My magazine isn't feeding/working.
This can be a myriad of causes, so let's go through the steps together.
1. Could be the follower and spring - try pushing up on the magazine with your fingers and if you feel the motion is sticky or staggered movement. If so then either the spring may be getting stuck and coiling onto itself, or the magazine follower piece is too large for the tube.
To fix this, remove the magazine spring from the blaster prefereably from the front and see if it has tangled. If so, try reinserting the spring. If you find the spring consistently tangling, try putting it in backwards (flip it around).
Then check the fit on the follower. Take the magazine tube and slide the follower back and forth checking for wide spots where it may bind. If it's getting stuck, then the follower is too large. Reprint or sand down this part until it slides easily. For hardware kit users, these tubes should've been checked by quality assurance for this fit prior to packaging and shipping.
2. The shell latches may not be opening far enough. If the shells are getting stuck specifically at the shell latches, then they may be not be moving far enough. If you purchased the hardware kit, I include these preassembled, but this is mostly just to keep all the parts together. I recommend you print these parts yourself to match with the rest of your build.
If the latches are moving, but just not far enough to let the shells through, you can cut or file the contacts down until they can pass.
My blaster isn't staying primed
If your blaster is firing on its own and can't seem to be catching the prime, then it's highly like that the transfer bar attached to your trigger is too long. The simplest solution is to remove the trigger assembly and sand down the end of the bar that makes contact with the rear sear assembly in the backplate.
Here is comparison of how the old bar looks to the new one. The top is the new shortened bar.
Here is how the bar should look poking out the back of the blaster through the trigger guide.
The magazine follower pops out on the last shell
This can be caused by any combination of the following:
1. The follower is too small and is popping through. Adding tape to the bottom circumference of the follower can help by widening it.
2. The magazine spring is too strong - cut a couple coils off the end to decrease its preload.
3. The shell latche springs are too weak - if the shell latches are not snapping back closed, this means they are getting weaker and need to be replaced. A weak shell latch spring will allow the follower to pass through.
My problem isn't listed
In this case you can do any of the following
1. Diassemble and reassemble the blaster. Sometimes, just doing this solves the problem when other methods fail. I don't know why this works, but it;s like turning the computer off and back on again.
2. Message me on Etsy here: https://www.etsy.com/shop/GDop26
3. Post your issue on facebook and my swarms of members will likely assist you. But remember to be specific about your problem and mention whether you've purchased it assembled, or you are building it yourself: https://www.facebook.com/groups/SpringThunder/
4. Directly message me on facebook, if we haven't met already, then you'll be directed to message requests, which can sometimes take some time for me to notice.
My shells are getting jammed to the side of the ejection port
This will happen to some degree, but should not exceed over 5%. That is a sign that something is wrong. Only make these checks if you are experiencing issues with your blaster.
1. First check the aiming down sight alginment of your blaster. When looking down the "sight", your spring thunder should tilt slightly up and to the right. This check is not the rule, if your blaster is working fine and it is not tilting in this directly, do not make any additional adjustments.
Adjust the tighteness of the 4 rear perimeter screw on your blaster to make this new alignment. Slightl up and to the right usually cures these shell jams.
My bolt/pump is getting stuck on the forward action
1. Try loosening all of the 4 perimeter screws located at the back of the blaster. Generally speaking, a looser blaster operates more smoothly.
2. If you're building your blaster this is likely because you've forgotten to clip the excess spring legs off the ends of your shell carrier. Cut these off and your problem will go away.
3. If you have purchased a premade blaster, then it's possible that the screws holding the action bars/priming bars to the bolt have become loose and are now catching on the ends. To tighten these without taking the blaster apart, you can use the angled slotted holes above where the trigger is to tighten these screws from the outside. Index the bolt using the pump grip to align the screws to be tightened.
My blaster won't prime
This can be a myriad of issues.
1. Check that the screws are tight. Sometimes they come loose during shipping or use. Check "My shells are getting jammed to the side of the ejection port" for instructions on aligning the blaster using the rear nuts.
2. If you have plastic action bars, it may be catching on the left action bar's shell latch. You can check by looking into the ejection port and seeing if it's getting caught. If so, you can either request a new one, or take a file and make its chamfer angle less steep.
In either case, you'll have to disassemble the blaster to remove and replace this action bar.
3. Disassemble and reassemble the blaster without its rear thick power spring, and see if you can get the blaster to catch. Also tighten any interior screws if you can.
My shells are getting stuck in the chamber
1. First easy bit, if you place the shells directly into the chamber by hand, this will jam the blaster. To load a single shell, you need to just drop the shell into the port. The lifter mechanism will raise the shell to be chambered as you pump the bolt forward.
2. When firing, be sure that your bolt is fully chambered forwards. If there is a gap and the bolt isn't completely forward when you fire, you risk damaging the blaster and jamming a shell into the chamber.
3. Check to see if you have a broken extractor. That is the little hook that pulls the shells out. If this is broken, you won't be able to automatically extract shells.
My blaster is firing weakly
1. Check that you are fully chambering your shells before firing. Then be sure that you are holding your bolt shut, not doing so can both damamge your blaster (and/or shells) and keep you from reaching your blaster's full potential.
2. Check your dart fits. Sometimes darts depending on their quality and brands, may not fit into the shells well. Too tight, and they may not come out well, if at all.
3. If the blaster was disassembled or been sitting idle for too long, the lube may have dried out. Disassemble your blaster and add more lube to the piston/plunger tube assembly. You can see which parts these are by referring to the assembly guide here: https://www.shellingtonblasters.com/assembly-guide
My blaster isn't ejecting well or at all
1. Check your extractor. If your extractor is broken or loose, then it will not eject well because your shells are being held too loosely.
2. Remove the power spring first and then check your spring tension on the ejector. If it feels weak, then your springs have become too weak. Remove the ejector and check to see the spring's angle. It should form a 90 degree bend or smaller. If it's more than this, then bend it until it is 90 degrees or less at rest and reinstall.
