For: Echo 1 Rear Sling Adaptor (Version 2) for M4Product Information:
I purchased this sling adaptor about a year ago. It served its purpose very well until it broke at a large airsoft event. Even having a bungi sling didn't keep it from breaking. I then got a chance to see what this adaptor was made of. This adaptor is made of cast aluminum. This metal is not strong enough to hold an expensive AEG. If it were made of steal that would be more than enough but this is not the case.
not strong enough. It will break at the worst time.
