It includes every option players could want for their SRS piston. It is a unique concept in which 6 weights form the body itself. Since the piston is built from these weights, it is also possible to extend the piston with additional weights (short stroke), which in turn reduces cylinder volume and joules. Morpheus 420MM Inner Barrel The Morpheus hybrid barrel is made from highly durable SUS304 stainless steel and features a conical crown (Dual Bore) to improve range and accuracy. We use the more durable and resistant seamless SUS304 steel because we wanted to raise the bar. Most brands use SUS303 steel because it is easier to machine. The corrosion resistance of SUS303 stainless steel is reduced due to its composition, as it is optimized for machining. The SUS304 steel we use is more difficult to machine but far more durable and offers excellent corrosion resistance. Teflon Cylinder This cylinder is a Teflon-coated version of a standard cylinder. The internal coating treatment is a cold process, so the cylinder maintains its straight shape, which is often not the case with heat-treated cylinders. The cylinder also features a special inner coating that provides better energy transfer with pistons, which may increase joules if your piston has the properly sized cup. This cylinder is fully compatible with Silverback SRS A1 and A2 receivers. This cylindrical thread works with both A1 and A2 bolt handles. This cylinder is compatible with various aftermarket pistons. Rapax 2.8J Galvanized to prevent rust, reduce friction, and provide extended lifespan compared to other springs. *The box is for promotional purposes only and is not included* You can follow us on Instagram, Facebook, or contact us via email: Facebook: https://www.facebook.com/StalkerAirsoftDesigns/ Instagram: https://www.instagram.com/stalkerairsoftdesigns/ Youtube: https://www.youtube.com/channel/UCWsBiSHlu-lbcnGQWAkeJWQ Email: [email protected] For more information about Stalker Products, Tech & Crafting Guides please visit: www.stalkerairsoft.com.

Perfect for me!!
Size: 90 Count (Pack of 1)
This was always my most favorite Magnesium supplement until Smarter Nutrition replaced it with another formula. Marine Derived Magnesium helped me fall asleep and more importantly, by shutting off my thoughts so that if I did wake for any reason, I was able to drift back to sleep quickly!! Am so relieved that they've brought it back! 😴

Size: 90 Count (Pack of 1)
This product is great. I appreciated the avocado oil included and that it's naturally sourced. It helps support sleep, bones, and muscles, which I need. The only thing is, I wish it absorbed faster. Still, overall, a good supplement for daily use.

Great supplement for overall health benefits
Size: 90 Count (Pack of 1)
I really like the features of the magnesium supplement. The fact that it's non-GMO and naturally sourced makes me feel better about taking it daily. I noticed improved sleep and muscle recovery after workouts. Including avocado oil and trace minerals is a nice touch. Overall, a good product for supporting bone, sleep, and muscle health.

Didn't help for sleep
Size: 90 Count (Pack of 1), Size: 90 Count (Pack of 1)
First of all, I want to mention that I do think this is a quality product. Sea-based magnesium has had a good effect on me before and with the combination of AstraGin and avocado oil, this is a solid list of ingredients. AstraGin is a patented proven combo of notoginseng and Astragalus that helps with absorption in small doses. This was my first time trying AstraGin and I was unsure about using it for nighttime use due to the notoginseng, which is stimulating. But I have seen this in some other sleep formulas and they claim it's only meant for absorption and shouldn't stimulate. The first time I tried it at night with some of my usual supplements, I fell asleep easily but all of a sudden woke up 2 hours later and couldn't go back to sleep for 1.5 hrs. I only drifted back to sleeping bc I was so awake and had to resort to THC gummies. I took a couple days off and tried it again and it was the same bad sleep. Your experience might be different from mine because I am very sensitive to a lot of supplements and I think the AstraGin just doesn't agree with my system but I wanted to let other sensitive people know so they can be cautious.
