Introducing the CU-MNDRL-G3 | Copper Receiver Welding Mandrel. Designed to provide HK Factory-Level precision seam alignment and welding of your HK G3 Series Receiver.
One of the biggest challenges in welding the receiver’s thin metal is managing heat build-up. The CU-MNDRL features a full-length Copper (Cu) Alloy Welding Mandrel that acts as a robust heat sink. Significantly reduces heat build-up at the junction seams and trunnion area. Minimizing the risk of burn-through holes, shrinkage and heat distortion.
Why Choose The CU-MNDRL-G3?
Perfect Weld Seams – Every Time
The CU-MNDRL offers a full-length copper mandrel that brings together every weld seam on your HK Receiver flawlessly. No more uneven or ugly welds on your Receiver’s seams.
Prevents Burn-Through Holes & Heat Distortion
The CU-MNDRL’s full-length Copper Receiver Welding Mandrel prevents over-penetration and burn-through. Protecting your HK Receiver and ensuring it remains intact throughout the welding process.
The CU-MNDRL significantly reduces the heat build-up during the receiver welding process which typically causes shrinkage and distortion.
Beautiful Welds, Inside and Out
The CU-MNDRL ensures your receiver seams are not only beautifully welded on the outside but also have minimal over-penetration on the inside of your receiver. This results in stronger, cleaner and more aesthetically pleasing welds.
Lack of over-penetration means eliminating the tedious task of grinding down weld seam bleed-through on the inside of your receiver.
Built To Last
Built from solid high-grade Copper (Cu) Alloy and clear PVD coated, the CU-MNDRL is built to last. The use of premium materials and finishes ensures that your tool withstands the rigors of frequent use, offering you long-lasting durability.
