Hop Up Bucking for Airsoft Guns

I got a sig 552 commando airsoft gun by birthday and it worked good for about a month or so and then when i went to use it again it just made a screeching noise, I tried to fix it in every way shape or form i could think of but nothing made this thing fire, can anyone help me?
Experienced athletes share their insights in answering this question:
I have a sig 552 as well and had similar problems but if you take it apart the trigger box will come out and you just need to mess with that a little bit

How to Identify and Resolve Common Issues ?

We offer a diverse range of insights on identifying and resolving common problems in sports. Our sources encompass academic articles, blog posts, and personal essays shared by seasoned athletes. :

There may be a number of reasons why your airsoft gun won`t shoot. This can range from simple wiring issues to more complicated ones like broken teeth gears. While some of these can be fixed, some might require changing parts and a visit with a local airsoft technician.
If your battery is dead and will not take a charge you will most likely need to replace it. Check the fuse. Many AEGs have a fuse, if the fuse goes out the gun will not function. Check the motor wire connections.
This is a fairly common problem with AK-variant guns. The problem is typically either the selector switch (lever) is loose and needs to be tightened or the selector gear is not properly engaging the gearbox and selector plate. Try tightening your selector switch.
Most of the sound comes from the electric motor spinning the 3 cogs in the gearbox. The thump is heard when the piston hits the cylinder head. AEG motors can have different sounds as they come in a variety of shapes and power outputs.
Misfire. This occurs when the trigger is pulled and the firearm does not fire. It is caused either by a weak firing pin or a defective primer that fails to ignite the powder charge. If you are using a blackpowder firearm, inspect the priming cap or charge.
Just as you remove BBs from your airsoft when not using it, you should also remove the CO2 cartridge. Thanks to this, the seals in the airsoft gun will last longer. You should also remember to clean the airsoft gun regularly and properly maintain the seals.
Shots Per Battery

If you are using a 1,400 mAH battery, for example, you can expect to fire about 1,400 rounds before your battery goes dead. That may sound like quite a lot, but keep in mind that many airsoft battles often last several hours.

An airsoft fuse is the first, and probably most effective, piece of protection standing between your AEG and electrical damage. The fuse is part of your gearbox`s overall circuit. An AEG fuse stops too much current flowing around your circuitry should a power surge occur by `breaking`, or halting.
For pistols, it is much more normal to see the 150 to 200 FPS range. While for assault rifles, ones below an FPS of 250 are generally not effective. A good FPS for an assault rifle would be anywhere from 300 to 400 FPS. Anything beyond 500 FPS is generally disallowed in most airsoft events due to safety concerns.
Each gas air gun is powered by expanding gases.

Part of those gases is used by the Blow Back system, which causes the bolt to recoil by means of the bolt`s valves. With each shot, the gas is expelled from the container to the barrel, and then to the piston in the airsoft gun slide, causing recoil.

A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing.
A small . 22-caliber rifle can produce noise around 140 dB, while big-bore rifles and pistols can produce sound over 175 dB. Firing guns in a place where sounds can reverberate, or bounce off walls and other structures, can make noises louder and increase the risk of hearing loss.
For example, if you drop your cartridge near a steel object and it lands at the perfect angle with enough force, the bullet could go off. When there`s enough force, the impact on the primer would mimic the impact of a firing pin after the trigger of a gun is pulled.
It could, but very unlikely unless it lands on something with enough protrusion and with enough inertia to fracture the primer compound against the anvil in the same fashion as a firing pin would, again, not likely, but possible.
In a structure fire, the heat produced during the burn activates and causes the bullets to explode; the larger the caliber of the bullet, the more explosive potential.
CO2 is going to kick harder, shoot faster, and work better in colder temperatures. Due to it`s higher pressure, a CO2 powered pistol will kick much harder than a green gas weapon. Also due to the pressure, most CO2 pistols will have a higher FPS than their Green Gas counterparts.
So is an Airsoft replica safe for your 13 year old? Yes, an Airsoft replica is safe and is not a BB gun. Airsoft is safe for teenagers as long as they`ve been taught about handling and safety. As a parent you need to judge your kid`s responsibility level as well as their ability to follow rules and instructions.
What`s the Risk? Those who do not wear eye protection are at risk of eye injury, according to the AAP. Airsoft pellets that strike the eye can cause scratches, painful pooling of blood inside the eye, lens dislocation or blindness. The AAP recommends that kids use paintball-style protective eyewear.
Though technically airsoft guns are not firearms, so in theory, any age is suitable to play airsoft. To play at an airsoft field the recommended age is 12.
One of the great attractions of airsoft to many players is the realism aspect of it, unlike videogames and movies, airsoft is a fully physical experience where players can see, hold and shoot a physical replica gun at targets and other players in a safe and fun environment.
Samuel Colt developed the first mass-produced, multi-shot, revolving firearms.
Airsoft guns use BBs or round airsoft pellets usually made out of plastic and colored white. Of course, you can find them in different colors and weights, but the standard size is 6mm in diameter. There are some selective models that use 8mm, but most guns are good with the 6mm pellet.
Typically made of plastic, they usually measure around 6 mm (0.24 in) in diameter (though selective models use 8 mm), and weigh 0.20–0.40 g (3.1–6.2 gr), with the most common weights being 0.20 g and 0.25 g, while 0.28 g, 0.30 g, 0.32g and 0.40g BBs are also commonplace.
DMR (Designated Marksman Rifle): 401-450fps, or 1.78 joules max, with a 50` minimum engagement distance, and set to semi-automatic only. SNIPER: Bolt action and a few semi-automatics allowed (i. e. SVD). Velocity not to exceed 500fps, or 2.31 joules max, with a 100` minimum engagement distance.

I bought a new mossberg 590 a1 shot gun a month ago, I love the gun but its having a couple of problems, the first problem is that when shooting every once in a while i get sprayed in the face with exuast from shooting through the safety very scary! any ideas whats causing this? how to fix it? second is that some times the fireing pin sticks and the gun will not discharge a round? the third problem is that i have had feeding issues with gun where it will not realice a gound from the tube, ive taken a tip of a knife to the stuck round in the tube and it prys out with little effort, these problems dont happen every time i go shooting, just every once in a while, but they a happening more and more, im conserned cause the gun is brand new, and i wanna be safe while shooting, can you guys help me? any ideas/solutions? please help!!!!!!!
ANSWER : Personally, with that many problems, I’d call Mossberg and get a return authorization. None of these things should be happening, especially with a new gun.

I just purchased a SIG 552 Commando Airsoft rifle and after about 35 minutes of use, it stopped firing anything. Battery is fine, just doesn’t seem to be picking up the BBs or possibly jamming, but can’t get anything out of it. What could be causing this?
ANSWER : Alright another winding mag issue. On the bottom of your mag there is a wheel, wind it until you meet resistance or you hear double clicks, this will tell you when your done. After fire a certain amount of bb’s it will need to be rewound.

I have a tippmann custom pro with a cyclone feeder. I recently got the SAW stock to put on it and encountered some problems many times after I reassembled the gun. I took it apart at least 5 times before I thought it was fixed but now ive encountered another problem. I believe it has to do with the cyclone feeder not responding or something is out of line in the gun. When I picked up the gun to shoot, no paint came out so I took off the CO2 and the barrel and saw that the paintball was 1/3 inside the gun. I also have a problem when im shooting it sometimes does really fast burst. Thank you
ANSWER : Hi there. Tippmann markers are super tough to make sure that they are put back together properly. The stupid clamshell design plus all the little, under engineered parts make it difficult to get it back together properly, especially after installing a stock. I was in the paintball industry for 10 years but have been out of it for a little bit, but i was one of the founding members of Uprising Nation and was a gunsmith/ salesman for PaintballOnline.com / Xtremes. Now with that said…I even had trouble with the tippmann 98’s…and I can rebuild an autococker with my eyes closed but can sometimes be stumped by the tippy’s bad design. It is really tough to diagnose an issue on these guns without looking at it. You may have the ball detent backwards,l missing a pin, sometimes the after market stocks on those are a little too large on the outside diameter preventing the internals from properly seating. The cycloce system may be off due to the valves not meing properly aligned or the connecting rod not being in all the way. Many times though it is incorrect installation of the detent or the deternt gets damages. That little orange peice of **** flap is a mance. I would start there.

It may seem like i am bashing your gun. Im not… Once they are put together properly they work great. Just DONT TAKE THEM APART. lol. If you buy the parts at a local gun shop they will install them for free.

lol I have 6 guns for sale 🙂

Have a good day

My gun just beeps when i pull the trigger even when hooked up to hpa.battery is new.last time i used the gun just before it messed up i had it hooked to o2 and it would fire then beep ,i have a anti syphon tube installed to. the air shot out the asa instead of the reg when i took off the tank.usually gun holds air with tank off then you shoot it to get rid of stored air,this time it shot out the asa????
ANSWER : You have probably messed up your solenoid, did you fire the marker straight up with the o2? I would make sure that all of the board settings are back to factory default especially the dwell and reattempt with compressed air. If the marker is still not firing get your hands on a new solenoid for it.

Paintballs will fall out of the barrel of my tippmann 98 custom, randomly when the gun is not being fired. I am not sure how to fix this, or if it can be fixed. Mechanically the gun fires and aims great. This is the only problem i have encountered. Pleast help.
ANSWER : Get another ball detente from ebay, this one is the cheapest one I could find.http://cgi.ebay.com/NEW-TIPPMANN-C-98-BALL-DETENT-A5-BALL-DETENT-/370469346400?pt=LH_DefaultDomain_0&hash=item5641b19c60

My magazine for my m10 swat aeg airsoft gun is loaded but i cant get the pellets to feed into the gun without tipping the gun upside down. how can i fix this?
ANSWER : It could be the fact that it is a winding mag, wind the wheel on the bottom until resistance or double clicks are heard, then you are ready to go, eventually you will have to wind it some more though
