From Waldo Dynamics

The One Spring You Need For Efficiency All Year-Round

Boost your VFC GBBRs performance year-round with the Waldo Dynamics Winter Hammer Spring, precision-engineered for the VFC AR and MCX GBBR platforms. Designed at 75% strength, this hammer spring delivers improved gas efficiency over the stock component but can still be used all year around. 

That's right; despite this being an overall weaker hammer spring you can still use this in peak summer on your usual green gasses. We performed some extensive testing in the last few months in climates all over the world and found no issues with it's capabilities. This is just a very simple upgrade over the stock spring that can be installed within 3 minutes (video guide here).

Finished in a distinctive blue coating, the finish not only reduces friction (giving you a butter smooth shooting experience) but it also helps you tell it apart from other springs you may have.

This product is compatible with;

- All VFC AR based GBBRs (KS1, BCM, URGI, XM series etc)
- VFC 416 GBBR
- APFG MCX GBBR

Mr. Pistol loves these cookies
Size: 8-Pack, Size: 8-Pack
Pistol is extremely picky, and he loves these cookies. He tries to make it last by licking the icing first, but within about five minutes the cookie is gone. The price and cookie size are both great! Definitely will re-order!!!

Cute dog cookies
Size: 3-Pack
I bought these for my sweet grand-dog’s birthday. She and her brothers loved them! The cookies are quite substantial. I didn’t measure them, but they were probably at least 1/4” thick. The pups worked on them for much longer than I expected! I’m very pleased with this purchase!

Super cute, some dogs are unsure about them at first.
Size: 8-Pack, Size: 8-Pack
These dog cookies are soooo cute!! Perfect for a dog birthday or just as a regular treat. You get 8, which is a good amount for the price. They are large cookies as well, so you can break them up and get even more out of them. They are easy to break and don't crumble too much. Your dog might leave crumbs when eating them, though. I love they are vegan and the ingredients are simple. I also give them to my pig! Each cookie is individually wrapped, which keeps them fresh and makes them easy to share. They smell pretty good to me. A subtle scent that smells like something I would eat. My dog was unsure about them at first and tried to hide it instead of eating it, but once I broke it up into smaller pieces, she ate the whole thing. I think she likes the taste but doesn't LOVE it.

Caused Vomiting
Size: 8-Pack
Caused my golden retriever to vomit many times throughout the day on her second birthday. Ruined the whole day for her - who wants to be throwing up all day on their birthday? Ugh.
