I just used this chain yesterday and it’s amazing right out of the box!
Buck'n Billy Ray suggested these chains in particular on his YouTube channel, and as usual I wasn’t disappointed.
I just put a 32” bar on my MS660 and could purchase these 2 chains for about the price of 1 Stihl chain, not disappointed with my decision. They cut wonderfully, grabbing and eating right into the wood while standing up and bucking logs on the ground. After 3-4 hours of cutting it still looked and worked like I just took it out of the box. Thanks
