That’s a good point you’ve made about where to place the red dot and how muscle memory plays a part in acquiring the target when you look through the red dot. I only use real steel optics on my replicas and the placement varies depending on the sight and furniture attached. If I’m using my 3xmag then my T1 is above the Magwell on the upper receiver as that’s only place I can fit it. If I’m using no magnification then the optic is closer to the back of the receiver.
@Belphe On the topic of sling point, the rear sling point on the TM is very good and strong. It’s made of steel. However to i’d also recommended a front RSA coz sometimes you just want to carry the rifle in a two point configuration. In fact I do that more than in single point mode.
