Things I liked:Got my Benjamin 397 fixed. Had a gunsmith install the kit since It was kind of difficult to remove the rolling pins that hold the retention cap. Did not want to take the risk of damaging it. This kit works and I commend Crosman for providing this maintenance kit. Just gives you the confidence in buying their guns
Things I liked:Perfect fit for Air force air rifles. Before installing this, I tried a 1" high ring scope mount and I did not have a comfortable viewing position. Once the tri rail was installed with the 1" high ring mount, the viewing set up was perfect.
