How It WorksThe gas ram is permanently filled with compressed nitrogen. When the airgun is cocked, the nitrogen is further compressed. When the airgun is fired the nitrogen expands and pushes the piston forward, compressing the air in front of the piston and thus fires the pellet.
The Power Of ChoiceWe offer Gas Rams of various pressures to accommodate the wide variety of user applications.
NY Custom Airguns offers a variety of aftermarket performance upgrades and tuning options for air rifles, paramount of which is our IGT gas ram conversion.
Our gas ram conversion comes as a complete performance tune and includes the following:
- Crony test, pre and post installation (Free report on request)
- Full visual inspection of rifle (Free report on request)
- Clean, de-bur and de-grease the entire rifle
- Clean all small parts in an ultrasonic cleaner
- New seals installed throughout the rifle
- Re-lube correctly
- Install Ram (includes machining of mounting parts if needed)
What is a gas Ram?
Similar to a spring gun in function but without the mainspring. A gas ram is a gas strut not unlike those found in the automotive industry used to hold up car boots. It is placed inside the piston, behind the compression chamber of the rifle. The gas ram is permanently filled with compressed nitrogen. When the airgun is cocked, the nitrogen is further compressed. When the airgun is fired the nitrogen expands and pushes the piston forward, compressing the air in front of the piston and thus fires the pellet. The IGT gas ram system offers a number of advantages over conventional mechanical springs.
What are the advantages?
- Less Vibration
- Gas rams do not produce any vibration. A traditional mechanical spring twists and bends when its compressed and as the rifle is fired. This rapid rotation results in vibration being transferred into the action and more importantly into the barrel as it settles.
- Gas Rams are quieter
- The Reduction in vibration offers another huge advantage over spring powered rifles in the form of drastically reduced noise emanated from the action during firing
- Faster Lock Time
- Gas Rams react much faster than springs when fired. This results in the pellet leaving the barrel much sooner after the trigger is pulled
- They last longer
- Gas rams are far more durable than springs, they require no maintenance, they will never need to be replaced they can be left cocked indefinitely without fatiguing. When a spring is left compressed for a length of time it weakens and becomes susceptible to breakage. Budget air rifle springs generally last around 2000 shots while more expensive springs have a life expectancy of around 5000 shots. Our IGT Gas Rams have been tested through 10 000 cycles without failure. As they come with a lifetime guarantee they will essentially produce an unlimited life expectancy
- Gas rams can be dry fired
- Air rifle main springs are rather sensitive and do not hold up well to abuse. While It is never a good idea to dry fire an air gun, as it causes damage to the seals and other internal components, a gas ram will suffer no damage should you do so. should a lapse in judgment cause you to accidentally dry fire a rifle with a Gas Ram installed you can be safe in the knowledge that no damage will be done to it.
- Gas Rams are more accurate
- Because the pellet gets out of the barrel quicker, it is less deflected by the recoil. They recoil less than a steel main spring that produces the same muzzle energy so it’s easier to keep the rifle on target during the firing cycle.
Which gas ram is right for me?
We offer Gas Rams of various pressures to accommodate the wide variety of user applications. The internal pressure of the gas ram is permanently set prior to installation. While we are able to offer practically any pressure requested by the customer our standard setups are as follows:
- Low Pressure (500 Newton’s or less)
- Generally used when accuracy trumps power. These rams produce less recoil and are best suited to applications where pin point accuracy is desired. Muzzle energy will be decreased with these rams.
- Medium pressure (650 Newton’s)
- These are the most commonly used gas ram as they offer the perfect balance between power and accuracy.
- High Pressure (850 Newton’s or more)
- This gas ram is for those who easily disregard accuracy in the pursuit of achieving the most muzzle energy possible. While our experiments have shown that in many air rifles, more pressure does not necessarily mean more power, there are still many rifles that can benefit from such a set up.
It is important to note that our high pressure gas rams are not suitable for use with scopes. An air rifle with this ram will impart far more force onto a scope than even the biggest centerfire rifles. This increased recoil makes it nearly impossible to mount the scope without it moving during the firing cycle and even “springer rated” scopes will not last long before failing.
