Im on the fence on whether I want to by an ACOG TA31 with or without RMR.

If I can, Id like to buy without it (to save money upfront) so I can add it later on down the road.

I also want to know if there are some special TA31 models that I should get. I see sometimes I suffix after the TA31(ex. TA31F). What does the suffix mean? is there i suffix i should try to get or avoid?

My goals are 4 by 32 magnification (for 100 to 200 M shots) and the bidon aiming concept for up close targets / target acquistion. eye relief isnt a huge
concern for me in this caliber.

Also, would an ACOG work (other than bullet drop compensator) if I switched out to a 6.5mm upper?

Finally do the basic model TA31's have any type of BUIS (back up iron sights) .

This is for my LAR-15 Rock River, w/ 16" 1:9 twist barrel

Trijicon makes a mount for the RMR that clamps onto TA31 ACOGS. You can view the mount on Trijicon's web site. It is under the RMR accessories.



ETA:  The suffix refers to the type of reticle that particular ACOG has.  I don't know all of the reticles but I do know the TA31F is a red chevron as that is what I have.  The H is the horseshoe reticle and the HG is a green horseshoe reticle.  That's all I know but the Trijicon web site tells all.
