Gooseneck RDS Mount

Have a user group stuck with fixed A2 carry handles and swapping receivers is not an option. With the shortcomings of a goosenecked carry handle mount already in mind, what is the current best choice for this type of mount? Anyone newcomers? Vendor?

have you seen this thread?

i’d just go with one of the ARMS carry-handle mounts…

im guessing they don’t have quality railed handguards- but if they do, that is an option. everyone scoffs at it, but in my opinion, putting an RDS on the guard as close to the receiver as possible is better than mounting sights to the end of the guard. if the guard is damaged or otherwise shifts, the RDS, mounted closer to the pivot point, wont shift nearly as much as the site located all the way out at the end.

Yes, I saw that thread. I was hoping there may have been a new refinement in goosenecks.

Goosenecks only for these guys. Upper receiver conversion, railed hand guards, and any other such mod are not an option.
