I have good things to say about Mad River Knife Supply.
I ordered the Leapers UTG Tactical Quad Rails (MTU011) for my YUGO M70.
The product is high quality and Mad River was very quick to ship and had great communication. The price was also great at 64.00

The handguard went together with a perfect fit do to the multiple spacers that it came with. I highly recommend this product and can also say that Mad River Knife Supply took care of me.
