Handmade Rapax springs: manufactured in Europe to provide the best and quietest performance for your sniper airsoft replica, such as SRS / VSR / SSG24.

Confirmed results of reaching 3+ Joules with a standard SRS. FPS may vary depending on the configuration used in SRS, SSG24, or VSR-10.

Results:

  • The 3+ spring delivers between 3J (G-Spec) and 3.8J for longer SRS inner barrels.
  • The Hulk spring delivers between 3.5J (G-Spec) and 4.9J for longer SRS inner barrels.
  • The 2+ spring delivers between 2.3J (G-Spec) and 3J for longer SRS inner barrels

If the Rapax spring shoots too hot for your field limits, you can cut a few coils without damaging the integrity of the spring, as long as it is done correctly.

The first thing you will notice is a lighter pull compared to standard springs — in short: less effort for more joules. The Silverback M160 spring and the Rapax 3+ J require similar pulling force, but the Rapax 3+ J spring delivers more FPS / joules in comparison.

All springs have the same length, use the same material, and have the same number of coils, etc.
The spring wire used in the production of Rapax springs is of the highest quality, ensuring a longer service life compared to other springs.

The tempering process of these springs is carried out to ensure long lifespan and very minimal FPS / joule loss over time.

The springs are manufactured with strict diameter tolerances, preventing the "twang" sound in sniper airsoft replicas.

* Only compatible with 9MM spring guide *

Excellent athletic socks
Size: Large, Color: (100) White / White / Black
Solid athletic socks at a great price. Not too thick, not too thin. Second time I've purchased them. They last longer than most socks I've used in the past too. Only concern is the sizing. I may be reading the sizing chart wrong, but for my size 13 feet it says XL are the correct sock size. I've ordered Large twice and they're perfect. I would imagine the size Large socks would also fit up to size 14 shoe, but probably need to go with XL if foot is lager than 14.

Quality No Show Socks That Are Comfortable and Durable
Size: Large, Color: (100) White / White / Black
These Under Armour no show socks are great for everyday training and casual wear. The cotton blend feels comfortable and they stay in place throughout the day. Getting six pairs in a pack is solid value for a quality brand. They hold up well after multiple washes and the no show style works great with most athletic shoes. A reliable go-to sock.

Comfortable
Size: Large, Color: (001) Black / Black / White
I recently picked up a pair of Under Armour socks, and they’ve quickly become my go-to choice for daily wear and workouts. From the first wear, the fit felt snug and supportive without being too tight. The fabric is lightweight yet durable, and it does a great job wicking sweat — keeping my feet dry even during longer runs or intense gym sessions. One of the things I appreciate most is the arch support and cushioning in the right places. It adds just enough padding where I need it, especially under the ball and heel of the foot, which makes a noticeable difference on days when I’m on my feet a lot. The socks also have a nice breathable mesh pattern that improves airflow.
