I purchased two of these slings this year, one each for myself and my 17 yoa son, and we are both very happy with the sling. I have been hunting for 38 years and have used many types of slings and this is the best by far. I had right shoulder surgery two years ago, which is the one used to carry my rifle, and the difference in "carry weight" this sling makes is huge. The cost is very reasonable and well worth it.
Been buying these for shotguns & rifles since the 90's. Had 1 that I could'n't thread thru the buckle (man. Defect). Called cabelas and they sent me a replacement. I saw a complaint that it's not a shooting sling-try taking two throws around your forearm. Not as tight a lock-up as leather but OK. You'll be glad you bought this sling by sundown.
What I like about the Butler Creek Comfort Strech Rifle Sling is that it is light weight, it is not bulky, and when you are out hunting and walking all day, climbing uphill and downhill, this sling provides the best comfort on your shoulders with it's streching motion at the end of the day when you are really tired.
