AIRMARKSMAN FRAG SLUGS .2175 40.1GR 125PCS
These AirMarksman Frag Slugs .2175 40.1gr 125PCS are extremely violent, devastating airgun slugs for hunting and pest control. Effective at long ranges and also deadly accurate, the Frag Slugs are changing the way shooters see airgun slugs.

The next evolution in airgun performance, the Fragmenting Airgun Slug is a breakthrough in both precision accuracy and terminal performance. Engineered with a high ballistic coefficient (BC of .2) and designed to retain energy, as well as stability at extended distances.
Corbin USA precision swaged each slug using advanced tooling, ensuring exceptional consistency shot after shot. What sets this slug apart is its four-petal fragmentation system. Unlike traditional hollow points that collapse inward, this design deploys outward in a controlled, symmetrical pattern on impact. The result is reliable, repeatable expansion rather than chance performance.
This isn’t just another slug. It’s a complete redesign of airgun projectile performance, delivering accuracy, consistency, and devastating terminal results in one package. Upon impact, the front hollow point breaks into multiple pieces (up to five separate segments) for an immediate energy dump and a large wound cavity, while the solid rear section continues for deeper penetration.

Important Notes
We highly recommend a minimum velocity of 830fps for accuracy and stabilisation. This amounts to about 61ft.lbs of muzzle energy, which is considered high power. Of course, you can shoot these slugs with less powerful air rifles. But for precision, accuracy, consistency and also impact, there is more to it than just having enough energy to push slugs through the barrel.
First of, to shoot 40 grain airgun slugs effectively, you need a high-powered Pre-Charged Pneumatic (PCP) air rifle. According to most experts, preferably one capable of producing at least 40 to 60+ foot-pounds (ft-lbs) of muzzle energy. While they can technically be fired at lower energies, these heavy projectiles require high power to maintain the 900–950+ feet per second (FPS) velocity needed for accuracy and downrange performance.
Shooting at lower muzzle energies may get the slugs out of the barrel, though they will be very slow and have a “mortar-like” trajectory. Medium-range shooting can require less velocity and energy, so likewise, you will need more energy for high-velocity, long-range shooting.
A standard pellet barrel may, in fact, not be sufficient. You need a barrel with a faster twist rate like 1:16 or 1:18 and a profile designed for slugs to achieve tight groups. You will also most likely need to tune your regulator to high pressures (e.g., 145-165+ bar) to achieve the necessary speed.
We do not recommend that you shoot these heavy slugs in underpowered setups like springers, pistols, CO2 airguns, etc.
If in doubt, contact us to discuss a custom tune on your suitable air rifle or for specialist recommendations.
About AirMarksman
Whether you shoot competitively or hunt, AM products help your airgun perform at the top of its class. They are a premier manufacturer and importer of high-end airgun and air charging accessories, known worldwide for quality and innovation.
The mission of AirMarksman is to make your airguning experience better. Airgunners tested their curated collection of products to meet the demand for high-quality accessories at competitive prices. Quality made in the United States of America and sold worldwide.
The Backbone Rail for FX Impact airguns is one of their most popular products. Air Marksman dubbed its Backbone Rail System the ultimate precision top rail for the FX Impact Platform. It comes in various sizes and M.O.A. configurations, tying your entire rifle together and also eliminate tolerance stacking. This rail drastically reduces flex in the entire rifle, creating a more anchored and consistent shooting platform. All this, at the cost of only a few grams added to the total weight of the rifle.
Also, they added a bolt retention detent, keeping the cocking handle and bolt probe held in the rear position when opened. This prevents accidental double feeds and removes play in the cocking handle.
Another sought after product from AM, is the FX Impact M3 Thumb Rest. Adjust both the angle and the position of your thumb with this small add on part. It’s as simple as a turn of the paddle, even while shooting. By mounting a thumb-rest on the M3, you benefit from a natural rest for your thumb. Top shooters choose to use one on their competition guns and in the field.
We expect to see a whole range of products from Air Marksman hit the market in the near future.
