SRS Scorpion Piston

The Stalker Scorpion piston has an extremely modular design which was made from scratch on my drawing table a long time ago. It has all the options people could want for their SRS piston. It is a unique concept where 6 weights form the body itself and as the piston itself is made up of these weights, it is also possible to extend the piston with additional weights (short stroke), which in turn reduces the volume of your cylinder and joule output.

Morpheus 510MM Inner Barrel

The Morpheus Hybrid Barrel is made out of very durable SUS304 Stainless Steel and has a Dualbore tapered end-crowning to upgrade your range and accuracy.

We used the more durable and stronger SUS304 seamless steel because we wanted to step up the game a bit. Most brands use SUS303 seamed steel because it's easier to machine. SUS303 stainless steel's corrosion resistance is weakened due to its composition as it's specialized for machinability, so the SUS304 steel we use is harder to machine but more durable and has wonderful corrosion resistance.

Fluted Teflon Cylinder

This cylinder is a Teflon Fluted Version of a normal cylinder and makes your SRS A1 or A2 look super cool. The cylinder inner coating treatment is a cold treatment, so the cylinder retains its straight shape, which is often not the case with heat-treated cylinders. Your SRS not only gets a boost in looks, but the cylinder also has a special inner coating which provides better energy transfer with pistons and may also increase your joules if your piston has a correctly sized cup.

  • This Cylinder is fully compatible with both Silverback SRS A1 and A2 receivers.
  • This Cylinder thread works on both the A1 and A2 bolt handles.
  • This Cylinder works with aftermarket pistons.

Rapax 3J+ RMS Spring

The Rapax Modular Spring series is made with the same quality standards as the Light Pull series springs. With durability and quality, they are made to give you the best sniper experience. The difference from the Light Pull series is in its length (considerably shorter than the Light Pull series), slightly harder pull, but increased silent shots. Also, RMS springs are electrically coated to prevent rust, which provides smoother operation on the spring guide.

A major upgrade from standard drugstore brands—sophisticated scent & better lather.
I have been a long-time user of standard body washes (think Old Spice, Axe, or Dove Men), but I kept seeing hype about Cremo and decided to see if it was worth the slightly higher price tag. After using the 32oz Spice & Black Vanilla for a week, I can confidently say this is a massive upgrade for your shower routine. ​Here is how it stacks up against the typical grocery store brands: ​1. The Scent is on another level: Most cheaper washes smell like generic "Sport" or "Ocean" cologne. This scent is much more complex and earthy. ​Top Notes: It starts with a sharp, spicy kick (that's the cardamom). ​Finish: It settles into a smooth, warm vanilla and tobacco scent. It smells more like a high-end department store fragrance than a soap. ​Staying Power: The scent actually lingers. If you shower in the morning, you will still catch subtle hints of the warm spices for a few hours, which pairs really well with woody colognes. ​2. Performance & Feel: The consistency is thicker than what I'm used to. You only need one solid pump to get a rich lather with a loofah. Crucially, it rinses clean without leaving that "squeaky" residue that dries out your skin, but it also doesn't leave a slick oily film like some ultra-moisturizing washes do. It hits a perfect balance. ​3. Value: The 32oz bottle is substantial. Because the gel is concentrated, I expect this bottle to last 3-4 months easily, making the cost per ounce very reasonable compared to buying smaller bottles of cheaper stuff every few weeks. ​Pros: ​Sophisticated, "grown-up" scent profile. ​High-quality pump (sturdy, doesn't clog). ​Non-drying formula is great for colder months. ​Cons: ​Potency: The scent is strong. If you are sensitive to fragrance or prefer unscented products, this might be overwhelming. The bathroom will smell like it for a good 20 minutes after you're done (which I enjoy, but keep it in mind). ​Verdict: This bridges the gap between basic hygiene and luxury grooming. If you are tired of smelling like "Blue Sport" and want something warmer and more refined for the fall/winter, this is absolutely worth the switch.

It smells as good as my cologne.
I never go out without a shot of Guerlain L'Homme Idéal L'Intense cologne. Guerlain does not offer a layered line of products with similar scents. I wanted a deodorant and body wash to match. None of the Old Spice scents came close. Axe Oud Wood & Dark Vanilla antiperspirant has more vanilla and is a bit subdued but works. Finding a body wash was harder. Cremo Spice & Black Vanilla Body Wash sounded promising, but I was apprehensive about its scent including tobacco. I did not want to smell like an ashtray. But when I opened the bottle, I was met with a surprising scent from the past. I immediately recognized it as premium Danish pipe tobacco. Most people do not recognize this aromatic scent as coming from tobacco at all. In fact, it smells more like fresh cured tobacco itself, not its smoke. This adds a very pleasant and masculine smell to the body wash on top of the spice, wood, and vanilla scent I was searching for. The scent only lasts a few hours after you rinse off. One push on the dispenser puts enough soap on a shower loofah to wash your whole body. I do not rinse off my loofah; I squeeze the soap out of it to wash my face, then I place it back in its tray next to the bottle. The scent of the remaining soap acts like incense until my next shower. I was also pleasantly surprised to find that this body soap has a rich lather and cleans as well as advertised. I had forgotten the reason I bought the body soap until I used it.
