SPRINGFIELD TRAC-LOCK SWIVEL/ SLIDE NON-LOCKING MOUNT

I give a 2 star rating not because i did not think the item was of good quality, but because the seller can not get my order right. You have the option when you order to order a bracket made for a 2-3/8" or 2-7/8" post. The first time i ordered, i ordered a 2-7/8" bracket, they sent me a 2-3/8". I returned it and wrote a message stating i needed a 2-7/8". The seller sent me another 2-3/8" bracket...smh. I returned it for refund and am ordering one from a different vendor.
