Geissele super precision....

[WS6]

Any data on ring-cap torque, yet?

I just received a T1 lower 1/3rd mount this week from Midway. Very nice mount, robust and simple. I did have to make an elevation adjustment when zeroing. The G mount appears to be shorter than the Bobro it is replacing. It honestly feels more like an absolute co-witness. Not sure how I feel about that yet. I'll run it for a while and see if I like the height or not.

I've become a fan of a 1.5-1.6 sight height over top of rail. Bobro's T1 mounts are a bit "low", IMO, so if Geissele is shorter than Bobro's, wow.

Definitely shorter, maybe by 0.09—0.10“. Makes me wonder if I received an absolute co-witness. Does anyone know the part number for the lower 1/3rd mount?

I think geissele is higher than bobros lower 1/3 (which is low), but lower than the bobro high.

Geissele T1 mount lower 1/3: PN: 05-472. The co-witness is 05-401. I bought both 1/3 and cw and returned the cw.

The lower 1/3 ( PN: 05-472 ) is about 0.09 lower than Bobro lower 1/3 ( PN: B13-111-003 ).

I posted something about this last week ( link ).

Negative. The Geissele lower 1/3rd is lower than the Bobro lower 1/3rd.

Thanks. I didn't see the earlier post. Haven't had much time to keep up with the discussion lately.

Just eyeballing center of the optic, it looks pretty darn close to 1.5 with my calipers and a quick measurement. That would put the Bobro around 1.6. Not sure why it would seem "low" for you since both are right in the wheelhouse of where you want to be.

Here are some Pics of my lower third mount, etc.. Also a Pic of the absolute witness mount at 1.410"( the same as the AR's iron sights). I measured from top of the receiver to the center of the T1 objective at approximately 1.530".
The part numbers on the packaging on both of mine are different than what is printed on the mount body. The height works a little better * for me* than the Bobro lower third aimpoint micro mount .

http://www.primaryarms.com/b13-111-003/p/b13-111-003/ The Bobro lower third mount is 1.650" receiver top to optic centerline. Approximately .120" inch higher than the Geissele lower third mount.

05-472 is what I've got also. Didn't look at the package markings though.
