Why am I unable to break my "crack barrel" (break barrel airgun)?
You’re likely trying to simply pull it down. Doing so may bend the barrel. Here is the proper method:
Brace the butt of the rifle high on your leg, slap the end of the barrel hard enough to open the breech, then pull down on the end of the barrel.
How do I install the Benjamin Rifle Sling on a break barrel gun?

Are there plans for a single shot tray for the Benjamin Bulldog .357?
The bolt handle moves sometimes when I shot my Discovery Rifle! If flops up a little, but does not open, is that normal?
Yes, this is normal.
This something we have heard about in the past. It happens on some guns and not on others. There is nothing but gravity holding the handle down but as long as the bolt deoe not open, there is no malfunction.
It is possible for the O-ring on the bolt nose to be missing and if this is the case, a replacement may be purchased from Customer Service.

Short Answer:
Yes
Long Answer:
This is something we have heard about in the past. It happens on some guns and not others. There is nothing but gravity holding the handle down. As long as the bolt does not open, there is nothing technically wrong with the gun. Make sure there is an O-ring on the bolt nose. If the O-ring is missing please contact Crosman Customer Service.

I can’t find an EVP for the Vantage NP (model #30021).
Internally, the Nitro Venom (model #CVW1K77NP) is the same gun. The big differences are all external, such as the stock, scope, picatinny rail, compression tube, barrel and lack of iron sight. But its EVP can be used to determine seals and piston parts.

How do you recommend I clean the barrel on my airgun and how often?
You generally do not clean an airgun barrel. One initial cleaning when the gun is brand new, may be all you ever need. It is better to under clean, than over clean. Depending on your equipment you can damage the rifling or more important the Crown (the very end of the rifling, as you exit the barrel).
The only reason to clean a barrel is if you feel the accuracy has been reduced from what is normally expected.
Do not use an uncoated steel rod or steel brushes inside a steel barrel, a brass rod is fine. If it is a Brass Benjamin or Sheridan, use a plastic “pull though” fishing line or use a wooden rod to push a patch through. A one-piece aluminum cleaning rod may also work. There is even less reason to clean a Benjamin, just leave it alone.
Use only clean dry “cleaning patch” of the proper size.
All of our PCP guns that have a Magazine have an internal O-ring in the barrel; care must be taken to not damage this 0-ring. We suggest using only a” pull though” type and start at the muzzle end. Only use a dry patch.
What not to use: Do not use any firearms gun cleaning solvents. Do not use silicone oil.
Some have reported good results using Ballistol or Simple Green as a cleaner. We have not tested this on all our guns so we are hesitant to recommend it. It’s best to stick with the dry patch.
How do you recommend I clean the barrel on my BB gun and how often?
Short Answer
There is no compelling reason to clean the barrel, so don’t.
Long Answer
Because airguns operate with a blast of air, most small particles of residue are blown out of the barrel as the airgun is fired. Occasionally, the bore should be swabbed out with a clean, dry patch. I use no solvents on airgun bores because of the danger of the solvent getting into the valves. The valve seats are usually made of some sort of plastic or rubbery material that can be damaged by cleaning solvents. Just push a dry patch through the bore a couple of times to remove any small particles of lead or other material. Do not allow any gun cleaning solvent to enter the pump mechanism or cylinder compartment of an air or CO2 gun.

What is the difference between petroleum distillate and petroleum based oil?
Short Answer
“Petroleum based oil” is a general term that usually refers to non-synthetic oils used for lubricating something. An example is motor oil that you put in your car’s engine.
“Petroleum distillate” is generally a more flammable product that is use as a solvent. An example is the gasoline you put in your car’s gas tank.
Long Answer
Crosman Pellgun oil is basically a high grade of 30 weight, non-detergent motor oil. The key is the “non-detergent” part, because additives that are put in most motor oils to keep the engine clean, will corrode the seals in the gun.
Petroleum – As a technical term, petroleum encompasses the liquid (crude oil), gaseous (natural gas), and viscous or solid (bitumen, asphalt) forms of hydrocarbons that occur in the Earth, but the meaning is often restricted to the liquid oil form.
So the Pellgun oil is a Petroleum based product, because it is a lubricating oil.
The term “Petroleum distillate” could cover a lot of products. Petroleum distillate products include jet fuel, diesel oil, light fuel oil, lubricating oils, motor oils, heavy fuel oils, tars, and asphalt. As well as others that are solvents like mineral spirits, kerosene, white spirits. Most products that come for petroleum are manufactured by a distillation process, which is what the term Distillate means.
Distillate is more commonly used as an abbreviated form of middle distillate.
Middle distillates generally refer to petroleum products in the boiling range beginning at above 160 degC and ending at below 420 deg C — i.e., between gasoline and heavy fuel oil. These include gas oil, diesel and jet fuel (kerosene).
So if a product has the warning “Contains Petroleum distillate” that is red flag that is should not be used in our air guns.

Frequently Asked Questions benjaminairguns.com
I want to refinish or touch up my airgun stock. Can Crosman tell me what stain or finish they use?
In most cases the products we, or our vendors, use is proprietary and we do not reveal our processes. The products are industrial grade and not normally available to consumers in standard outlets, like paint or home improvement stores.
The best option may be send the stock to a professional gun stock, furniture or cabinet maker. If you prefer to do it yourself, you’ll be best off to strip the finish entirely and start from scratch.

We repaired a Marauder (.25 cal) for a person 3 to 4 months ago. The airgun was leaking and the problem was that the 1763-104 was badly pitted. We replaced the part and it held. The person has sent th
I don’t think anything is wrong with the gauge port assembly, it is doing exactly what we want when someone is pumping water into the gun. We have seen a couple of these units rust and it is more to do with the hand pump and how and where it is used.
The best solution is to steer this customer to a Compressed air tank set up. If they had this issue in just three months of use, they must be using it multiple times per day, every day.
One thing to recommend is the user take a break after 50 pumps to let the pump cool down. Also operate the pump slow and steady when pumping. The hotter it gets, the more moisture it will generate. When bleeding the hand pump, they should open the valve screw rapidly, so that the moisture will be blown out of the base.
Any pump on the market will pull moisture from the air if it is hot and humid. One way to relieve this is to use the hand pump in an air conditioned area.
This being a .25 Caliber gun isn’t helping things, as you get fewer shots per fill.
I still think the hand pump is one of the better solution for filling a gun. We have sold a lot of pumps and the majority of the users have not had this issue. In some cases like this a Scuba or HPA tank may be better suited as the primary means of filling the gun, and keep the hand pump as a back-up.

Yes the new baffles could be used, but all the old baffles would need to be replaced by a new set, plus replace the old O-ring with the new spring.
