Just an update on the tri-mount that replaces the dust cover (Heres the picture.. http://imagehost.vendio.com/a/12301129/avi...NT-970TR_1.jpg) I got it and it fastens down rock solid. The scope fits perfectly as well as the laser. The mount does not move and stayed zero'd after about 150 rounds. I paid $35 and think it is a great bang for the buck. I'll update you all if I encounter any problems.
