I let my ar50 go, not because of accuracy or recoil. armalites' muzzle break works awesome. the escaping gases will clear the bench of your staple gun, binoculars or scope caps lol.
....the biggest problem you will have is to find a club that allows their use at extended range. after shooting it at 100 or 200 yards it becomes mundane. you need at least 500 yards plus to really enjoy its capabilities. fwiw, bobn
