SRS Scorpion Piston

The Stalker Scorpion piston features an extremely modular design, developed from scratch. It offers every option you could want for your SRS piston. This unique concept uses six weights that form the piston body itself. Since the piston is constructed from these weights, it can also be extended with additional weights (short-stroke setup), reducing cylinder volume and joule output.

Morpheus 570mm Inner Barrel

The Morpheus Hybrid Barrel is made from highly durable SUS304 stainless steel and features a dual-bore tapered end-crowning to improve range and accuracy.

We chose stronger and more durable SUS304 seamless steel to raise the performance standard. Most brands use SUS303 seamed steel because it is easier to machine. However, SUS303 stainless steel has reduced corrosion resistance due to its machinability-focused composition. SUS304 steel is harder to machine but significantly more durable and offers excellent corrosion resistance.

Fluted Teflon Cylinder

This cylinder is a fluted Teflon version of a standard cylinder and gives your SRS A1 or A2 a striking appearance. The inner coating is applied using a cold treatment process, ensuring the cylinder maintains its perfectly straight shape—unlike many heat-treated cylinders. In addition to improved aesthetics, the special inner coating enhances energy transfer with the piston and may increase joule output when paired with a properly sized piston cup.

  • Fully compatible with both Silverback SRS A1 and A2 receivers
  • Thread compatible with both A1 and A2 bolt handles
  • Compatible with aftermarket pistons

Rapax 3J+ RMS Spring

The Rapax Modular Spring (RMS) series is manufactured to the same high-quality standards as the Light Pull series. Designed for durability and performance, it delivers an exceptional sniper experience. Compared to the Light Pull series, RMS springs are considerably shorter, have a slightly heavier pull, and provide quieter shots. Additionally, RMS springs are electrically coated to prevent rust and ensure smoother operation on the spring guide.

4.5 SO CUTE
Format: Kindle
Sapphic rivals to lovers?? Family angst??? I often wonder why I even pick up contemporary romance or dark romance stories because they almost always disappoint. Either it’s too much hetero nonsense or boring plotting but this book makes me think make it’s not the genre, it’s the books I’m picking up. I am so in love with the main characters, I loved the witty banter and jabs between these too and also how they sweetened over time. The dialogue was too cheesy for the most part ( more on that later ) and reluctant working together in forced proximity was *chefs kiss* The family angst was in perfect balance with the romance and felt so relatable, I loved to see the development of both characters learning to stand up to their parents. AND ( spoilers ) THAT ONE SCENE WHERE SAGE TELLS NOAHS FMAILY TO GIVE HER RESPECT AND LET HER FINISH HER SENTENCES BEFORE BUTTING IN??? Weak in the knees. Weak in the knees. The smut was perfect( SO MUCH EXPLICIT CONSENT !!! ) , but I think for most people they will want more than we got, especially when the last 10% of the book was a little.. drawn out? ( pun absolutely intended ) in fact the ending being a little slow and out of balance with conflict was one of the only reasons I didn’t give this a full five stars. My other nitpick was that a small portion of the dialogue and the carnival date was a little cheesy. My expectations got higher as the book went along, but once they started dating the clever dialogue got a little too cheddar for me. Overall I would 100% recommend this book and I could see myself re-reading this one or picking up other books by this author.

Slow Burn
Format: Kindle
A distinct and unconventional enemies-to-lovers romance novel. This charming and gradual romance novel was characterized by its witty banter, diverse and well-developed characters, and unique personalities. While the pacing was somewhat slow at times, I found it challenging to maintain my attention throughout the entirety of the book. The storyline, though somewhat predictable, was original in its focus on the struggles of artists seeking self-discovery. The narrative explored relatable issues and challenging family dynamics, making it a satisfying read despite its predictability.

This is amazing!!
Format: Kindle
✨Summary: Noah Blue, having earned a coveted full-time position at a company re-launching the cult classic Queen Leisah, anticipates reaching new heights in her career. However, there's one obstacle in her way: Sage Montgomery, a talented artist promised creative control over Leisah. Forced to collaborate, Noah and Sage must navigate their shared credit and competitive history. As they grapple with drawing together, a more complex challenge emerges — the unexpected journey of falling in love. ✨Review: The highlight of this book for me is the writing of the characters. They are just written extremely well. They aren’t flat or surface level but dynamic and raw, well-rounded individuals. I loved how the relationship between the two main characters developed throughout the book. Even though they were polar opposites, they had great chemistry and complemented each other perfectly. The slow burn, rivals-to-lovers storyline was amazing and not only developed their relationship but also their characters individually. Their relationship felt so realistic and organic, with both Sage and Noah growing and evolving as the story progressed. The author did a fantastic job with characterization, making Noah and Sage feel like real people with relatable issues. Sage, in particular, was a complex and misunderstood character due to her unique way of handling her emotions. As an older sister myself, I could relate to her struggles with responsibility heavy.

Outstanding
Format: Kindle
In my opinion, slow-burn storylines are some of the hardest to pull off. Keeping readers engaged while they wait for that pivotal moment can be a true challenge. That’s why it’s so crucial to get it right — and Outdrawn absolutely does. There wasn’t a single moment when I lost interest. The plot felt refreshing, offering a welcome break from the often-used cheating tropes that dominate many romance novels. The author also excelled in character development. We got to witness the growth of both Pastel and Sage at a pace that felt natural. Their transformation unfolded seamlessly alongside the plot, leaving us with well-rounded, multifaceted characters. One of the things I especially appreciated about this book was how the main characters remained the focus. In many stories, the supporting cast often steals the spotlight, leaving you more invested in their stories. That wasn’t the case here. While the supporting characters — coworkers, family, etc. — were well-crafted and added depth, they didn’t overshadow the protagonists. The focus remained firmly on Pastel and Sage, and that was exactly what I wanted. Outdrawn was, without a doubt, the best book I read this month. And for once, TikTok didn’t disappoint when it came to recommending sapphic romance.

A must-read for my black queer ladies
Format: Paperback
This book delivered from start to finish. As a black, queer woman, it is hard to find relatable sapphic romance novels, so I was delighted to read this one. My thoughts are below in no particular order: I loved all the cultural references and the way the author describes these beautiful characters. The author did a great job developing the characters and the storyline. The enemy to crush to lover theme was a refreshing reprieve from the typical friends to lovers storyline I see so much in sapphic romance novels. The characters are very interesting - I was glad to see the author go with comic artists rather than your typical cliche careers. Both of the main characters, Noah and Sage, have very different upbringings, and each has her own personal issues going on in the background that they have to work through. This helped a lot with character development and I felt like I really got to know these ladies. The romance scenes are spicy and I was here for it! Some authors tend to dance around the love scenes, but this author did not spare any of the sultry details, using a chapter and a half to describe one encounter. Overall, I couldn’t recommend this book enough. It had me turning the pages all weekend long!
