T1 mount question?

[Moltke]

I frequently switch back and forth from my 1-4 and M4S (both in Bobro mounts) and there is no discernible shift.

I have seen tests with LaRue mounts with a precision rig with the optic removed and remounted between each shot for 20 shots (if I recall correctly), and the group looked like a normal 20 round string from a precision rifle.

Good mounts make it a non-issue if properly mounted.
Still, it's a good practice to confirm zero any time an optic is remounted.

That is amazing. Not so amazing that I'm going to go out and buy new mounts but nevertheless, I would have expected some MOA shift from removal and reattachment to a rail.

The LaRue and ADM are both decent.

I have had issues with ADM mounts loosening.
Tighten them more than you think you need to, and check them frequently for the first few hundred rounds.

I find that the LaRue seats the best if you cycle the latch a few times, gradually increasing tightness until it takes decent effort to unlatch the lock.

I recently mounted my T-1 with Larue QD mount and started with their recommendation of having the latch at about 45 degrees when making first contact. It seemed a little light, so I tightened down the tension nut a little more. Even then, I think mine comes off without much effort once you pull to unlock that little plastic piece. I'll have to see if/how it holds zero over time and I'll have to try the cycling of the latch.

How well do these QD mounts really hold zero?


If you're shooting a 1-4x optic and switch it for a red dot, then sure at close range your red dot will be good enough if it was previously zeroed, BUT putting the 1-4x back on and taking a precision shot at 200 yards? How zeroed is that 1-4x going to be?


I ask because I don't know, I'm not just trying to stir crap up.

I went with the QD as it allowed me to mount the RDS without removing my rear iron site. My rear iron site was a PITA to put on, requiring tapping it into place with a hammer and wood block.

That said, I am also interested in how well the Larue mount returns to or holds zero. I also want to eventually get a 1-4x optic that I can test/try on a few different rifles. I've read good things about ADM mounts, but I'm still a ways off from the 1-4x.

Get the Larue LT660 mount, Its a very nice mount!

Is the only quarrel with the DD lower 1/3 mount that it's not QD?

I wont use a non QD mount optic since taking a class in cool weather and heavy rain. Between the heavy breathing, rain, and smoke the lenses on my T-1 became so fogged up and covered I have rain they my dot was no longer usable. This happened during some competitive drills on the 300yd pop up range and the only thing that saved me was being able to quickly remove my T-1/LT660 and use my irons. The guys with non QD optics didn't fair so well.
