Arrived on time. Fits in the barrel of my 20 gauge shotgun. Helps bore siting and made it easier for my 14 y/o granddaughter to get comfortable shooting the shotgun for deer hunting after she fine tuned her site picture at the target range.

Do not purchase! Item didn’t work right out of the box. Amazon wants me to drive 60 miles to return or $8 to pick up at my house for a $10 item! Ridiculous! Just send me a new one!
