James, the only difference is 023614851172 comes with an accessory rail and 051981492 does not. Cheers and stay safe!

James, buds is using the incorrect photo for item number 051982492, if you Google the item number you can view the correct photo. But it has an accessories rail for flashlights or lasers. This one item number 051981492 doesn't have an accessories rail. That's the only difference. Other than that they are completely identical. Hope this helps.

they both have the same specs on the browning site They are also both discontinued ***********Item Number
