Does anyone own or sell a Ata shotgun ? Trying to get info on grooved lines on top of reciever. Looks like a dovetail. Trying to set up a dovetail to picatinney weaver mount for a red dot. Anyone know the size of dovetail or a make of mount that will work well on a shotgun. All the mounts I have seen are for airguns. Worried about the recoil. Thanks
