Almost. There was a bright orange triangle in place of the red chevron.

The TA33 I have has an amber, not orange, triangle reticle. The USMC standard for this sight is indeed the red chevron in your illustration, but mine was a custom build.

The TA11 on my DMR has the red chevron, but the TA33 is what you were using on the DPMS M4gery.
