Ok so I have the funds saved up for a nice Acog, and I'm debating what the difference is on these two units.
First is the TA31RCO-M150CP http://www.trijicon.com/na_en/products/product3.php?pid=TA31RCO-M150CP I know it has scope covers, and a green tritium unit. Second being the TA31RCO-A4CP http://www.trijicon.com/na_en/products/product3.php?pid=TA31RCO-A4CP I know it's been used by the USMC for the last few years, but other then that I really know nothing about it. Are there any REAL differences between the two units? I've never been active .Mil so it doesn't matter if it's Army or USMC or whatever. I personally am leaning towards the M150. |

All I can say is the TA-31 RCO A4 is. Calibrated for 20" barrels and the TA-31 RCO M4 is calibrated for 14.5" barrels.
I'm don't I ow anything about the M150 except they went on the ARMYs SDM rifle which looks like an M16A4 with a free float barrel. ETA: TA31RCO-A4 and M4 = 3 clicks per inch at 100m TA31RCO-M140 = 4 clicks per inch at 100m. |
