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

Good but heavy smell
Item Package Quantity: 1
I will keep using this bc it works and the sprayer is sooo nice but the smell is so overwhelming. It’s not a bad smell but it’s just so heavy. I’ll use this one but I don’t see myself repurchasing.

Good but confusing instructions
It is very glowy. After spraying this on my husband commented on why I was sweating so much 😹 I told him it’s my face mist spf. I have very dry and very sensitive skin and this has not broken me out (yet). I’ve used it for about a week now. I don’t know how much sun protection I’m really getting though. And reapplying it all through out the day, esp in the summer will lead to very very oily looking skin. It’s also confusing because it says do not spray directly onto face. (?) I just hold my breath and close my eyes tightly before I put my mascara on and spray this. So far it’s been helpful with not making my make up look cakey. There is a smell but it’s not a bad smell, slightly fruity and the smell of spf. If you are sensitive to smells this might not be for you.

So refreshing, you’ll forget it’s sunscreen.
This stuff is fantastic. I love the super fine mist and how easily the pump works. It is soo refreshing and smells like fresh coconut. Ot doesn’t sting or burn my sensitive eyes, and it leaves my skin feeling revitalized and moisturized, not sticky or tacky. It feels amazing when it’s hot outside and you need a quick refresh and it won’t disturb my makeup. Coola is becoming one of my favorite sunscreen brands.

Wonderful hot weather spritz
Size: 1.7 Fl Oz (Pack of 1)
I used this on a recent cruise to the Mediterranean. A lovely spritz on a hot day really was so refreshing! I highly recommend it! And it smells so good!
