I used this as it was included with the rental kit, well actually the first time I didn't because I got ahead of myself and forgot to install it. The scope was good and tight so I figured I didn't need it. Well first time out at the range with my AR-10 (.308) my new scope slid a 1/2" in the mounts.
So I reinstalled and realigned it with RingTrue tape and this time and now 400 rounds later it hasn't moved at all.
A great and essential product that is well worth the time to install.
