Primary Arms joins forces with Trijicon, combining the legendary TA-44 Mini-ACOG with the patented Advanced Combined Sighting System (ACSS®) reticle system. The TA-44 is incredibly small and light, measuring just 4 inches long and weighing in at only 5.1 ounces. The forged 7075-T6 aluminum body stands up to punishing abuse, and the glass clarity is world famous. Inside this TA-44 you will find our patented ACSS® CQB-M5 reticle, combing bullet drop compensation for 5.56 NATO, 5.45x39mm, and .308 Win with automatic ranging. No optic of this size and weight has offered this combination of advanced features before!

This TA44-C-400307 model features green reticle illumination powered by fiber optic light gathering in daytime and tritium in the dark. No batteries are needed. A tall base is machined into the scope body for use on AR-15s and other rifles with an in-line style stock that sits high relative to the Picatinny rail mount.

So the CQB M-5 reticle is small but effective. The horseshoe is perfect for just framing up on the center mass of a target and getting hits out to 50-75 yards on a man sized target. The chevron and the dots are plenty precise for longer shots and track perfectly. The range finding brackets are spot on as well of your eyes are up to the task.. essentially if you can see it then you can kill it. The only weakness is the lack of magnification for target identification further out. However as long as you have clear view of the target the longer hits come easy. The only real con is the ability for you to see the reticle when using a weapon light indoors. It can wash out slightly so just look for the horseshoe.
<br>(After thought) I like the green reticle for daytime outdoors shooting and the red for indoors low light YMMV.

Get your self a little ADM riser for your QD mount so the front sight post is clear to range targets. ADM has the perfect set up for this. If you run flip up front sight it will not matter but I am an A2 guy.

Buy it!


Buy it then let the tears flow that you spent so much before it gets to your door. Then go to the range and hit everything you shoot at and watch your friends drool about how sexy it looks on that rifle lol!



IF I COULD ONLY HAVE ONE OPTIC FOR THE REST OF TIME, IT WOULD BE THIS ONE. Been running this for a year or two on my primary gun, 11.5" 5.56 AR. This thing absolutely slays. For the 11.5" I use various 77gr MK262 flavors and practice with 62gr Wolf 223. Both line up VERY well with this reticle out 500M, but the wolf naturally starts hitting a little low past 300M. I am a mediocre shot at mid-long range. Laying prone anything within 300M is dead first shot. 400-500M I can see perfectly fine and am about 80-90% hits on torso sized targets when wind is down. Drops significantly below that (50/50) if wind picks up (typical afternoon wind is 15-25mph gusts to 30+ here) but no fault of the reticle, just a short barrel/low velocity. You will have to take this optic from my cold, dead hands. It is the best. I'd sell my truck before this optic. Getting a new 2x PA prism with the same reticle as it lines up well for my 16" 308. If I could swing it, I'd get another of these.

buy the correct mount height


i love this optic. there is nothing else to say about it.
<br>if you want a lower 1/3 height, buy a high mount. i initially bought the low mount and that is absolute height.
