Listing includes all of the hardware needed to assemble a MHP LMG with Frontline Foam’s STL files. This kit is compatible with MHP Arm’s original STL files, but some assembly may be more difficult since some holes may need to be drilled out wider or deeper / shallower and/or some springs snipped shorter/stretched longer as spring sizes may not line up perfectly.

The LMG designed by MHP (MrHeathPants) is the very first high performance belt fed blaster out there. High rate of fire and high power, this belt-fed flywheeler is a TON of fun to shoot. It ejects empty chain links out the side and lets you feel like a heavy gunner.

Not just another pump action springer of flywheeler. But the highest capacity full auto performance blaster out there.

MHP LMG Features:
– Full auto
– Disintegrating belt ejects empty belt links
– Single trigger both revs and fires
– Spring-loaded pusher makes the blaster jam resistant
– Links can be combined for any length
– Compatible with most short darts
– Designed for a 3s battery, but a 2s can be used to lower FPS and RPM
– Large battery tray can fit most size lipos up to 42mm x 25mm x 124mm
– ALL METAL TT gearbox (not yellow or half metal) WITH custom reinforcement for increased longevity
– STL files to build your own are provided by the designer and a standard hardware version by Frontline Foam
– Original files: Printables
– Frontline Foam easy build files: Free STL File Download Page
– In-progress indepth troubleshooting guide: MHP LMG Troublshooting Guide
– Full video build guide here: MHP LMG Build Guide

    SO MUCH AWESOME!!! I purchased the max rate of fire with the dual stage options and love it! It always catches everyone’s attention, everybody wants to see it/hold it, and it is so much fun to have on the field. The build was very easy to follow using the youtube video, and all parts were easy to print. I think the most difficult part was removing the 3D printed supports (since I printed all the parts), which wasn’t that bad. Some recommendations I would offer is to test print any piece first to ensure your settings are good and save your gcode files so you can quickly reprint a part in the event you break it. This is an awesome kit and so happy I have one! Frontline Foam is the best for having these perfect worry-free kits!

    Great kit. Received all the parts I need to build this blaster. Great support from frontline foam. Its a DIY kit. A lot depends on the users abikity to assemble and print the parts correctly.

    Springs are not the right size. Worst hardware kit I’ve ever purchased. Source hardware yourself.

Is there a version of the hardware kit that doesn’t require soldering? Cuz I’m a$$ at it and I’m looking for one that my 8 brain cells can out together. Just curious John Doe asked on October 10, 2025

is this kit single stage or double stage? im printing the parts and i need to figure out if its single stage or dual stage. Nicole Belleville asked on August 4, 2025

Thanks for reaching out! If you choose your FPS lower than 200 it will be single stage and if you select 200 and up it will be dual stage!
