This item is to have us mod your Clone Bolt and valve. !! --   NOT NEW PARTS  --- !!!

You would send in just your bolt and valve.

Once your order comes is we will email you the address to send your bolt to.

Expect a 1-2 day turn around from when we get your bolt in.

How this works

  • You would send in your Bolt and Valve.  --Pictures of these parts are in the main picture
  • Your Bolt will be machine to hold the new spring. You will get a new Pooty spring shipped back with your parts
  • Your Valve will also need to be machined to make room for the new spring
  • You would then be shipped back your modded Bolt, Valve and a new spring
  • Simply drop the spring over your bolt guide and install your parts like you normally do
  • Adjust the Dwell down 8-9 ms on your Clones board
  • All done

 

Please note that some Clones can use a lower dwell then others. The best working dwell setting for this mod seems to be around 8 ms

If you do go lower then a 8ms of dwell time you should watch for a drop in fps or drop off during rapid fire. 8ms to 9ms is what we found works the best with the spring installed

Finally, a sturdy oversized ball my boy can't destroy! And can pick up easily
This is just wonderful! My dog has destroyed all other balls! I think this is finally one he cannot destroy. And I love the holes so he can pick it up and throw it himself. LOL. And it BOUNCES, bringing him endless joy and skill in catching it. Cause you don't know which way it will bounce off the ground. Oversize was just right for him. Glad to have found this great sturdy ball.

Almost perfect...upraised logo should be left off
This toy is great for relentless chewers with strong jaws! It would be almost perfect if it didn't have a "K9" logo in raised rubber on it. That is the place that my aggressive chewer shepherd/bulldog mix focuses on and is able to get small chunks off. Without that logo, he would chew the ball more evenly, instead of fixating on that one spot. He loves this ball and has chewed on it for about an hour off & on each of the 11 days he has had it. Although it is very durable so far, the flaw is the upraised logo.

Perfect for High-Drive Dogs & Surprisingly Durable (six month review)
I use this ring ball for structured fetch and tug sessions with my high-drive German Shepherd mix (91 lbs. at 10 mon.), and it’s easily the best toy we’ve added to our routine. What makes it truly exceptional is how it allows my dog to engage in the full canine predatory sequence: • Chase: He locks in visually and bolts after the ring when I throw it. • Grab & Hold: He brings it back, pins it against my leg, and bites down firmly (the toy—not the leg!)—his way of acting out the natural catch-and-control behavior. • Unalive & Tug: We finish with a strong tug session, which satisfies his instinct to grip and shake—basically his version of “making the toy unalive.” • Settle & Chew: Afterward, he relaxes with a chew toy or eats—completing the full physical and mental cycle in a healthy, balanced way. Durability is outstanding—this toy stands up to intense tug sessions with no tearing or damage, even with a 91 lb powerhouse. My senior dog also joins in for double tug play, and it holds up beautifully to that too. I don’t leave this toy down for chewing—it’s not a chew toy. I use it specifically for fetch and tug, then put it away when we’re done. This keeps it exciting and extends its lifespan. My dog has other chew toys he can use freely throughout the day. This isn’t just another fetch toy—when thoughtful it provides a structured, instinct-satisfying experience that’s mentally enriching and physically engaging. If you have a high-drive or working breed, or a dog who thrives on interactive play, this ring ball is 100% worth it.

Finally, a toy my dog hasn’t murdered
If your dog destroys toys like it’s their full-time job, this stick is the boss-level challenge they didn’t see coming. I gave it to my power-chewer (a pit mix with jaws of steel), and after a week of gnawing, tossing, and dramatic tug-of-war battles, it’s still intact. Not even a dent. I think it might be made of space-grade rubber or the same stuff they use in black boxes. It’s got a good weight to it — heavy enough to feel solid, light enough to toss without pulling a shoulder. No squeaker, no fluff, no sad stuffing guts all over the living room. Just pure chewable glory. Pros: • Actually indestructible (or close enough) • Great for aggressive chewers • No squeaker = peace and quiet • Easy to clean and doesn’t smell weird • Doubles as a fetch toy and chew stick Minor feedback: It’s a bit heavy for small dogs, and it doesn’t bounce or squeak — but if your dog’s into serious chewing, they won’t care. Also, don’t drop it on your foot. Trust me. Final thoughts: This toy is the Chuck Norris of dog sticks. If your pup has shredded everything else, give this a shot. It might just survive — and so might your sanity.

Durable
If you have an aggressive chewer this will hold up for about a month. After about a month of daily use my police k9 will get the ends off. Is it completely indestructible no, does it hold up better then any other toy he’s had absolutely. When you have a dog with super high toy drive you understand nothing is indestructible but I will say a month for a toy to last with my dog is great and I accept the fact I just have to buy new toys monthly. For reference my dog will destroy a Kong in about half the time.
