83	22		O-Ring
Wipeout	60	25	29.45	135	12.5		Skirt
X-Shot Stealth	40	25	18.09				O-ring
SGN-R3L	228	30	161.16	279	27	14	Rubber Washer
SGN-R55L	228	55	541.67	279	27	14	Rubber washer
SGN-PAR55M	152	55	361.11	178		14	Rubber washer
Hyperfire DTB	40	21	13.85	80	18.5		O-ring
Hand Cannon	80	36.5	83.70	135	33	7.5	Skirt

This would be extremely helpfully to most people. Thanks man!

And sticky it shall be.

I've also added some corrections there too.

Loving it. Makes me want to get a PAS

Edit: I also believe the firefly is a direct plunger blaster as well. It might be interesting to see what the volumes of that thing are. It'll probably determine why it can't compare to any other of the direct plunger blasters

I like the looks of this. A lot.

If you're putting two values for the plunger tube volume would it also help to put the tube lengths for both volumes? I know that you can calculate backwards from the volume since you also know the ID, but it would help to clarify things.

Info added for Stampede, Wipeout and Stealth.

While the Stealth has a good sized plunger tube, its measly 40mm draw really let's it down. A draw extension would do wonders here.

Everyone knows the Wipeout has great power. It's capable of 70ft with minimal mods. Goes to show how inefficient the Stampede is in comparison. Its plunger tube is 30% larger but the barrel setup can't make use of the power and limits you to similar range when modded. Makes me even more keen to work on a better breech system for it.

Nice work Oxy

You might want to change the length of the stampede and wipeout springs. You've put them down in centimetres I think.

Stampede and Wipeout spring lengths, only half an inch? Is that the length of the draw, or spring? And either way, I'm sure the draw is longer than that? Lol.

Sweet thread, Oxy!


Edit: Just read Echoes' post again, realised I was just repeating it, sorry. Genuinely didn't understand, wasn't meaning to pick shit at it. Clearly, I have and clearly, I've upset people.

This shits me. Somebody puts a heap of hard work in for the benefit of other's, and all he ends up with is people finding mistakes in his work. I've had it happen a shit-load to myself, and I'm f#cking over it.

Use some courtesy people, how about sending the guy a PM, instead of plastering it all over a thread, and making it look cluttered...

I like your work Oxy, and have the ability to recognise a decimal point in the wrong position, and move on and appreciate the contribution you've made. Thanks mate.

Cheers,

Better than people sitting there quietly and never letting someone know their mistake. I personally like constructive critisism of my work. Public or otherwise.

Well done, I'm sure this will help out a lot of people.

I'm slightly disappointed in the RFSG plunger tube Diameter. My Man'spring may not fit in it.

This is very awesome. I'm going to post this up on CanadianNerfers. Very informative. Credit to you course.

Yeh, I don't mind constructive criticism either - but that's pretty much all you get around here. In the real world, things like this (minor errors/discrepancies) tend to be discussed in private, if you have a decent boss/are a decent boss etc.

It's a genrally accepted criteria for whether you're working with decent people, or clowns.

Cheers,

1st post updated to include the SGN series blaster specs. Yes, I know they are home made's but I think it's worth having them to compare. How crazy is the R55L's volume
I'd also like to include things like the Aussie +bow and the other more popular home made designs.

Does anyone have a BBB and DTB they can measure?

Hey Oxy,

I can do the BBB later on in the week, if that works for you...

Cheers,

Okay, HyperFire DTB:

plunger tube draw length - 40mm
plunger tube ID - 21mm
plunger tube volume - ~13.85 mL
spring length - 80mm
spring OD - 18.5mm
spring load - ?
seal - o-ring
