"Great! Super high quality and durable and it works. Definitely need some leverage and strength. 10/10

"Successfully converted G&P WOC threads to AEG spec threads. This tool works beautifully! the instructions show a couple 1/4" bolts that can be used (not included). These are required. You need tons of leverage to get it to work, but it's modifying the most important threads on your gun so that's to be expected. I used a hammer's extraction side on the bolts I used and that supplied plenty of leverage. Take it slow and use lube, it'll work great.

Excellent quality tool
Easy to follow instructions
Does the job well

None that I can think of!

"The DRM tool saved my life when I built my new M4 AEG. This thing is durable and turned the impossible threads into the perfect fit. Buyers please note that modding your threads is risky if not done with caution and could damage them. (Use silicone or lithium grease to lubricate constantly while cutting the threads. only do 1/2 and 1/4 turns while cutting)

- helps convert threading on G&P rifles into standard AEG threading
- durable enough to use on multiple rifles for many years.
- only $35!!!

- Requires a strong set of arms and lots of leverage for cutting.
