NEO-TEC 24/25inch Laminated Chainsaw Guide Bar Saw Chain Combo 3/8 Pitch 0.375 Chain Pitch 0.063 Chain Gauge 84DL for Oregon 243RNDD025 Fit for Stihl MS660 381 066 with 0.063 Gauge Chain

Works like it should perform great it does what what I wanted to do

The chain is sharp and cuts great, The bar has held up well so far, no wear and I guess I have may at least a hundred cuts in 24 to 30 inch locust trees, which is a very hard wood.

Excellent value and excellent cutting with .030 rakers. Teeth are very durable, excellent hardness.

I Installed this 25” bar on a Stihl Ms362. I put about 5 tanks of gas through the saw with the new bar/chain on today and it works great. Chain cuts fine and stayed sharp for a surprisingly long time. I would buy this again in a heartbeat if I needed.

Stihl 660. Works good. Nice price. Sharpens well. Working well after 4 months of use

I put the new Neotec 25 inch bar and chain on my Stihl MS 462 C today and was blown away by the excellent cutting power of the chain! Super sharp! I cut thru 24inch fir logs in about 7 to 10 seconds! In fact, it was kinda scary at how instantaneously the chain sliced thru whatever I touched! I went thru some very thick logs today and that chain is still razor sharp! Oh, and I goofed at one point and got my bar pinched in an angled tree (dumbness on my part), and had to sledgehammer the branch my bar was caught in to free the saw. I was pretty worried that I'd bent the bar, but aside from some chipped paint the bar was fine and I went back to work. I would definitely recommend this bar and chain and will absolutely buy them again if needed.

Did not fit

I put this on a 72cc head and I'm impressed, great performance for the price. Chain holds up as well as any I've used, and the bar is solid.
