Why Copper?

The use of copper on the cap eliminates the need to rotate your tip to get an even heat up. It  acts as a thermal reservoir that holds heat and evenly distributes it, allowing YOU to choose how dense and dark you want your extraction during your first heat cycle. The copper jacket also acts as a better buffer for combustion, allowing you to worry less about your reaction time after the click

Heat It Up

Our signature logo is more than a symbol of authenticity. The logo on the FMJ serves as a visual reference point for your torch.

For the perfect heat up, direct the flame at the Simrell logo. As the copper heats up, it will begin to change color. When this “hot-spot” is the size of the logo, you’re at the perfect distance to heat the cap. Once it clicks, you will have approximately 60 seconds to clear the bowl.

Advanced Heat Method 

By covering the airport on your stem, you will increase the pressure and the temperature inside of the chamber, resulting in the darkest roast possible. If you leave the airport wide open during your session, you will have lower pressure in the chamber and get a low temp, less dense extraction. To modify your roast, adjust the chamber heat/pressure by adjusting your airport usage.

PLEASE NOTE** Captive cap, Titanium & MVS sold separately.

    It’s works as advertised, I’m really happy with my FMJ :)! Better for single extraction purposes than without it for sure. So far, I’ve been catching myself gravitating to the MVS+FMJ as my main portable to medicate over my usual go-to’s. The future looks great with this imo. Excellent work Austyn 👍!

    The FMJ is a wonderful new accessory to modify and modulate my experience. In addition to having my favorite device being able to be tuned and retuned to vary the profile, now I have in my Blackwood MVS a portable one hitter that extracts the bowl in one heat cycle. No longer do I have to spin the stem or mouthpiece to heat my bowl evenly. This well fitting, chamfered ring of copper works so well, is a game changer! Thanks Austyn and the Simrell Collection team! Btw, I bought 2 and I’m coming back for more!

    10/10 must have accessory. No more spinning for even heat, just consistent even heat every time.

    I sold both of my Anvils by Vestratto for house payments as soon as I got this. I love how Simrell charged only 10 bucks. This is more than worth the cost. It makes any Dynavap hit as hard as an Anvil.

    Amazing add on. I have used a IH for the last few months and this changed me back to the torch. Full flavorful cloudy hit everytime. Kudos!!!

    The FMJ makes the Dynavap into a simpler high vapor production extraction device.

    The standard Cap cools way to fast. It seems like a waste of torch time.
    The need to reheat after clicks only to just to Spin and repeat again gets old fast.
    Thanks to Simrell, now I enjoy total control of the quality of my hit.
    Finally the Dynavap works predictably faster with much better results.
    The cool down is slightly longer. After a large and dense inhale I need a
    bit longer to get ready for the next heat cycle. The Anvil vape is overkill
    with a very long cool down. The SS or Titanium tips on a water pipe
    will fill faster and knock you back in your seat. For $10 Dollars, this is a must
    have. Desktop quality results with just a small addon. Wake up your
    Dynavap and savor the difference. You can give it to a friend and they can
    understand heat the “S” till it clicks. Quality of life enhancement awaits you.

    Wow! What a steal for only 10 bucks.
    This is total game changer for my dynavap`s.
    Tested on both titanium and stainless steal tips, works great on both.
