If the problem is not the spring, it will be hard for any user to find the faulty part. Possible ReasonsĪ weak or faulty return spring is the primary reason for the trigger reset problem.Īlso, one or two components in the trigger mechanism can become faulty causing the trigger to stick in one place. It can be very dangerous in emergency situations. In some cases, the PC Carbine’s trigger gets stuck and doesn’t reset. Lastly, clean the gun on a regular basis. Maintaining proper grip and avoiding limp wristing are two possible solutions to the problem. Hence, it may not cause any problems during the extraction. Then, rack the slide, and assess downrange which will ensure proper ammo loading. The Fixįor a simple and quicker solution, you can try tapping the bottom of the magazine so that it sits properly. When the magazine doesn’t sit properly, it can cause stovepiping. It is very common among semi-automatic firearms. Some may indicate the problem as the result of using a Glock magazine.īut it is not true because I have seen some users facing similar issues with Ruger magazines.Īs stove pipe issue means fired shell not extracting, you can call it an extraction failure too. This problem looks somewhat like the picture below. Those who can’t pinpoint the reason should take the gun to a gunsmith or send it to Ruger for the right solution. You can understand that jamming occurs for various reasons. It can be the ammo, sights, rough feed ramp, weak spring, and many more. There are other possibilities for potential feeding and accuracy problems. Tighten the tension ring, and the gun is ready to operate smoothly. You can understand that the reason for these problems is unique. If the tension ring on the barrel is not tight enough, you will face these issues. I am calling it a Ruger PC Carbine jamming problem as it covers the whole range of problems due to jamming.įor both ammo feeding issues and accuracy problems, there can be one single reason. Additionally, it can introduce an accuracy problem too. Your PC Carbine may get jammed resulting in a feeding problem. Also, it will allow you to shoot different ammo without any issues. It should do the trick as many users got benefit from the trick. Use a 4” vise grip to hold the ejector and bend it very little so that it can touch the channel in the bottom of the bolt. Lastly, I want to mention a risky DIY fix that requires some alteration of the ejector. If it fails to solve the issue, try replacing the recoil spring and retainer. Or, you can buy these components by yourself. You may urge to modify certain parts of the gun to solve this issue but I don’t recommend it for those who are relying on the Ruger warranty.Ĭontacting Ruger, you may get a new extractor, pin, and spring as a replacement. The obvious first step of this trial and error method is to change the ammo brand. Then, you should inspect all components related to the extraction mechanism.Īlso, don’t forget to check the recoil spring and retainer as they can cause a similar problem too. Possible Reasonsįor the Ruger PC Carbine extractor issue, the first thing to suspect is the type of ammunition you are using. Lots of complaints indicate that Ruger PC Carbine has a problem with ejecting fired shells. Trigger Stuck Replace the weak return spring or the whole trigger kit. Stovepiping Sit the magazine properly, change the ammo brand, and avoid limp wristing. Feeding Failure Tighten the tension ring on the barrel, change ammo, correct the sights, polish the feed ramp, or replace weak springs. Problems Solutions Failure to Eject Change the ammo brand, bend the ejector slightly, or send the gun to Ruger. By building cross-border structures of interconnected companies that trade with one another, global businesses are often able to find ways of unlocking tax savings that no lawmaker intended them to receive. Nike’s tax planning over the years exemplifies how adept multinationals can be at staying ahead of the game. Source: SEC Filings Evolving tax strategies In the three years after that conference call, its after-tax profits would jump by an astounding 55 percent, to $1.88 billion, thanks in substantial part to a drop in its worldwide effective tax rate from 34.9 percent to 24.8 percent – on its way to 13.2 percent last year. Nike’s tax burden hasn’t been the same since. The mechanics of tax avoidance are rarely scrutinized on such calls despite the enormous earnings boost they can provide – and the damage they can do to national treasuries.īehind the scenes, authorities in the Netherlands had effectively given Nike the green light for a 10-year tax-avoidance arrangement that would allow the sportswear-maker to shift billions of dollars in profits from Europe to the tax haven of Bermuda. This had, he said, “secured a big advantage.”Īn advantage over whom or what? How big? What did this favorable agreement entail? These were all questions the analysts did not ask. He reeled off a list of recent achievements, including a brief mention of “a more favorable long-term tax agreement in Europe,” according to a transcript of the call. “So, how are we doing?” he asked himself out loud, almost a year since his promotion to the job. Five days before Christmas 2006, Nike chief executive Mark Parker was in an upbeat mood on a conference call with Wall Street analysts. If it’s determined that the blown pupil(s) are a side effect of medication or chemical exposure, your doctor will likely want to monitor your condition for a day or two to make sure no other symptoms, such as ptosis, appear.Įxamination may reveal that the blown pupils are caused by problems in the brain. A medical professional can assess your symptoms, determine the severity of the situation and prescribe appropriate treatment. Treatment for fixed, dilated pupils depends solely on the cause. Other symptoms associated with this include: The most obvious symptom of blown pupils is having one or both pupils that appear abnormally dilated (large) and do not react to light. Use of anticholinergic drugs, which block neurotransmitters and suppress nerve impulses that cause involuntary muscle movements.Įxposure to plants or other objects that contain these chemicals, such as angel’s trumpet plant, jimson weed and belladonna. Pharmacological blockade, which is a topical drug (usually eye drops) administered before an eye exam. Less serious causes of fixed, dilated pupils include: Trauma or compression of the upper brain stem and third cranial nerve, which is responsible for eye muscles and movement (oculomotor function). Serious causes of fixed, dilated pupils include: The risk involved with a blown pupil is too great to go untreated. While some causes are non-life threatening and may resolve on their own, medical attention is recommended. SEE RELATED: Miosis (pupil constriction) Blown pupil causesįixed, dilated pupils can be caused by several factors. However, exposure to certain substances can also elicit the reaction. Typically blown pupils occur as a response to a brain injury, such as head trauma or stroke. Unilateral cases, where only one pupil is dilated and fixed, is known as anisocoria, meaning unequal pupil size. The largely dilated pupil may affect one eye (unilateral) or both eyes (bilateral). In other words, mydriasis is a temporary dilation of the pupils in response to light.īlown pupils are dilated very widely and fixed, meaning they do not respond to an outside stimulus, such as light. However, once you step out of the dark room, your pupils will return to normal or adjust to the new level of brightness. For instance, when you enter a dark room, your pupils will naturally dilate (get larger) to adjust to a low-light environment. Mydriasis is the eye’s inherent response to stimuli. The key difference between blown pupils and mydriasis is pretty simple: One is a natural, normal response and the other is not. People who notice a sudden, unexplained change in pupil size should see an eye doctor, especially if only one pupil is affected. Typically, blown pupils are seen in response to brain damage caused by trauma or stroke, though less serious causes are possible. When it occurs, a fixed dilated pupil may be present in one or both eyes.
