I didn't think each question needed it's own thread.


My crossbow question: I want to add a [k25] spring in mine and I want to replace the white washer on the plunger head like in splits write up, but I can't cut the fender washer right.
How long will the white washer last with a [k25]. Are there any other alternatives for reinforcing? Does anyone have a pre cut washer I could buy?
I want personal experience for the first answer.


Everything above this line is about a crossbow
--------------[edit] There has been a few confusions, so this should clear it up--------------
Everything below this line is about an Airtech 3000


Dart/barrel fit question: My darts slide perfectly in 17/32 brass, I need a barrel material with a good fit for an airgun, like a 3k. What barrel materials will work for my darts? How expencive and where can I get it.
I've tryed some thickwall petg, but some parts were warped and the only dart I had was crappy.

Thanks in advance for the help.

You definitely need to reinforce the plunger head, the white thing fails even with the stock spring after awhile.

Ok thanks. Have you used splits method of reinforcement? I just can't get the cut right.

I have never modded an xbow, but Atomatron has fixed one that had that problem.

Bump (I guess)
I still would like some answers.

A good air gun fit for a dart that fits well in 17/32 is to take about three inches of 17/32 and nest it in 7 or 8 inches of 9/16. Thats what I use for my homemade and it hits well over a hundred. I also tried using it on my 3K and it works extremely well there, too. The only thing to worry about is if you are using it on a 3K then you need to get some barrel spacers because the heavy brass will cause the barrels to "droop." Its not fun in a war to line up a shot and have it fly 30 feet to the left because your barrels are crooked.

I could basicly get the same affect but with 17/32 in petg right?
While being a shit load cheaper. Then it will be lighter so no drooping! What kind of ranges does your 3k get? And what have you done to it?

Yes, 17/32 in PETG will work just as well. Don't make your barrel 1ft long though. I see a lot of crossbows with that and it's just excessive, and probably hurting ranges. Stick to 8-9 inches.

That is too long, but this is for my 3k.

Using a cut up washer will eventually rip off the tip of your plunger head. I like soothsayers method for replacing the plunger head. It'll last the longest. But if that isn't an option for you, I've found that gluing just the right sized washer to the inside of the white disk will keep the spring for riding up around the plunger head, although I have not war tested it.

I never had any luck with 8-9 inch barrels. I could only get the ranges I wanted with a foot of brass and tightening rings. Crossbows seem to be really picky about barrels so try anything and everything.

I'm going to look into soothslayers style.

Again, the dart fit question isn't about my crossbow. It's about my still barrel less 3k.
