Trijicon TA31 ACOG with Major Arms ACSS Reticle


U.S.A. –-(–  Trijicon has been a supplier of optics for the US military considering the fact that 1987, when the TA01 ACOG (Sophisticated Combat Optical Gunsite) 4x prismatic scope was adopted.  That optic rapidly distinguished itself as a sturdy, productive force-multiplier for the troops working with it. 1987 was a extended time ago in the optics business, with improvements and generation updates taking place just about yearly for most businesses.  How has Trijicon kept with the occasions?  Has the technologies behind low-magnification prismatic optics been rendered obsolete by low-energy variable optics (LPVO’s)?  Let’s take a appear at the Trijicon TA31 ACOG, featuring the Major Arms patented ACSS reticle.

There is a lot to unpack right here, function-sensible.  Initially, let’s cover the “Bindon Aiming Concept”.  This fundamentally boils down to shooting with each eyes open, anything pretty familiar to most red-dot customers.  The ACOG is capable of getting shot this way as nicely, regardless of getting 4x magnification.  The brain picks up the red chevron atop the blurred background and superimposes it on the focused view from the other eyeball.  When you hold the rifle nonetheless, your brain switches more than to working with the magnified view.  Yes, it performs, and yes it requires some practice to get rapid with.  It can finish up getting practically as rapid as shooting with a red dot at close ranges.

The ACSS reticle in this TA31 ACOG is illuminated, but not by battery energy.  A tritium insert offers some juice to the reticle, although a fiber optic cable brightens the glow when you happen to be out in the sun.  This setup performs nicely, occasionally a tiny also nicely if I am shooting for groups.  But for competitors or combat shooting, this dual-illumination mechanism grabs the eye’s focus rapidly.  On these vibrant variety days when I want to tone the intensity down a tiny, I have a tiny piece of electrical tape to partially obscure the fiber-optic cable.  No batteries necessary.  No electrical connections to corrode, no worrying no matter if or not your optic is prepared when you want it.

Now is a superior time to address the distinction amongst a fixed energy optic like this and the low-energy variable optics that are gaining such recognition these days.  There are 3 main contrasts.  Initially, weight.  A lot of LPVO’s are amongst 12 oz and 20 oz, not like the mount.  The ACOG is 9.9 oz, as shown.  The second consideration is that moving components are usually a lot more susceptible to harm than fixed components.  If durability is a main concern (hello, Winter Strike), easy is tougher.  Ultimately, there is consistency of view.  I have some Nikon LPVO’s and adore them.  That getting mentioned, when I pull up on a target in a hurry, there is a tiny aspect of my brain devoted to producing certain the optic is on the magnification setting that I bear in mind.  With the ACOG and its fixed 4x, each time I “ready, up” it really is the identical point of view.  4 energy fixed magnification could not be the very best for each circumstance, but it really is a definitely superior jack-of-all trades.

Four power fixed magnification might not be the best for every circumstance, but it's a really good jack-of-all trades.

The ACSS (Sophisticated Combined Sighting Program) reticle itself could warrant an complete write-up.  With no dedicating at least 3 paragraphs, I do not know that I will be capable to specify how impressive it is.  This reticle combines bullet drop, wind holds (five mph), operating-target leads and two procedures for rangefinding (height of ~5’10 or center-mass width of 18″).  That is a complete lot of information, but none of it gets in the way of simply working with this optic.

In proof of the above, I mounted this ACOG on an SBR, working with a V7 six.5″ barrel to launch Federal 120gr Powr-Shock rounds in .300 Blackout.  I had planned on working with the reticle’s functions to variety a buck and evaluate my estimation to a rangefinder.

When it came down to it, the only buck I ended up seeing was moving speedy.  I spotted him at about 250 yards out, moving via brush.  Old habits kicked in, I hit the deck behind concealment and made use of my backpack as a rifle rest.  His trail bent closer to me, I’d estimated 200 yards out.  The initial second I had a shot exactly where he stopped at the identical time there was a pause in the gusty wind, I took it.  Initially round hit, I could see the blood spurting out as the buck spun for a couple of quick seconds.  Later my GPS showed from point of fire to point of influence was 192 yards.

This is not an remarkable hunting story by any stretch, but what I took away from it in the aftermath was how seamlessly I was capable to use the ACOG with ACSS reticle.  It was all-natural, unobtrusive and productive.  For a precision rifle optic, there are possibilities superior suited to the job.  For a shot taken rapidly and with a drastic improvement to initial-round hit percentage more than red dots, the ACOG is king.

Moving back to the optic itself, I’d like to point out some of the good touches worked in by Trijicon.  The turret caps are retained by a couple of wires, and the turrets themselves are finger adjustable.  Simple and easy, as it must be.

There is a cause the ACOG line has such a reputation for durability.  The military is an abusive atmosphere for gear.  Getting made use of in Infantry and Unique Operations environments can be an order of magnitude a lot more entropic.  If an optic can survive the nightmare that is a Ranger fire group, it is impressive.  If it can survive getting handed down from one particular rifleman to the subsequent for years throughout a sustained train-deploy-repeat cycle, it becomes a legend.  The Trijicon ACOG and Aimpoint Comp M series have each been vaulted to that hallowed ground.  The Trijicon TA31 ACOG with ACSS reticle runs $1099 at Major Arms.  For a variety toy, a less costly optic will undoubtedly suffice.  For heavy-duty use exactly where only the very best will function, right here it is.
