The AR Hook, from Present Arms Inc., promises a good deal of convenience in a small package. Designed as an AR cleaning-rod guide & upper-receiver strut, the AR Hook acts as a third hand while cleaning one’s rifle. The component pins to the lower receiver via the rear takedown pin, while simultaneously hooking onto the upper receiver. This holds the upper at the perfect height and angle for cleaning, while leaving the receiver and barrel free of obstruction so one can easily push a cleaning rod through. The AR Hook retails for $9.95. For more information, check out presentarmsinc.com.
