What is this "Special Ring Base"?

Does anyone have a description?
Capabilities, mounting options, requirements?

Thanks.

It's a mounting system that Trijicon offers - basically they have the lower mounts for a variety of weapons. These mounts attache to the 'upper ring' that is on the scope. These are the 'generic' Compact ACOGs.

The ones most of us buy have the built in AR-15 carryhandle mount and we need to purchase a mount to adapt it to the flattop (which IMHO is not quite as secure as the 'special ring mount'; M16 mount has 1 big screw to secure it while special ring has 4 smaller screws). If you go to Trijicon's website and click products, then Compact ACOG, then select a unit then click in 'Info'. The lower of the 2 scopes shown is a 'special ring' model - note the 2 screw holes on the side for attaching to the mount (there should be 2 on each side).

The problem with the special ring model IMHO is it costs an extra $90 to mount the scope to a M16 (even if it's a carry handle M16) and the scope is the same cost as the M16 ready model. Also with the Carry Handle mount there is no LaRue mount so you're stuck with thumbscrews (if that is important to you).

FYI Cincinatus - You might want to check out this thread (in case you missed it): Brouhaha & Austrian use Compact ACOGs at Front Sight

It seems I'm one of the few that has seen this washout issue so I'm starting to think it might be a problem with my unit rather than an issue with all of them.

I'd love to see pics that detail the mounting hardware.

Visit the Trijicon Site's Compact ACOG Page at the bottom is the list of 'Special Ring Adapters'. Click on them and they will show a photo. Note they have 3 separate heights available for the Special Ring Compact ACOGs for mounting on a flattop.

There is even a mount for Mini-14s

Next question...

Which would be best for mounting on an M14 Bush rifle?:

TA24

TA26

TA39

T­A40

Why?

Hmm tough call its between the 39 and 40. Personally I'd go for the added magnification of the #39 to take full advantage of the range capabilities.

However the #39 has short eye releif so you had best make sure there is enough eye relief for you intended mounting position. If it is too short - then the longer eye releif of the #40 would be my second choice.

The link will not work for me. I cannot find this and would like to read it. Thanks.
