ACOG of Choice

[USMC SCAR]

I am looking at the TA33R-9 designed for 308 but I also have several .223 firearms. I want to have some optic interchangeability between rifles.
Would you recommend a different model, one that does not have a bullet drop format? Would an ACOG that just has a chevron or generic reticle be a better choice?

What are you running and how has the interchangeability worked out?

The bullet drop compensator is designed specifically for each caliber, you can interchange the acog if you like, but you will not only have to re-zero the optic, the compensator will not be accurate, ie if its a 7.62 acog, it will not have the same drop rate as the 556. Also, keep in mind the eye relief points, on a 7.62 you want a longer eye relief then the 556, naturally. if you are looking for an interchangeable sight, your best bet would be an aimpoint with a 3x zoom, atleast that way you only have to re-zero between calibers.

I understand that the drop rate is scribed into the ACOG and the drop rate is not interchangeable between calibers. Drop compensated optics are unique to each model and are caliber specific. However it could be zeroed for another caliber at a fixed range.
The most flexible option is to go with a non descript (no drop) ACOG that could be zeroed for each gun.
Some of my other optics turrets/knobs are marked or charted for several guns and or calibers. My current inventory consists mainly of EO Tech, Leupold,Super Sniper, etc.
I have been looking at ACOGs and Aimpoints and find myself leaning towards an ACOG.

I guess my question should have been what ACOG do most Heavy owners prefer and do they mix and match with other calibers and find success?

I had decided to go with the TA11 series. I wanted the extra eye relief and light gathering over the TA33. I ended up with the E version. Not necessarily because it would have been my first choice for a reticle, but because I found an open box return on a clearing house website for $675. That pretty much made up my mind which one to get. I would probably have gone with the horseshoe dot reticle as my first choice. Now that I have it, I am quite fine with the red chevron. Can't help you on the moving scope from one gun to another. I am a one gun one scope kind a guy.

For an ACOG on a 17, I'd recommend the TA11 series. I ran one for awhile and really thought it was a great fit. Only reason I sold it was to fund another optic for a different rifle.

But keep in mind, the BAC is not only caliber specific, it is also ammo and ballistic data specific so unless you match the ammo and ballistic data with what Trijicon calibrated for the BDC, its only gonna be a ball park aiming point anyway. Other than the 100 yard aimpoint (assuming thats where you'd zero it), the BDC is gonna be a swag, close enough to hit a man sized target but not what I'd consider precision shooting... but thats kinda the idea behind a battle rifle and a ACOG...I just bring this up, not to diswade you from an ACOG just that in optics its all about expectation management

That is the exact optic I am wanting for my 17. I use the TA33-R8 for my 16 and want to keep the same setup for my 17. At the moment, I have a Leupold on a LT QD 3-9 x 40 mounted on the 17 that is a nice scope to swap back and forth. If you decide to go a different route and want to get rid of the R9 keep me in mind. I am looking for a deal on one.

I have the TA11J308G and like it. It is 3.5x35 with the green crosshair reticle calibrated for 308. Good eye relief.

With that in mind, any good Acog dealers come to mind. I wanted the TA11J308H, and waited for someone to drop a sale. When they finally did, made the order. It sat on backorder forever and cancelled. A lot of the 308 Acogs don't seem to come info the main stream suppliers very often.

I ran a TA31RCO M150 on my 17 for a long time. The chevron worked great out for 50-200 and the 223 BDC would get you centermass out to 400.
