SRS Scorpion Piston

The Stalker Scorpion piston features an extremely modular design developed from scratch. It offers all the options players could want for their SRS piston. This unique concept uses six weights that form the piston body itself. Since the piston is made up of these weights, it can also be extended with additional weights (short-stroke), reducing cylinder volume and overall joule output.

Morpheus 510MM 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 composition, as it is optimized for machinability. SUS304 steel is harder to machine but offers greater durability and excellent corrosion resistance.

Fluted Teflon Cylinder

This cylinder is a Teflon fluted version of a standard cylinder and gives your SRS A1 or A2 a premium look. The inner coating is applied using a cold treatment process, ensuring the cylinder retains its perfectly straight shape—something that is not always the case with heat-treated cylinders. In addition to improved aesthetics, the special inner coating enhances energy transfer with pistons, potentially increasing joule output if your piston uses a correctly sized 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 2J+ 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 excellent sniper experience. Compared to the Light Pull series, RMS springs are considerably shorter, have a slightly heavier pull, and provide quieter shots. They are also electrically coated to prevent rust, ensuring smoother operation on the spring guide.

Not for Destructive Dogs
Color: Blue
It might be okay for a little dog, but my heeler had it dismantled in short order and I threw it away. Cute toy, but not for a destructive dog.

So cute!
Good size toy, but my 1yr old Jack Russell is NB match for it. It’s good quality and I’m sure it would last longer with a less aggressive chewer.

Dog loves it! Squeaky on both ends!
Bungee rope is not as resistant as I wished, but its fun nonetheless! Squeaks in head and tail. Misssteped the tail and broke one squeaker, still fun though! Toy can handle a beating. Really happy with it!

My dogs loves this toy
I got a few different toys for them today. I need to go through their toybox and get rid of some of the older ones. I can tell the youngster loves the toys. He has taken them into one of the crates and sat with them. Then he brought them back out. He fell asleep with his head against one of them. He has been playing tug of war with this one. And the older one has been running around with it too. Pup already pulled one eye off of this one. But the toy is intact.

SPOT Bungee Raccoon
Purchased 5/20. Decent dog toy. I have a Chiyorkie and he chews on his toys constantly. The squeakers went after a couple of days and then he pulled them out. I put them in the trash. After about two months he had chewed off the head and pulled the bungee out. The bungee went in the trash. I let him play with head and tail pieces for a while but the head had gotten into bad shape so in the trash it went. That left about a twelve inch piece left. He has been playing with that now about a month. He loved tearing the toy up and I do not really blame the toy. He rips up anything that is made of cloth. The only real issue I have with the toy is the two squeakers. IMO they could cause a choking or bowel blocking hazard. I just happened to catch him chewing on them after he had gotten them back. An old knotted on each end knee sock works just about as well but from then on don't leave your socks laying around. They will be fair game for you pet. lol
