acog ta 31

does anyone know what the triangle reticule is calibrated for? xm 193 or ss 109. thanx in advance, vic

m855 which is 62gr. The 193 is 55gr so trajectory will differ a bit. SS109 is brit 62gr and I know its loaded a bit differently but I dont know how much that changes the trajectory.

The TA31A is calibrated for M193, 20" barrel, mounted in the carry handle.

As are all models TA01, TA11, TA31 that do not come with a flat top mount.

I stand corrected. I am familiar w/ the TA01 NSN and TA31F models exclusively. The above statement is correct.

Personally, I think Trijicon is WAY LATE in bringing the BDCs up to date. The carry handle BDC is a decade or more behind the times.

Yes, but the carry handle .308 BDC almost perfectly matches 75/77gr ammo out of a 16" flat top AR.
And this will probably be the first one they wil discontinue.

Is there really a difference in the BDC in carry handle models vs. the ones that come with a flat top mount as the mount can be removed and the ACOG mounted to the carry handle?
