When completing a couple AR-15 Pistol builds from stripped lowers, the two fin style braces didn't come with arm straps. The proposed Draconian ATF 4999 Braced Pistol Evaluation is impossible to pass with a fin style brace if it has no strap on it that can wrap around the arm, if it has an elastic strap. I used a couple dirt cheap 12" long by 1" wide Velcro straps, but they're flimsy, very flimsy. The slots in the fin braces are 1-1/4" wide, making the Velcro straps even flimsier in use. There are no 1-1/4" wide Velcro straps with buckles on them that I could find. The width leaps from 1" to 1-1/2".
The slot width, however, is the same width as a common rifle sling, and for rifles or shotguns without a shoulder stock sling swivel, there are 16" long D-ring straps that can be wrapped around the shoulder stock to provide a D-ring onto which one can hook a sling. These same straps can be used to provide a fin style pistol brace arm strap that satisfies the ATF 4999 strap requirement for fin braces. Amazon sells a pair of them with metal D-rings and extremely sturdy tri-glide buckles for $6.99 and Amazon Prime free shipping. Non-elastic, more than strong enough, and much better than the Velcro.
Amazon 16" D-ring Straps
Installed them onto the two fin braces when they arrived, replacing the flimsy Velcro straps that had been on them:
Magpul BSL Fin Brace (Mil-Spec):
Mission First Tactical Mil-Spec Minimalist Blade Pistol Brace:
Wanted to share my fin style pistol brace strap solution that satisfies the ATF 4999 non-elastic strap requirement.
