Looking for a more robust spring bar for my Exp II, as with the stock bars I have already had a failure when wearing on a Nato strap.

As best I can tell, I am looking for a single shoulder option with a width of 21mm. I realize these will require cutting to remove once installed.

What I am hoping for help with is the following:

Pivot length
Pivot diameter
Total diameter/length.

I thank in advance anyone who can help me out. Cheers!
